Reproductive traits play an important role in population increases and the egg production (EP) abilities of Indonesian local ducks (ILD). The prolactin (PRL) gene is a single chain polypeptide hormone belonging to a family of growth hormone genes that are mainly synthesized in the anterior pituitary gland in all vertebrates. It has a significant effect on reproductive traits and EP. Single nucleotide polymorphisms (SNPs) present in PRL are a useful molecular marker for EP. This study aimed to identify the PRL polymorphisms based on these SNPs and to uncover the associations with reproductive traits in ILD. A total of 280 ILDs consisting of Tegal and Magelang (F0) ducks and their reciprocal crosses, namely, Gallang (F1) and Maggal (F1), were maintained and specific variables were recorded, that is, age at first egg, body weight at first egg, first egg weight, and EP, for 90 days. Allele and genotype frequencies were used to determine the Hardy- Weinberg (H-W) equilibrium. The association between the SNP genotypes of PRL and reproductive traits was analyzed using one-way analysis of variance, following the GLM procedure of SAS. The genotypic effects on the reproductive traits were determined using regression analysis. This study successfully amplified a polymerase chain reaction product of 190 bp, which was used to identify the SNP. Results indicated that PRL in ILDs is polymorphic. A SNP was found at position 164 nt (c.164G >A), consisting of three different genotypes, namely, GG, GA, and AA. The genotypes of Tegal and Magelang (F0), and Gallang (F1) populations were not in H-W equilibrium. The Maggal population (F1) was in H-W equilibrium. Significant associations were detected between the genotypes and EP in all ILDs (p<0.01), following a regression line of y=2.337x+64.605, with a determination coefficient of 0.0188 (r=0.14). PRL can be recommended as a candidate gene for reproductive traits in ILD, especially EP. Keywords: egg production, Magelang, Prolactin gene, reciprocal mating, single nucleotide polymorphisms, Tegal.

Salmonella enterica is an important foodborne pathogen and is recognized as a major public health issue. The emergence of multidrug-resistant (MDR) S. enterica represents a major challenge for national public health authorities. We investigated the distribution of serovars and antimicrobial resistance of S. enterica isolates from clinical swine samples stored at the Veterinary Diagnostic Laboratory, Faculty of Veterinary Medicine, Kasetsart University from 2016 to 2017. Clinical samples were collected and subjected to standard microbiological techniques outlined in the Manual of Clinical Microbiology to identify Salmonella serovars. Susceptibility to antimicrobials was tested by the Kirby–Bauer disk diffusion method using a panel of 14 antimicrobials. A total of 144 Salmonella isolates were identified and the dominant serovar was Salmonella Choleraesuis (66.67%), followed by monophasic Salmonella Typhimurium (18.75%), S. Typhimurium (9.03%), and Rissen (5.56%). The isolates displayed high resistance rates to ampicillin (AMP [100%]), amoxicillin (AX [100%]), tetracycline (TE [100%]), cefotaxime (CTX [89.58%]), ceftriaxone (CRO [87.50%]), chloramphenicol (C [82.64%]), gentamicin (CN [79.17%]), nalidixic acid (NA [72.92%]), and ceftazidime (CAZ [71.53%]). All isolates were MDR, with 29 distinct resistance patterns. The dominant MDR pattern among serovars Choleraesuis and Rissen exhibited resistance to 9 antimicrobials: ( R7-14 AMP-AX-CAZ-CRO-CTX-NA-C-CN-TE). However, all tested isolates were susceptible to AX/ clavulanic acid and fosfomycin. High resistance levels to the third generation of cephalosporins such as CAZ, CRO, and CTX highlight the need for careful and reasonable usage of antimicrobials in animals and humans, especially for S. Choleraesuis infections. Keywords: clinical isolates, multidrug resistance, Salmonella Choleraesuis.

Indonesian cuscuses are now becoming scarce because of the reduction of habitat and poaching. Further, molecular characterization of Indonesian cuscuses is still very lacking. This study aimed to determine genetic markers and phylogenetic relationships of Indonesian cuscuses based on 16S rRNA gene sequences. This study used 21 cuscuses caught from two provinces and 16 islands: 13 from Maluku and eight from Papua. Cuscus samples were taken by biopsy following ethics guidelines for animals. The genome isolation was done using gSYNC DNA Mini Kit (Geneaid Biotech Ltd., Taiwan). The 16S rRNA gene was amplified by primers (16SKUSAF and 16SKUSAR), and the polymerase chain reaction product obtained was 1875 base pair (bp). The analysis of genetic characterization and the phylogenetic relationship was performed using MEGA version X software (https://www. megasoftware.net/). 16S rRNA gene sequencing attained 1598 bp for all samples. Based on the 16S rRNA nucleotide sequences, cuscuses from Papua and Maluku belong to the genus Phalanger and Spilocuscus. Phalanger spp. and Spilocuscus spp. from Papua can be distinguished from Phalanger and Spilocuscus from Maluku, except Spilocuscus from Ternate has a very close relationship with cuscus from Sentani, Papua. Indonesian cuscuses were derived into two clades based on 16S rRNA gene sequence, one group to genus Phalanger and another group to Spilocuscus. Keywords: Indonesian cuscuses, Maluku, Papua, Phalanger, phylogeny, Spilocuscus.

The current study was conducted to explore evidence of hepatitis B virus (HBV) infection in dogs in Nineveh Province, Iraq. Serum samples of 78 dogs were used to (i) estimate levels of the antibodies against HBV through enzyme-linked immunosorbent assay and (ii) measure the activity of liver function enzymes. Seropositive dogs for HBV constituted 9% of total tested dogs. The differences in seropositivity among males compared to females and among different ages were not statistically significant. Liver function enzymes analysis revealed a significant increase in the activity of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase in seropositive dogs compared to those seronegative. Hepatitis B is evident in dogs in Nineveh Province, Iraq, with a significant impact on liver function in affected dogs. It is important to confirm this evidence through molecular tests. Keywords: alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, dogs, Hepatitis B virus.

The study was conducted to observe the effects of dexamethasone (DEX) on the gross study and histomorphometry of liver and on the alterations of biochemical parameters of broilers. Ninety day-old chicks were collected and assigned to one of three groups: The control, Group A, and Group B. The control, Group A, and Group B were fed for 28 days with a homemade ration, a commercial broiler type ration, and a homemade ration with DEX (7 mg/kg feed), respectively. Liver samples were collected from the individual birds after sacrificing on days 7, 14, 21, and 28 of the experiment. Morphometric characteristics (length, weight, color, and texture) of the liver were examined. Histomorphological alterations of the liver were assessed with routine hematoxylin and eosin staining. To measure the biochemical parameters, blood samples were collected on days 7, 14, 21, and 28 of the experiment. Liver function test was performed spectrophotometrically by analyzing serum biochemical markers, that is, alanine aminotransferase (ALT), aspartate aminotransferase, and alkaline phosphatase (ALP). Thin-layer chromatography (TLC) was performed for the detection of hepatic steroids. Hemorrhagic and congested livers were found in broilers of Group B. There were no significant changes found in weight and length of the livers; only numerical decrease in weight and length was observed in birds of Group B. Liver width was increased in Group B on day 21. Histological observation of livers showed accumulation of lipid droplets, congestion of the sinusoids, and central veins in broilers of Group B. Biochemical analyses showed increased levels of ALT in Group B as compared to Group A on day 14 of the experiment. TLC evaluation revealed a positive result in Group B on 28 days of the experiment. The present study results show that DEX may alter the liver morphology and the concentration of ALT in the circulation of broilers. Keywords: broiler, dexamethasone, growth promoter, liver.

Lipopolysaccharide (LPS) is an integral part of the outer cell membrane complex of Gram-negative bacteria. It plays an important role in the induction and stimulation of the immune system. Various LPS purification protocols have been developed. However, analysis of their efficacy is limited by contamination during downstream applications or the public health hazard of LPS. The aim of this study was to evaluate a modified method for extracting LPS as well as assess the purity of the extracted LPS by high-performance liquid chromatography (HPLC) analysis. Further, we evaluated its immunopotentiating function by measuring the relative RNA expression levels of splenic immune-related genes such as interleukin 1β (IL-1β) and interferon-γ (IFN-γ), after intramuscular injection of increasing concentrations of the extracted LPS in specific pathogen-free (SPF) chick. Isolation, identification, and serotyping of Salmonella Typhimurium were performed using chicken flocks. We then performed molecular typing of Salmonella isolates using conventional polymerase chain reaction (PCR). A new protocol for purification of LPS from Salmonella isolate (S. Typhimurium) was conducted. HPLC analysis of the extracted LPS in the current study was compared to existing methods. An in vivo study was performed to evaluate the ability of LPS to induce an immune response by measuring relative IFN-γ and IL-1β gene expression after injecting increasing concentrations of the extracted LPS into SPF chicks. Isolation and serotyping revealed that Salmonella enterica was of the serovar Typhimurium. Confirmation was conducted by molecular typing through conventional PCR. Fractionation of the LPS extract by HPLC revealed a high degree of purity comparable with standard commercial LPS. These results demonstrate the high purity of extracted LPS based on our modified method using propanol and sodium hydroxide mixture. Intramuscular injection of the extracted LPS in 22 day-old SPF chicks, compared to the negative control, revealed significant upregulation of IFN-γ and slight downregulation of IL-1β. The new modified method can be used for high purity LPS extraction and demonstrates effective immunopotentiating activity. Keywords: extraction, high-performance liquid chromatography, interferon-γ and interleukin 1β genes expression, LPS (O antigen), purification, quantitative polymerase chain reaction, Salmonella Typhimurium.

The aim of the study was to determine the benefits of keeping donkeys and associated production challenges under a smallholder farming system in Kenya. A descriptive study was conducted with smallholder farmers keeping donkeys in 13 administrative locations in Kirinyaga County. Data were collected using a questionnaire guide in 13 focus group discussions (FGDs) using participatory epidemiological methods. The FGDs comprised 8-12 participants who were donkey owners. Data were collected through listing, pair-wise ranking, and probing on the benefits of keeping donkeys, challenges faced by working donkeys and the common diseases that affect donkeys in these farms. Data analysis was performed using Kruskal–Wallis non-parametric method to test whether median ranks were significantly different. Other farm level data were also collected using the structured questionnaire and these were analyzed using descriptive statistical methods. The identified benefits included income obtained from the use of donkeys in transportation (Z=5.80) and manure production (Z=3.47), which enabled the farmers to participate in trade activities and improve crop farming. The identified challenges included theft for slaughter (Z=5.99), disease incidence (Z=3.03), road accidents (Z=2.83), and malicious cutting (Z=2.32). Some of the diseases identified were tetanus (Z=5.35), hoof problems (Z=4.55), helminthiases (Z=3.10), and mange (Z=2.24). Participants ranked diseases based on their effects on work output for the donkeys, reducing productivity and often causing death. Addressing these production challenges would optimize donkey use among smallholder farmers. The results presented can be important for policymakers and extension agents regarding the health and welfare of donkeys kept under similar settings. Keywords: benefits and challenges, income, livelihoods, working donkeys.

In repeat breeding, a sexually mature cow fails to conceive even after three or more consecutive inseminations despite being without any clinically detectable reproductive anomalies. This is a major cause of economic loss in livestock farms, particularly in developing countries, where humans and livestock directly compete for food, and the mineral content of animal feed is rarely checked. This study investigated the association between systemic iron, phosphorus, and total protein and estrous cyclicity in crossbred Holstein Friesian cows. Blood samples were collected from 10 normal cyclic and 10 repeat breeder cows 12 h after the onset of estrus. Serum was separated, and iron, phosphorus, and total protein were quantified with spectrophotometry, using standard controls for all three measurement parameters (iron, phosphorus, and total protein). Iron and phosphorus levels were significantly (p<0.05) lower in the repeat breeders group than in the normocyclic group, but no significant differences were found in total protein levels. Repeat breeding is associated with systemic iron and phosphorus levels but is independent of total protein level. Keywords: crossbred cows, estrous cyclicity, normocyclic, repeat breeder/breeding.

Peste des petits ruminants (PPR) is an acute, extremely contagious transboundary viral disease of small ruminants with severe economic consequences, caused by PPR virus. Cost-effective and rapid diagnosis of the disease is essential for prompt management and control. This study aimed to compare the application of a commercial colorimetric loop-mediated isothermal amplification (cLAMP) kit and reverse transcriptase-polymerase chain reaction (RT-PCR) in the diagnosis of PPR in sheep and goats in Southeast Nigeria. Nasal swab samples were collected from West African Dwarf sheep and goats showing clinical signs suggestive of PPR (n=80) and those without any clinical signs (n=140) of the disease. The diagnosis was achieved through detection of PPR viral genome in the samples using a cLAMP kit and RT-PCR. cLAMP assay was done directly on nasal swab samples without ribosomal nucleic acid extraction. A set of six primers targeting the matrix gene protein was used for the cLAMP assay. PPR viral genome was detected by both cLAMP and RT-PCR in 51 (63.8%) of the 80 samples from sheep and goats with signs suggestive of PPR while 14 (10%) of those without signs tested positive for PPR by both assay methods. There was a 100% agreement in the cLAMP and RT-PCR results. However, cLAMP was a faster, easier, and less expensive method compared to RT-PCR. The cLAMP assay demonstrates the potential for a point of care diagnosis in the field and a valuable diagnostic tool in areas with poor electricity supply as well as in a less equipped diagnostic laboratory. Since the reagents are affordable, cLAMP can be a diagnostic tool of choice in the detection and surveillance of PPR virus in countries with limited resources. Keywords: colorimetric loop-mediated isothermal amplification, peste des petits ruminants virus, reverse transcription-polymerase chain reaction, small ruminant diagnostic tool.

Mastitis in dairy cattle is the most common management disorder that causes higher economic losses by lowering production and quality of milk leads to substantial economical loss. The aim of this article was to review worldwide important advances in strategies to control mastitis for production augmentation in dairy cattle. Many scientists worked to identify effective strategies to control mastitis caused by Streptococcus agalactiae, Staphylococcus aureus, and others. It is necessary to identify mechanisms of infection, define clinical and subclinical states of disease, determine exposure time, and identify pathogen-specific characteristics. Evolvement of management strategies that incorporated hygienic procedures (animal, floor, and milkman), post milking standing period of animal and strategic use of antibiotic or herbal therapy at dry-off, nutritional supplementation, fly control, body condition score optimization, etc., resulted in widespread control of mastitis. The udder, teat of animal, scientific management of milking, automatic milking procedure, genetic selection are considered as important factors to control mastitis. As farm management changed, scientists were directed to redefine control of mastitis caused by opportunistic pathogens of environmental sources and have sought to explore management strategies which will maintain animal well-being in a judicial way. Although significant advances in mastitis management have been made changing herd structure, changing climatic scenario and more rigorous milk processing standards ensure that mastitis will remain important issue for future research.

Staphylococcus pyoderma is a common problem in dogs that need a novel treatment rather than antibiotic therapy. The aim of this study was to investigate the therapeutic efficacy, anti-inflammatory, and antioxidative properties of Aloe vera (Aloe barbadensis) gel ointment on dogs' Staphylococcus pyoderma compared to gentamicin ointment. The inhibition zone of A. vera extract 20% and 40% and gentamicin 1% against Staphylococcus aureus was determined on well diffusion agar. Twenty Baladi local breed dogs were used as control negative group before intradermal inoculation with 105 CFU S. aureus. The animals were classified into four equal groups, control positive group without treatment (n=5), treated groups by 20% A. vera gel ointment (n=5), 40% A. vera gel ointment (n=5), and gentamicin ointment 1% (n=5). Topical application of A. vera and gentamicin ointments was carried out twice daily for 2 weeks until complete healing of dogs' pyoderma. Clinical evaluation was recorded. Inflammatory, oxidant, and antioxidant parameters were measured in serum. The inhibition zone of A. vera extracts 20% and 40% was 19 mm and 23 mm, respectively, while gentamicin 1% was 18 mm. The half maximal inhibitory concentration (of A. vera 20% and 40% were 13.70 with R2=0.98. Dogs' pyoderma treated with A. vera gel ointment 20% and 40% were more likely to have low haptoglobin and tumor necrosis factor-α concentrations than gentamicin 1% ([odds ratio [OR]=4.6; 95% confidence interval [CI]=1.31-17.40; p<0.05]; [OR=5.2; 95% CI=1.04-22.30; p<0.05]), respectively. It seems evident that A. vera has therapeutic effect, antibacterial, and anti-inflammatory effects against dogs' staphylococcal pyoderma than gentamicin that would support its further use rather than antibiotics in one health arena. Keywords: catalase, dogs, interleukins, malondialdehyde, pyoderma, serum amyloid A.

Hypersensitivity to house dust mites is a common cause of atopic dermatitis in dogs. The intradermal test (IDT) identifies allergens to be included in allergen-specific immunotherapy. Common mite allergens used for IDT include single source extracts obtained from Dermatophagoides farinae or Dermatophagoides pteronyssinus or multisource extracts from multimite species (mixed mites), as well as a combination of multimite species and proteins from feces and shed skin (house dust). The objectives of the present study were to evaluate the prevalence of mite sensitivity in dogs diagnosed with atopic dermatitis in different Thailand provinces and to determine if positive test results to mite allergens aligned. Eighty-two dogs (median age [range]: 5 years [11 months-11 years]; 51 males and 31 females) diagnosed with atopic dermatitis underwent IDTs with four different mite-related allergens (D. farinae, D. pteronyssinus, mixed mites, and house dust). The skin reactions were reported on a scale of 0-4 and the reactions 2+ were considered clinically relevant. The relationship between IDT results from different allergens was determined using Pearson's correlation coefficient (r). Fisher's exact test was used to compare IDT results for different mite allergens as well as for dogs residing in Bangkok versus other provinces in Thailand. The prevalence (95% confidence interval [CI]) of positive IDT results for D. farinae, D. pteronyssinus, mixed mites, and house dust in dogs with atopic dermatitis was 64.63% (52.30-74.88), 58.54% (47.12-69.32), 47.56% (36.41-58.89), and 35.37% (25.12-46.70), respectively. A moderate correlation was found in IDT results between D. pteronyssinus and house dust (r=0.514), between D. pteronyssinus and D. farinae (r=0.426), and between D. farinae and mixed mites (r=0.423). The prevalence of dogs with positive IDT results for mite allergens with mono-sensitization, bi-sensitization, tri-sensitization, and quadru-sensitization did not differ significantly between dogs residing in Bangkok (11.63%, 18.60%, 25.58%, and 16.28%) and dogs residing in other provinces (12.82%, 30.77%, 35.90%, and 10.26%). The overall sensitivity (95% CI) and specificity (95% CI) of the mixed mites test associated with atopic dermatitis in dogs were 60.32% (47.20-72.40%) and 94.70% (74.00-99.90%), respectively. The overall sensitivity (95% CI) and specificity (95% CI) of the house dust test associated with atopic dermatitis in dogs were 42.90% (30.50-56.00%) and 89.50% (66.90-98.70%), respectively. House dust mites are an important source of allergens for dogs with atopic dermatitis. In the present study, no significant difference in the prevalence of atopic dermatitis was found in dogs living in the urban area compared with dogs living in the countryside. Application of multisource extracts from mites for IDT revealed a higher reaction to mixed mites than that of house dust. Keywords: allergy, atopic dermatitis, dogs, house dust mite, intradermal skin test.

Tick-borne pathogens such as Babesia canis, Hepatozoon canis, and Ehrlichia canis can cause serious disease in canines. Each blood parasite can be associated with different hematological characteristics in infected dogs. Identification of hematological alterations during routine laboratory screening of blood samples from dogs displaying clinical signs is essential for diagnosing blood parasitic infections. This study aimed to evaluate parasitic infections and hematological alterations in blood samples of infected dogs in Southern Thailand. A total of 474 blood samples were collected from dogs presented at the Veterinary Teaching Hospital of the Prince of Songkla University between 2016 and 2019. An automatic hematology analyzer was used to establish hematological values; peripheral blood films were screened for blood parasites and their detection was associated with hematological alterations to determine the odds ratio (OR). This study found that E. canis (n=127) was the most common blood parasite infecting dogs in southern Thailand, followed by H. canis (n=100) and B. canis (n=24). Hematological alterations caused by Ehrlichia infections included anemia, thrombocytopenia, monocytosis, and eosinophilia (OR=14.64, 17.63, 20.34, and 13.43, respectively; p<0.01). The blood samples of Hepatozoon-infected dogs were characterized by anemia, thrombocytopenia, leukocytosis, neutrophilia, and monocytosis (OR=6.35, 3.16, 12.80, 11.11, and 17.37, respectively; p<0.01). Anemia, thrombocytopenia, eosinopenia, and lymphopenia (OR=10.09, 33.00, 20.02, and 66.47 respectively; p<0.01) were associated with B. canis-infected dogs. These data support the fact that hematological abnormalities are a hallmark for the identification of tick-borne infections. The hematological values, hereby reported, can be used as a guideline for the clinical diagnosis of canine blood parasitic infections in Southern Thailand. Keywords: blood parasite, dogs, hematological characteristics, Southern Thailand.

The emergence of antimicrobial resistance (AMR) in commensal organism, such as Escherichia coli of food animals, is an alarming issue for global health. It increases the possibility of transmitting AMR determinant(s) to human bacterial pathogens by transferable genetic materials, particularly by plasmids. Hence, it is important to know which resistant genes are being carried by commensal organisms in food chain in a country and their level of temporal loads. As a result, pre-emptive measures can be advocated with an aim to reduce their risks in their primary source of circulation which consequently would benefit the public health. Commensal E. coli strains from broiler chickens on randomly selected 30 farms and the farm environments were examined for the frequencies of isolation of resistant strains to oxytetracycline and ciprofloxacin. Five birds were randomly selected from each farm to collect cloacal swab samples (total of 150 samples). Furthermore, a total of 150 environmental samples comprising one each from feed, water, soil, litter, and litter damping site of each farm were screened for the isolation of commensal E. coli strains. Strains thus obtained were initially tested for their resistance to oxytetracycline and ciprofloxacin by Kirby–Bauer disk diffusion method. Oxytetracycline-resistant strains were further screened for the presence of resistance determining genes, namely, tetA, tetB, and tetC by uniplex polymerase chain reactions. Risks associated with the isolation frequency of oxytetracycline- and ciprofloxacin-resistant E. coli were also assessed by univariable logistic regression analysis. The results revealed that all E. coli isolates, regardless of the source of origin, were resistant to oxytetracycline, while 78.4% (95% confidence interval [CI] 69.1-85.5%) showed resistance to ciprofloxacin. All the randomly selected (20) oxytetracycline-resistant strains harbored the tetA gene, whereas tetB and tetC were reported in three and two isolates, respectively. After univariable analysis, only one variable, that is, strain 1 of broiler chickens compared to two other strains was found to be positively associated with the isolation of ciprofloxacin-resistant E. coli (odds ratio 12.75 [95% CI 1.0- 157.1], p=0.047). Resistance emerged against oxytetracycline and ciprofloxacin in commensal E. coli strains circulating in live poultry and farm environments in Bangladesh seems to be very high. Thus, human infection with drug-resistant E. coli strains through food chain will critically compromise the therapeutic measures currently available. Keywords: antimicrobial resistance, Escherichia coli, farm environment, poultry.

Ulcerative corneal lesions are common ocular affections encountered in veterinary ophthalmology, having a higher incidence in dogs with brachycephalic conformation. Prompt and effective diagnosis and repair are necessary to avoid corneal perforation and restore vision. Corneal wound healing is a complex phenomenon often resulting in vision impairment as a consequence of corneal fibrosis and pigmentation. The present study investigated the efficacy of decellularized and gamma-irradiated bovine omentum as an extracellular matrix scaffold in the reconstruction of extensive and full-thickness corneal defects, and the cytotoxic effects of mitomycin-C (MMC) to prevent corneal fibrosis and pigmentation. Twelve injured corneas of eleven dogs irrespective of breed, age, and sex were randomly divided into Groups I and II, consisting of six corneas each. Under general anesthesia, corneal grafting with decellularized and gamma-irradiated bovine omentum was carried out in Group I, whereas Group II corneas underwent single time intra-operative application of topical MMC for 2 min before corneal grafting with the same material. Epithelialization of cornea and observations including corneal edema, neovascularization, the extent of pigmentation, corneal clarity, and scarring was recorded on days 7, 14, 21, and 60 postoperatively. All corneas in Group I showed early epithelialization by day 7 compared to Group II where the MMC delayed epithelialization in 50% of the corneas. Visual function scores improved greatly from 0.17±0.17 in Group II on the day of presentation to 1.0±00 by the end of the observation period compared to Group I (from 0.33±0.15 to 0.88±0.11). Although epithelialization and corneal healing were delayed, 50% of the corneas recovered with undetectable corneal scar and melanosis at the end of the observation period in Group II due to the anti-fibrotic effect of MMC. From the present study, it was concluded that re-epithelialization of the cornea was enhanced by corneal grafting with decellularized bovine omentum, and application of MMC was effective in delaying corneal fibrosis and pigmentation. Keywords: biomaterial scaffold graft, corneal ulcer, decellularized bovine omentum, graft assisted corneal healing, mitomycin-C.

Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira. The organism can spread through the urine of infected animals, which can get into water or soil and can survive there for weeks to months. The study was undertaken to detect the pathogenic Leptospira in healthy dogs' urinary shedding by real-time polymerase chain reaction (qPCR). Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira. To detect the pathogenic Leptospira organisms in dogs' urinary shedding, 239 urine samples were collected from healthy dogs from April 2018 to March 2019 from different areas of Haryana. All the urine samples were processed for DNA extraction and qPCR technique was used to detect the presence of Leptospira. Out of 239 urine samples of dogs, none of the samples resulted in the detection of DNA of pathogenic Leptospira organisms. The present study indicated low risk of transmission of Leptospira organisms from dogs' urine to human beings in Haryana. Keywords: Leptospira, leptospirosis, qPCR, lipL32, Haryana.

We performed a retrospective study to evaluate clinical complications and outcomes associated with non-operative management of pelvic fractures in dogs and cats and described owner satisfaction. Based on radiographic findings and fracture location, case records were classified into two groups. Group 1 included animals with acetabulum involvement that underwent conservative treatment plus femoral head-and-neck excision. Group 2 included animals without acetabulum involvement that underwent conservative treatment only. Compliance with rest instructions, time to locomotion recovery, and the evaluation of persistent lameness were data collected from the questionnaire. The level of satisfaction was classified as excellent, good, or bad. Clinical outcome was evaluated at least 10 months after the fracture. Pelvic injuries included sacroiliac luxations (59.52%) and ilial body (35.7%), acetabular (21.4%), pubic (21.4%), and ischial (14.28%) fractures alone or combined. According to the owners, the proposed strategy yielded good to excellent outcomes in dogs and cats in this study, with 95.23% of animals regaining full function of their hind limbs. Two dogs had slight chronic lameness, and some degree of gait abnormality persisted. Because of financial constraints, the chronicity of fractures, or lack of surgical techniques, the surgical treatment of pelvic fractures may not be possible. Non-operative treatment can then be considered to allow the animal to return to acceptable function. Keywords: Cats, dogs, nonsurgical management, pelvic fractures.

Indonesia has two National Artificial Insemination centers and 17 Regional Artificial Insemination Centers. The frozen semen production techniques differed between the centers, including the type of diluent and semen dilution technique. The aim of the research was to compare the quality of frozen Limousin bull semen diluted using different techniques. Semen was collected from three sexually mature Limousin bulls using an artificial vagina. Immediately after collection, the semen was evaluated macroscopically and microscopically. Semen that had >70% motile sperm and <20% sperm abnormality was divided into three tubes and diluted with skim milk-egg yolk (SMEY) using three different dilution techniques: One-step dilution (100% SMEY with 8% glycerol) at room temperature ([RT] 20°C until 25°C) two-step dilution (50% SMEY without glycerol at RT, stored at 5°C; and 50% SMEY with 16% glycerol after 1 h stored at 5°C); and three-step dilution (50% SMEY without glycerol at RT, stored at 5°C; and 50% SMEY with 16% glycerol added twice at 1 h and 1.5 h after being stored at 5°C). The diluted semen was loaded into 0.25 mL mini straws, equilibrated, and frozen using a freezing machine. Sperm motility, viability, membranes, DNA integrity, and concentrations of malondialdehyde (MDA) and aspartate aminotransferase (AST) enzymes were evaluated after thawing. The results showed that there were no significant differences in sperm motility and DNA integrity between dilutions (p>0.05). However, sperm viability and membrane intactness of one-step dilutions were higher than those of three-step dilutions. The concentrations of MDA and AST enzymes of sperm in one-step dilutions were lower than those of three-step dilutions (p<0.05). It was concluded that the one-step-dilution technique was better than three-step dilution for cryopreservation of Limousin bull semen. Keywords: aminotransferase, dilution technique, frozen semen quality, malondialdehyde.

Consistency in producing raw milk with less variation in bulk tank milk somatic cell count (BMSCC) is important for dairy farmers as their profit is highly affected by it in the long run. Statistical process control (SPC) is widely used for monitoring and detecting variations in an industrial process. Published reports on the application of the SPC method to smallholder farm data are very limited. Thus, the purpose of this study was to assess the capability of the SPC method for monitoring the variation of BMSCC levels in milk samples collected from smallholder dairy farms. Bulk tank milk samples (n=1302) from 31 farms were collected 3 times/month for 14 consecutive months. The samples were analyzed to determine the BMSCC levels. The SPC charts, including the individual chart (I-chart) and the moving range chart (MR-chart), were created to determine the BMSCC variations, out of control points, and process signals for each farm every month. The interpretation of the SPC charts was reported to dairy cooperative authorities and veterinarians. Based on a set of BMSCC values as well as their variance from SPC charts, a series of BMSCC data could be classified into different scenarios, including farms with high BMSCC values but with low variations or farms with low BMSCC values and variations. Out of control points and signals or alarms corresponding to the SPC rules, such as trend and shift signals, were observed in some of the selected farms. The information from SPC charts was used by authorities and veterinarians to communicate with dairy farmers to monitor and control BMSCC for each farm. This study showed that the SPC method can be used to monitor the variation of BMSCC in milk sampled from smallholder farms. Moreover, information obtained from the SPC charts can serve as a guideline for dairy farmers, dairy cooperative boards, and veterinarians to manage somatic cell counts in bulk tanks from smallholder dairy farms. Keywords: bulk milk somatic cell count, control chart, dairy farm, smallholder, statistical process control.

Pulmonic stenosis (PS) is the most common congenital heart disease in dogs. This condition causes right ventricle (RV) overload and disrupts overall systolic function. The aim of this study was to examine the alterations of cardiac electrical activity and mechanical function in dogs with PS compared to normal healthy dogs. The ventricular systolic function of dogs with PS was studied. Dogs were divided into two groups, PS (n=13) and control (CONT) (n=12). Measurements of blood pressure, electrocardiography (ECG), and echocardiography were performed. PS dogs had exercise intolerance, with six experiencing syncope. ECG of PS dogs showed higher amplitudes of P, S, and T waves (p<0.01), and a lower R:S ratio (p<0.001) with longer QRS duration (p<0.001) compared to CONT dogs. Echocardiography demonstrated that the pulmonic flow velocity and pressure gradient (PG) between the RV and the pulmonary artery of PS dogs were significantly higher than CONT dogs (p<0.001). The RV free wall thickness to the left ventricular posterior wall thickness ratio and the right atrium to the left atrium diameter ratio was higher (p<0.001), while interventricular septum (IVS) was thicker (p<0.01) in PS dogs compared with CONT dogs (p<0.001). The systolic function in PS dogs showed higher pulmonic valve velocity time integral (PVVTI) value (p<0.001) and longer pulmonic valve ejection time (ET) (p<0.05) than CONT dogs. However, aortic valve VTI (AVVTI) value and aortic valve ET were not significantly different between the groups, although fractional shortening in PS dogs was higher. In PS dogs, PG showed a significant positive correlation with PVVTI:AVVTI ratio (p<0.05). PS had prolonged pulmonic valve opening. The thickening of the RV wall and IVS can cause a detrimental reduction of the left ventricular preload in PS dogs. Keywords: dogs, pulmonic stenosis, ventricular function.

Bligon goat is a crossbreed between Etawah and Kacang goat. This crossbreed goat is mostly reared by small farmers. In vitro maturation allows female goat (does) contributes toward reproduction despite the fact that the animal has been slaughtered. The aim of this study was to determine the in vitro maturation rate of Bligon goat oocytes supplemented with follicle-stimulating hormone (FSH), and their ability for further embryonic development after in vitro fertilization. Experiment was conducted at the Laboratory of Animal Physiology and Reproduction, Faculty of Animal Science, Universitas Gadjah Mada, Yogyakarta, using Bligon goat ovaries obtained from local slaughterhouse around Yogyakarta. One thousand five hundred cumulus-oocyte complexes were matured for 24 h in tissue culture medium 199 supplemented with 50 IU/L FSH or without FSH (control). First, matured oocytes were evaluated its morphology based on the expansion of cumulus cells and PB1 extrusion. Next, 600 oocytes were then stained with 1% aceto-orcein to examine maturation based on changes in the configuration of chromosomes and nuclear membrane breakdown. Oocytes were considered mature when they reached metaphase II. To prove the ability of mature oocytes to develop into embryos, 900 oocytes were processed for fertilization in vitro. The data were analyzed using analysis of variance. The results indicated that FSH supplementation significantly increased oocyte maturation rate (65.21±7.26 vs. 43.25±6.23%) as indicated by extrusion of PB1 and homologous chromosome pairing and lined in the equator. The rate of degeneration was lower in the FSH-supplemented medium (3.21±0.25 vs. 10.17±3.15%). The blastocyst stage of oocyte developed embryos was reached by 12.43±2.15% and 22.28±4.86% of the control and treatment groups, respectively. FSH supplementation significantly improves oocyte maturation and yields mature oocytes for future embryo development in vitro. Keywords: Bligon goat, follicle-stimulating hormone supplementation, in vitro embryo production.

As means for enhancing gastrointestinal (GI) motility, prokinetics have previously been evaluated in different breeds of horses with varying success. No previous studies were conducted to evaluate the effect of prokinetics on the intestinal tract of Arabian horses breed. Using B-mode ultrasound in the quantification of intestinal contractility, this study aimed to compare the impact of neostigmine and metoclopramide on the intestinal motility of healthy Arabian horses. Twenty-one clinically healthy Arabian horses were equally distributed into three groups. The control group was administered with 5 mL normal saline intramuscularly (IM). The second group was administered with neostigmine (0.044 mg/kg body weight [BW], IM), and the third group was administered with metoclopramide (0.25 mg/kg BW, IM). Duodenal, cecal, and colonic contractions were counted through ultrasonography for 3 min (pre-administration and 15, 30, 60, 120, and 180 min post-administration). In the neostigmine group, a significant (p<0.05) increase in duodenal, cecal, and colonic contractions was observed 15 min post-administration compared with that in the control group (15±1.0, 11.33±1.53, and 12.33±2.31 vs. 11.0±2.0, 6.33±0.58, and 5.33±0.58 contractions per 3 min, respectively), continuing to 60 min post-administration for the duodenum and cecum and 120 min for colon and then returning to the normal; however, the metoclopramide group showed a significant (p<0.05) increase only in cecal and colonic contractions 60 min post-administration compared with the control group (11.0±1.0 and 12.33±0.58 vs. 6±1.0 and 5.67±0.58 contractions per 3 min, respectively), continuing until the end of the experiment. Excessive sweating, excitation, and straining were recorded following the administration of neostigmine, whereas no side effects were observed in the metoclopramide group. Neostigmine improves duodenal, cecal, and colonic contractions in healthy adult Arabian horses, whereas metoclopramide only improves cecal and colonic contractions. Metoclopramide appears to be safer and longer acting than neostigmine in the Arabian horse breed. Ultrasonography is a valuable noninvasive tool for the quantification of intestinal contractility. Future studies should consider the use of various dosages of metoclopramide and administration routes and investigate its impact on horses with GI transit disorders and inclusion in colic post-operative care. Keywords: Arabian horse, intestinal contractility, metoclopramide, neostigmine, ultrasonography.

The use of antimicrobials in the control of mastitis is of concern in public health due to their inefficiency in targeting microorganisms. Studies with medicinal plants have risen as an alternative to the use of conventional products. The objective of this study was to evaluate the efficacy of an experimental disinfectant based on the essential oil (EO) from Lippia origanoides in preventing the development of new intramammary infections (IMI) in Holstein cows. The conventional protocol of pre- and post-milking was used and the control (Conventional treatment [CNV]) and experimental (Experimental treatment [PEX]) products containing EO at 120 μL/mL were applied by immersion. Individual milk samples were analyzed using sheep blood agar methodologies and biochemical tests. The efficiency of the treatment was defined by the presence or absence of Staphylococcus aureus, coagulase-negative Staphylococcus, and Streptococcus spp. There were no clinical and subclinical mastitis cases, no lesions in the mucosal of teats, nor dirt score between groups in this study. Both treatments did not influence the occurrence of IMI. The results revealed that PEX acts efficiently against microorganisms compared to the disinfection by the conventional product demonstrating the efficacy of the alternative product on the prevention of new IMIs in dairy cows. Keywords: Intramammary infections, Lippia origanoides, mastitis, pre- and post-milking, teat disinfectant.

Melioidosis is a potentially fatal disease affecting humans and a wide range of animal species; it is often underdiagnosed and underreported in veterinary medicine in Indonesia. This study aimed to characterize morphological and molecular features of Burkholderia pseudomallei, the causative agent of melioidosis which caused the death of a Bornean orangutan. Pulmonary abscess samples were cultured on several types of media, including Ashdown agar, Ashdown broth, and MacConkey agar. Type three secretion system orf 2 real-time polymerase chain reaction (PCR) and latex agglutination tests were performed to identify the bacteria. Morphological characteristics were compared to all previously published morphotypes. Subsequently, the bacteria were characterized by multilocus sequence typing (MLST) and Yersinia-like flagellum/Burkholderia thailandensis-like flagellum and chemotaxis PCR. The results of the genotyping were afterward compared to all genotypes from Southeast Asia. Multiple morphotypes of B. pseudomallei were perceived during the growth on Ashdown agar. Furthermore, it was identified by MLST that the Type I and Type II morphotypes observed in this study were clones of a single ST, ST54, which is predominantly found in humans and the environment in Malaysia and Thailand, although a very limited number of reports was published in association with animals. Moreover, the E-BURST analysis showed that the ST is grouped together with isolates from Southeast Asian countries, including Malaysia, Thailand, Singapore, and Cambodia. ST54 was predicted to be the founding genotype of several STs from those regions. B. pseudomallei ST54 that caused the death of a Bornean orangutan has a distant genetic relationship with other STs which were previously reported in Indonesia, implying a vast genetic diversity in Indonesia that has not been discovered yet. Keywords: Burkholderia pseudomallei, melioidosis, molecular characterization, nonhuman primate, orangutan.

Octamer-binding transcription factor 4 (OCT4) and sex-determining region Y-box 2 (SOX2) are transcription factors whose functions are essential to maintain the pluripotency of embryonic stem cells. The purpose of this study was to derive stem cells for in vitro culture and to maintain their viability and pluripotency, with the goal to obtain a cell line for transplantation in patients with degenerative diseases or injuries. This research focused on examining the effect of low oxygen tension on the ability of bone marrow-derived mesenchymal stem cells (BM-MSCs) to express OCT4 and SOX2 in vitro. BM-MSCs were obtained from femurs of 2000 to 3000 g New Zealand male rabbits. BM-MSCs were divided into three groups to test different culture conditions: A control group under hyperoxia condition (21% O2) and two treatment groups with low oxygen tension (1% and 3% O2). We characterized the BM-MSCs using flow cytometric measurement of cluster differentiation 44 (CD44) and cluster differentiation 90 (CD90) expression. The expression of OCT4 and SOX2 was measured by immunofluorescence staining after 48 h of incubation in chambers with normal or low oxygen tension with controlled internal atmosphere consisting of 95% N2, 5% CO2, and 1% O2 (T1) and 3% O2 (T2). We considered OCT4 and SOX2 as two markers of pluripotency induction. All immunofluorescence data were subjected to a post hoc normality Tukey's honestly significant difference test; all differences with p<5% were considered significant. BM-MSCs were positive for CD44 and CD90 expression after isolation. Oxygen tension culture conditions of 1% and 3% O2 led to OCT4 and SOX2 expression on culture days 2 and 4 (p<0.05), respectively, as compared to the hyperoxia condition (21% O2). Based on the OCT4 and SOX2 immunofluorescence data, we conclude that the stem cells were pluripotent at low O2 tension (at 1% O2 on day 2 and at 3% O2 on day 4), whereas under 21% O2 the OCT4 and SOX2 were not expressed. Keywords: bone marrow, cluster differentiation 44, cluster differentiation 90, culture in vitro, low O2 tension, mesenchymal stem cells, octamer-binding transcription factor 4, pluripotency, sex-determining region Y-box 2.

Hypertension is closely related to oxidative stress conditions, which increases malondialdehyde (MDA) expression and renal damage. Tilapia viscera hydrolysate extract (TVHE) contains compounds and peptides that act as antioxidants. This study aimed to investigate TVHE therapy effect on MDA levels and renal histological conditions in deoxycorticosterone acetate (DOCA)-salt-induced hypertension rats. Tilapia viscera were defatted and hydrolyzed using Alcalase enzyme to obtain TVHE. TVHE antioxidant activity was measured using the 1,1-diphenyl-2-picrylhydrazyl method. Fifteen Wistar male rats were divided into five groups: Normal control (without induced DOCA-salt), DOCA-salt, DOCA-salt+Captopril 5 mg/kg body weight (BW), DOCA-salt+TVHE 150 mg/kg BW, and DOCA-salt+TVHE 300 mg/kg BW. MDA level and renal histology were observed in each group. TVHE half maximal inhibitory concentration values ranged from 3.87±0.35 μg/mL to 42.03±3.55 μg/mL, which were identified as in the very strong Blois category. TVHE and captopril therapy reduced MDA expression significantly (p<0.05) compared to DOCA-salt only. TVHE and captopril therapy also improved glomerular damage in DOCA-salt-induced hypertension rats. TVHE has antioxidant ability, decreased MDA level, and decreased glomerular damage in DOCA-salt-induced hypertension rats. Keywords: antioxidant, hydrolysate, peptide, tilapia, viscera.

Progressive antibiotic resistance has become the primary threat to public health. The search for alternative substances with similar effects is now a global challenge for poultry farming. The aim of this study was to investigate the action of the probiotic Bacillus cereus (BC) and coumarin (CO) on broiler productivity, biochemical indicators of blood, and muscular and liver tissues. The trial of this study included Arbor Acres cross broiler chickens that were grown up to the age of 42 days. The experiment was conducted on 200 broiler chickens divided into four experimental groups of 50 individuals each: The control group received ration without additives (main ration [MR]), the first experimental group received MR+BC, the second received MR+CO, and the third received –MR+BC+CO. A biochemical and hematological analyzer was used to estimate elemental concentrations using inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emission spectrometry. Inclusion of CO and CO+BC in the diet improved growth rates and reduced feed consumption (FC) per kg of live weight gain. Decreased white blood cell count, increased creatinine and triglycerides (CO), changes in aminotransferase and transpeptidase activity, and increases in chemical elements in the liver and pectoral muscles (BC+CO) were observed. The inclusion of BC+CO in the diet contributed to increases in a greater number of chemical elements in the liver (calcium [Ca], K, magnesium, Mn, Si, and Zn) and the pectoral muscles (Ca, Na, Co, Cu, Fe, Mn, Ni, and Zn). The inclusion of CO and CO+BC in the diet improves growth rates and reduces FC in broilers against a background of the absence of mortality during the experiment. Keywords: Bacillus cereus, blood, broilers, coumarin, muscles, productivity.

Newcastle disease (ND) and avian influenza (AI) are two devastating diseases of poultry, which cause great economic losses to the poultry industry and disrupt food security in our country. The use of ND-AI inactive bivalent vaccine is very effective and economical to prevent and control ND and AI disease. Bivalent ND LaSota-AI H9N2 vaccine is not yet available in Indonesia. The inactivated vaccines used in poultry industry often require oil adjuvant to elicit a sufficient immune response. This study aimed to develop the bivalent inactive vaccines containing ND LaSota and AI H9N2 Sidrap isolate which are local isolates as poultry vaccine candidates, and formulated with two different commercial adjuvants, then compared. Two vaccines bivalent were prepared by emulsifying inactivated Newcastle disease virus (LaSota strain) and AI H9N2 Sidrap isolate viruses with Marcol white mineral oil and Montanide ISA70 adjuvants. Both of bivalent vaccines were tested for safety (physical and histopathological at the injection site) and efficacy in specific-pathogen-free chickens. Parameters used for the evaluation of the efficacy were immunogenicity by hemagglutination inhibition and protection percentage. Both bivalent vaccines are safe to use. Post-vaccination (PV) immune response was observed using a hemagglutination inhibition test at 2, 3, 4, 5, 6, 7, and 8 weeks of PV. The bivalent vaccine B gives a better immune response to ND at 2, 3, and 4 weeks of PV (p<0.05) compared to the bivalent vaccine A, but in 5, 6, 7, and 8 weeks, the PV does not show differences in the immune response. The immune response to AI H9N2 showed differences at weeks 2 and 3 PV (p<0.05) with the bivalent vaccine B indicated higher immunity. A single immunization with both bivalent vaccines induces 100% protection in chickens that have been vaccinated against the deadly challenge with the virulent ND virus. Both of bivalent vaccines are safe to use and provide good efficacy against virulent ND viruses, but bivalent vaccine B (with Montanide ISA70 adjuvant) shows better immune response than bivalent vaccine A (Marcol white mineral oil adjuvant). Keywords: avian influenza H9N2 Sidrap isolate, bivalent vaccine Newcastle disease-avian influenza H9N2, Marcol, Montanide ISA70.

Trypanosomosis is a major impediment to livestock farming in sub-Saharan Africa. It is a vector-borne disease caused by several species of protozoan parasites, namely, trypanosomes. The present study aimed to identify the diversity of trypanosome species infecting sheep and goats from Mongo County and to determine the frequency of these parasites. This study was conducted on 286 trypanotolerant goats and sheep from Mongo regions located in South Gabon, using polymerase chain reaction. Analyses showed that the overall occurrence of trypanosomosis in small ruminants was 13.6% (39/286). Our results also showed that two factors, species and season, could affect the occurrence rate of Trypanosoma. A total of six Trypanosoma species were identified, two in sheep (Trypanosoma simiae and Trypanosoma theileri) and five in goats (Trypanosoma vivax, T. simiae, T. simiae Tsavo, Trypanosoma congolense, and Trypanosoma brucei), though Trypanosoma simiae was the most important species. Mixed infections were also found in goats (54.5%) and sheep (3.57%). Our study demonstrated that small ruminants could represent a reservoir of biodiversity for Trypanosoma parasites. Keywords: diversity, Gabon, goat, polymerase chain reaction, Sheep, Trypanosoma.

Jatropha gaumeri Greenm. is commonly used to treat mouth blisters and skin rashes, its latex has analgesic and anti-inflammatory activity on buccal ulcer. This study aimed to demonstrate the wound healing activity of a cream formulation of Jatropha gaumeri Greenm. latex in a murine model, provide a histological assessment of its scarring effects, and identify the family of phytochemicals involved in these effects. Latex was obtained from the cut stalk leaves and young stems of J. gaumeri and stored in sterile tubes with protection from light. Chloroform, ethyl acetate, and aqueous fractions of the latex were obtained. Fifty male Balb/c mice aged 10-12 weeks were divided into 10 groups of five mice: Group 1 corresponded to healthy mice with wounds; Group 2 corresponded to mice with wounds and treated with A-Derma®; and from Group 3 to group 10 corresponded to mice treated with a different latex fraction. A circular skin wound of about 1 cm was made on the paravertebral region of each mouse under anesthetized and aseptic conditions. The wounds were topically treated every 24 h with the respective extracts for 22 days, after which skin tissue specimens were obtained and stained with hematoxylin-eosin and Masson's trichrome. The efficiency of healing was measured by quantifying the tensile strength of the scars. The phytochemicals in the latex were elucidated using thin chromatography. The aqueous latex fraction produced the best wound healing activity and was superior to the positive control. Reepithelialization at the histological level resulted in tissue that resembled healthy skin in terms of the appearance of collagen, the regeneration of hair follicles, and cellularity of the dermis, which showed organized epithelialization. A wound healing efficacy of 97% was observed, and it seems that alkaloids were the phytochemicals mostly likely responsible for these effects. J. gaumeri latex exhibited wound healing activity, possibly mediated by phytochemicals such as alkaloids in the aqueous fraction. Keywords: alkaloids, Jatropha gaumeri latex, wound healing.

This research aimed to know the effect of the use of complete feed on Bali cattle fattening performance seen from the carcass characteristics. The cattle employed in this research were 12 male Bali cattle aged between 2 and 2.5 years old based on the teeth estimation. The average initial body weight of the cattle during the research was 181.50±16.51 kg. The complete feed contained Gliricidia sepium, natural grass, ground corn, bran pollard, and rice bran which have been compiled into three types of ration of T1, T2, and T3. The T1 ration contained standard crude protein (CP) and high energy (11% CP; 72% total digestible nutrient [TDN]), and T2 contained medium protein and high energy (13% CP; 72% TDN), while T3 ration contained high protein and high energy (%15 CP; 72% TDN). The meat percentage of T2 and T3 was relatively the same, but higher than T1 (p<0.05). The bone percentage and meat: A bone ratio of T2 was higher than T1; in contrast, and T3 was relatively the same with T2 and T1 (p<0.05). The weight of slaughter, carcass percentage, and weight of meat, bone, and fat were relatively the same among the treatments. The application of complete feed with protein source from G. sepium with CP and TDN of 13 and 72%, respectively, can improve carcass percentage and meat: A bone ratio of male Bali cattle fattening. The treatments have not had a positive effect on slaughter weight (kg), hot and cool carcass weight (kg), meat and fat weight (kg), fat percentage, and non-carcass (kg). Keywords: Bali cattle fattened, carcass characteristics, complete feed, Gliricidia sepium, meat quality.

Antimicrobial resistance (AMR) has risen as a serious cross-cutting global public health emergency. At the center of this emergency, foods of animal origin have particularly been singled out as possible drivers despite the paucity of information. This study has been formulated to provide answers to the identified critical gaps in the food safety industry and the public health sphere. In particular, this study was undertaken to investigate the AMR of Escherichia coli and Salmonella in raw retail table eggs in Lusaka, Zambia. Accordingly, a cross-sectional study to determine antibiotic susceptibility of E. coli and Salmonella from raw retail table eggs was undertaken. Standard bacteriological methods involving culture and phenotypic characterization were applied. A total of 1080 raw table eggs pooled into composite samples (five eggs per composite sample) translating into 216 distinct and independently identifiable compounded sample units were collected from randomly selected supermarkets and open markets over 4 months (August 2018-November 2018). The eggs were screened for the presence of E. coli and Salmonella within 24 h of sample collection by standard microbiological methods. The Kirby–Bauer disk diffusion technique was used for antimicrobial susceptibility testing using a panel of nine different antibiotics. A total of 216 pooled egg samples were analyzed at two levels of contamination, (i) eggshell and (ii) egg content. From the eggshell, five compounded samples were positive for Salmonella spp. representing 2.31% (5/216), while 34.26% (74/216) were positive for E. coli. On the other hand, samples from egg contents were negative for Salmonella and E. coli. Eggshells were more likely to be contaminated by E. coli compared to the egg content (χ2=20.95, p<0.0001). Imipenem was 100% effective against E. coli isolates. With Salmonella, high resistance was seen in 80% against tetracycline (TE) and 60% to ampicillin (AMP). E. coli showed 94.6% resistance to colistin sulfate, 83.8% resistance to TE, and 59.5% resistance to AMP. Overall, this study has been able to demonstrate the presence of E. coli and Salmonella outside and inside table eggs in Zambia. It has also shown the resistance of identified isolates which poses a serious public health concern given the consumption patterns of these table eggs. Keywords: antimicrobial resistance, eggs, Escherichia coli, retail markets, Salmonella.

Hyperglycemia increases advanced glycation end-product (AGE) production, and the activity of receptor for AGE (RAGE) in testis, which leads to testicular histopathological damage and infertility. This research investigated the effect of black soybean tempeh (BST), purple sweet potato (PSP), and its combination on AGE and RAGE expression and spermatozoa quality in streptozotocin (STZ)-induced diabetic rats. The rats were given high-fat diets for 5 weeks, then were injected intraperitoneally with multiple low doses of STZ (30 mg/kg body weight). Diabetes mellitus (DM) rats were divided into seven groups: DM, DM+glibenclamide, DM+BST, DM+PSP, and DM+combination of BST and PSP in ratio 1:3, 2:2, and 3:1 as C1, C2, and C3, respectively. The rats were treated for 30 days. Testicular AGE and RAGE expression and spermatozoa quality were measured. The combination of BST and PSP significantly decreased AGE and RAGE expression in testicular organs and improved spermatozoa quality compared to the normal group. The combination of BST and PSP can be used as future alternatives to improve spermatozoa quality in DM patients. Keywords: antioxidant, black soybean tempeh, purple sweet potato, spermatozoa.

The CoaguChek® XS (CCX) is a portable coagulation analyzer that is widely used to monitor prothrombin time (PT) in human patients taking oral anticoagulants. It can also be reliably used for screening dogs when PT is in the normal range. Efficacy of the portable CCX coagulation analyzer was evaluated for testing PT in healthy cats and the normal range was established. Blood samples of 82 cats were collected from the jugular vein and PT was measured using both the CCX and an automated coagulation analyzer (ACA). Spearman's correlation was used to measure the strength and direction of association between the two analyzers, while limits of agreement were assessed utilizing Bland-Altman analysis. Range of PT using the CCX was 10.1-14.1 s. Correlation between the two analyzers was moderate but significant (r=0.3465, p=0.0014). Mean difference between CCX-PT and ACA-PT was 1.624 s and standard deviation was 0.890 with 95.1% of the samples falling within the limits of agreement. The CCX is a portable, easy to use coagulation analyzer that requires a small volume of blood and gives results within 1 min. Results showed moderate correlation and good agreement with a standard automated laboratory analyzer. The CCX can be used for screening coagulation testing when PT is in the normal range for cats. However, testing accuracy of the CCX in abnormal PT cats should be further investigated before diagnostic coagulopathy applications. Keywords: cats, CoaguChek® XS, coagulation testing, point-of-care testing, prothrombin time.

Chlamydia psittaci is an intracellular pathogen with a broad range of hosts and endemic in nearly all bird species as well as many mammalian species. Outbreaks contribute to economic losses, especially due to infection of pet birds, poultry, and livestock. Worse, the organism has a zoonotic effect, and transmission to humans results in severe illness. Therefore, proper control measures need to be applied. We conducted a trial for the preparation and evaluation of inactivated vaccine against C. psittaci. Three C. psittaci strains (accession nos.: KP942827, KP942828, and KP942829) were grown in embryonated chicken eggs and then propagated for purification in Vero cells. The immunization experiment was experimentally performed in mice, which then were challenged with a virulent C. psittaci strain. The immunization trial revealed nearly 100% protection after the challenge. The histopathological and immunofluorescence examinations of internal organs revealed that the prepared killed vaccines can effectively reduce chlamydial infection and shedding in animals with the proper level of protection. Our vaccine can be used to control economic and financial losses resulting from avian chlamydiosis, especially those in poultry industries. The zoonotic transmission risk highlights the need for proper control measures. Keywords: Chlamydia psittaci, human, immunofluorescence, inactivated vaccine, poultry, Vero cell.

Veterinary medicine is a high-risk occupation and imparts a risk of physical injuries due to the unpredictable nature of the animals and workplace conditions. This study aimed to identify the associated risk factors and prevalence of work-related injuries, and automobile accidents among veterinarians in India. A cross-sectional study was carried out among veterinarians (n=565). The responses were recorded using a self-administered questionnaire on work-related injuries, automobile accidents, and physical hazards. Work-related injuries due to animals in the past 2 years were reported by more than half of veterinarians (prevalence=54.7%, 95% confidence interval [CI]=50.58-58.79), while two-thirds experienced workplace injuries due to animals during any time of their career. The risk for injury was 1.1 times higher (odds ratio=1.1, 95% CI=0.611, 1.981) for veterinarians with a long job duration (>10 years). Large animal practicing veterinarians faced a higher (2.03 times) risk of injury. Workplace absenteeism due to animal-related injury (up to 15 or more days) was reported by 25.9% (95% CI=22.44-29.68) of respondents, including hospitalizations for 7.8% of veterinarians. More than half of veterinarians suffered from automobile injuries (prevalence=60.9%, 95% CI=6.8-64.8) due to work-related travel in the past 2 years, resulting in workplace absenteeism for 56.2% (95% CI=51.46-60.97) of subjects. The prevalence of needlestick injury among veterinarians was very high and reported as 80.9% (95% CI=77.49-83.99). Recapping of needles significantly increased the risk of needlestick injury by 1.67 times. Veterinarians are at risk of work-related injuries, including automobile accidents. Kicking by animals and needlestick injuries were the most frequent physical hazards. Recapping of needles and responding to emergency calls at night were significant risk factors for needlestick injury and automobile accidents, respectively. Keywords: accidents, needlestick, occupational hazards, physical hazards, veterinarians, workplace absenteeism, work-related injuries.

Iridoviruses, especially megalocytiviruses, are related to severe disease resulting in high economic losses in the aquaculture industry worldwide. The ornamental fish industry has been affected severely due to Megalocytivirus infections. Megalocytivirus is a DNA virus that has three genera; including red sea bream iridovirus, infectious spleen and kidney necrosis virus, and turbot reddish body iridovirus. Megalocytivirus causes non-specific clinical signs in ornamental fish. Cell culture, histology, immunofluorescence test, polymerase chain reaction (PCR) assay, and loop-mediated isothermal amplification assay have been used to diagnose megalocytiviruses. Risk factors such as temperature, transportation (export and import), and life stages of ornamental fish have been reported for the previous cases due to Megalocytivirus infections. In addition, other prevention and control methods also have been practiced in farms to prevent Megalocytivirus outbreaks. This is the first review of megalocytiviruses in ornamental fish since its first detection in 1989. This review discusses the occurrences of Megalocytivirus in ornamental fish, including the history, clinical signs, detection method, risk factors, and prevention measures.
