Brucellosis caused by bacteria belongs to the genus Brucella is an important zoonosis and constitutes a serious public health hazard worldwide including India. The present study aimed to estimate the knowledge of veterinarians on brucellosis, its public health threat, diagnosis, and vaccination. This cross-sectional study was conducted during 2013-2015 and 453 veterinarians representing 11 states/Union Territories (UT) of India (Assam, Tripura, Meghalaya, Goa, Karnataka, Madhya Pradesh, Uttar Pradesh, Delhi, Jammu and Kashmir, Tamil Nadu, and Punjab) were interviewed using self-administered questionnaire. Out of 453 veterinarians, 71.74% stated handling of the animals on day-to-day basis and 28.25% were engaged in administration activities. The veterinarians ranked foot-and-mouth disease and brucellosis at the first and fourth ranks among the list of ten economic impacted diseases in the country. A significant association was observed between laboratory confirmation with those who handled brucellosis-suspected cases (p=0.000). Similarly, significant association was noted for the availability of vials/slides (p=0.114), vacutainers (p=0.008), icebox (p=0.103), and refrigerator (p=0.106) for those who preferred laboratory diagnosis. Only 20% of the veterinarians recommended vaccination against bovine brucellosis, and 17% obtained laboratory confirmation for the brucellosis-suspected cases. The study highlighted the need for awareness programs, laboratory facilities, veterinary doctors, and protective measures for the veterinarians for combating brucellosis through the control program in the country. Keywords: brucellosis, control program, India, knowledge, veterinary professionals.

Blastocystis spp. is a gastrointestinal parasite that can infect both humans and animals and has the potential to become a zoonotic parasite. This study analyzed a subtype (ST) of Blastocystis spp. that had infected beef cattle in Kamal and Socah, Bangkalan, Madura, Indonesia. Fresh stool samples were collected from 108 beef cattle at Kamal and Socah, Bangkalan, Madura, Indonesia. Blastocystis spp. were detected both morphologically and genetically based on the 18S rRNA gene. The morphology of Blastocystis spp. from the stool samples and cultured samples were observed under a light microscope. Blastocystis spp. from 20 positive cultures were amplified through polymerase chain reaction, and the resultant sequences were identified by ST. One hundred and eight (100%) fecal samples from the fresh or cultured stools were positive morphologically for Blastocystis spp. Molecularly, all 20 of the samples selected for DNA analysis were found to be Blastocystis spp. ST 10. Based on morphological and molecular detection, the prevalence of Blastocystis spp. infection in beef cattle within Kamal and Socah, Bangkalan, Madura, Indonesia, was high. About 100% were non-zoonotic parasites. This was the first report of Blastocystis spp. ST 10 found in infected beef cattle in Kamal and Socah, Bangkalan, Madura, Indonesia. Keywords: beef cattle, Blastocystis spp. subtype 10, Madura, Indonesia, zoonotic.

The research aimed to study the effect of interferon (IFN)-based drugs on the behavior of immunological parameters in calves during the specific prevention of associative infections. The object of research was 45 black motley cows and their calves from birth to 2 months of life. Serum and colostrum samples were screened for antibodies against Rotavirus, diarrhea, and coronavirus using serological methods. The testing was performed before vaccination, 40 days before calving, 20 days before calving, and before calving. Colostrum samples were taken during the first milk yield. Serum samples from calves were drawn before colostrum feeding as well as at 7, 14, and 21 days, and 1 and 2 months of age. To measure the level of immunoglobulins A, M, and G, additional serum samples were collected from calves at 25, 35, 65, and 75 days after birth. Giving pregnant cows, an IFN-based drug at a dose of 1 ml/kg 48 h before vaccination results in the development and accumulation of antibodies to Rotavirus, coronavirus, and viral diarrhea (VD) in the colostrum, with a titer of 7.6±0.3 log2, 5.8±0.34 log2, and 4.4±0.18 log2, respectively. It indicates an increase in the antigenic activity of the multivalent vaccine. IFN-based drugs enhance the protective effect of vaccination against associative infections in the newborn calves. They stimulate a rise in the titer of antibodies to Rotavirus, coronavirus, VD, and mucosal disease complex as well as an increase in immunoglobulins A, M, and G. Keywords: antibody titer, coronavirus, immunoglobulins A, M, and G, interferon, Rotavirus, vaccinations.

According to the previous study, the circulating canine parvovirus (CPV) in Thailand is 2a and 2b. Nowadays, CPV mutants, including CPV-2c, have been identified in many parts of the world. This study aimed to investigate the genetic diversity of the circulating CPV in Thailand. Eighty-five CPV-positive fecal samples were obtained from dogs with either acute hemorrhagic diarrhea or diarrhea. The complete VP2 gene of these samples was amplified using VP2 specific primers and polymerase chain reaction (PCR). The obtained full-length VP2 sequences were analyzed and a phylogenetic tree was constructed. Sixty and 25 CPV-positive fecal samples were collected in 2010 and 2018, respectively. Thirty-four samples were new CPV-2a and 31 samples were new CPV-2b due to amino acids substitution at position 297 (Ser-Ala). In 2018, 5 new CPV-2a, 19 CPV-2c, and 1 feline panleukopenia virus (FPV) were found, but no new CPV-2b was detected. Moreover, most of the CPV in this study had amino acids mutations at positions 324 and 440. The phylogenetic construction demonstrated the close relationship between the current new CPV-2a with the previous CPV-2a reported from Thailand, China, Uruguay, Vietnam, Singapore, and India. Interestingly, the current new CPV-2b in this study was not closely related to the previous CPV-2b reported in Thailand. The CPV-2c in this study was closer to Asian CPV-2c and further from either European or South America CPV-2c. Interestingly, FPV was identified in a diarrhea dog. The evolution of CPV in Thailand is very dynamic. Thus, it is important to monitor for CPV mutants and especially the clinical signs relating to these mutants to conduct surveillance for the emergence of new highly pathogenic CPV in the future. Keywords: canine parvoviruses, diversity, Thailand, VP2 gene.

This study aimed to predict the potential inflammation in lungs caused by exposure to methyl methacrylate (MMA; in silico study) and assess inflammation in lungs in response to MMA inhalation in mice (in vivo study). In silico and in vivo studies were performed using 24 mice divided into a control group (0 ppm MMA) and five treatment groups, which were exposed to 150 ppm MMA for 40, 80, 120, 160, and 200 min, respectively. Lung tissues were harvested and examined with a light microscope at 400×. In silico studies confirmed the existence of one activation bond between MMA and the toll-like receptor 4 (TLR- 4), namely, His 228, with a MolDock score of –43.677 kcal/mol. Microscopic examination of lungs confirmed that a greater number of inflammatory cells were found in the treatment group than in the control group and symptoms of inflammation were clearly observable after 120 min of exposure. Thus, inflammation occurring due to MMA interaction with TLR-4 receptors can be predicted in silico and exposure to 150 ppm MMA for more than 120 min can cause lung inflammation in mice. Keywords: inflammation, inhalation, in silico, methyl methacrylate.

Congenital anomalies of the urinary system are common affections in ruminants. Dilatation of the pelvic urethra is one of these affections in which the pelvic urethra dilated than normal diameter. This study aimed to explain the diagnosis and surgical treatment of urethral dilatation in cattle calves. Twenty-three bull calves (2-7 months old) were presented with a history of stranguria, tenesmus, and straining. Diagnosis of urethral dilatation was relied on the case history and clinical examination and was confirmed using survey and contrast radiography, ultrasonography, and biochemical tests. Treatment was done by urethrostomy under the effect of local infiltration analgesia. Physical examination revealed the presence of an oval, firm, and painless swelling at the perineal region, starting just below the anus and extended to the base of the scrotum. The owners reported that the initial swelling size and severity of symptoms increased with the progress of animal age. Biochemical findings revealed non-significant changes in blood urea nitrogen and creatinine levels. Radiographic findings showed an oval radiopaque mass. However, a well-demarcated structure with acoustic enhancement was detected on ultrasonographic examination. Urethrostomy resulted in a successful outcome of all cases. Depending on these findings, ultrasonography is the most reliable diagnostic tool and urethrostomy is the intervention of choice with acceptable results for diagnosis and treatment of urethral dilatation in cattle calves, respectively. Keywords: congenital anomalies, urethral dilatation, urethrostomy.

Houseflies (Musca domestica) are synanthropic insects which serve as biological or mechanical vectors for spreading multidrug-resistant bacteria responsible for many infectious diseases. This study aimed to detect antibiotic-resistant bacteria from houseflies, and to examine their resistance genes. A total of 140 houseflies were captured using sterile nylon net from seven places of Mymensingh city, Bangladesh. Immediately after collection, flies were transferred to a sterile zipper bag and brought to microbiology laboratory within 1 h. Three bacterial species were isolated from houseflies, based on cultural and molecular tests. After that, the isolates were subjected to antimicrobial susceptibility testing against commonly used antibiotics, by the disk diffusion method. Finally, the detection of antibiotic resistance genes tetA, tetB, mcr-3, mecA, and mecC was performed by a polymerase chain reaction. The most common isolates were Staphylococcus aureus (78.6%), Salmonella spp., (66.4%), and Escherichia coli (51.4%). These species of bacteria were recovered from 78.3% of isolates from the Mymensingh Medical College Hospital areas. Most of the isolates of the three bacterial species were resistant to erythromycin, tetracycline, penicillin and amoxicillin and were sensitive to ciprofloxacin, ceftriaxone, chloramphenicol, gentamicin, and azithromycin. Five antibiotic resistance genes of three bacteria were detected: tetA, tetB, mcr-3, and mecA were found in 37%, 20%, 20%, and 14% isolates, respectively, and no isolates were positive for mecC gene. S. aureus, Salmonella spp., and E. coli with genetically-mediated multiple antibiotic resistance are carried in houseflies in the Mymensingh region. Flies may, therefore, represent an important means of transmission of these antibiotic-resistant bacteria, with consequent risks to human and animal health. Keywords: antibiotic resistance genes, antibiotic-resistant bacteria, houseflies.

Salmonella spp. are an important group of pathogens responsible for human and animal diseases. This study aimed to estimate the prevalence and identify and characterize of Salmonella spp. isolated from broiler farms of Gazipur, Tangail, and Dhaka districts of Bangladesh. This study also evaluated the difference of Salmonella positivity status between two groups of farms, good practices adapted in broiler rearing at the project intervened farms, and non-project intervened traditional farms. A total of 352 samples including 128 cloacal swabs, 32 whole carcasses, 64 feed, 64 water, and 64 attendants' hand rinses were collected through convenient sampling technique from 16 poultry food safety project of Food and Agricultural Organization of United Nations Bangladesh intervened farms and other 16 non-project intervened farms in the same location. Various cultural based techniques and biochemical methods were employed for the estimation of prevalence, isolation, and identification of Salmonella spp. which was further evaluated by polymerase chain reaction. Antimicrobial susceptibility test using disk diffusion methods and serogrouping by slide agglutination test was accomplished for additional characterization. Among the samples, an overall prevalence of Salmonella spp. was 31.25% (110/352) (95% confidence interval [CI]=26.44-36.38%). However, the prevalence of Salmonella spp. was 24.43% (43/176) (95% CI=18.28-31.47) in project intervened farms and 38.07% (67/176) (95% CI=30.87-45.68%) in non-intervened farms. Among the 110 isolates, 31.82% (35/110) were fitted under serogroup B, and the rest of the isolates 75 (68.18%) under serogroup D. Of 110 isolates, 82.72%, 77.27%, 81.82%, and 79.09% were susceptible to ciprofloxacin, gentamycin, norfloxacin, and streptomycin, respectively. In addition, 81.82% and 80% isolates were resistant to erythromycin and tetracycline, respectively. Isolated Salmonella spp. presented moderate resistance to both amoxicillin and azithromycin. Alarmingly, 80.91% (89/110) isolates were shown to be multidrug-resistant Salmonella spp. The study has presented a significant variation of the prevalence of Salmonella spp. between project intervened and non-project intervened farms, and this indicates project intervened farms are comparatively safer than the non-intervened farms considering public health and food safety grounds. This research outcome also has highlighted a substantial proportion of poultry origin multidrug resistance Salmonella spp. is a potential source of public health hazards. In this regard, proper awareness creation and motivational activities on good agriculture practices in poultry rearing and maintaining good personal hygiene at the farmers' level are warranted through participatory training. Keywords: good agriculture practices, hygienic practices, multidrug resistance, poultry, Salmonella spp.

Taenia saginata hazardously affects human and animal health. The distribution of this disease is found almost all over the world. The study aimed to obtain epidemiological information concerning prevalence and the distribution of bovine cysticercosis in Bali and Nusa Tenggara, Indonesia. A total of 267 community-owned Bali cattle serum samples from the provinces of Bali, West Nusa Tenggara, and East Nusa Tenggara were examined. The study was conducted by examining the serum of Bali cattle using enzyme-linked immunosorbent assay technique. Risk factors related to cysticercosis that analyzed were sex, breeding type, age, physical condition, source of drinking water, pen condition, and latrine availability. Seven of 91 Bali cattle sera from all regencies/cities in Bali showed a positive result. Those positive sera were originated from Buleleng (1), Gianyar (2), Denpasar (2), and Klungkung (2). Meanwhile, four of 92 Bali cattle sera from West Nusa Tenggara and seven of 84 from East Nusa Tenggara occurred antibodies against T. saginata. We identified that two risk factors that influence the incidence of T. saginata infection in Bali cattle in Bali were the sex and the cattle breeding type. Through this research can be made a map of bovine cysticercosis in Bali cattle in Bali and Nusa Tenggara region. By mapping the disease, it is recommended that the animal health officers should be more accurate when conducting postmortem examination, especially on cattle from a positive region. Keywords: Bali cattle, bovine cysticercosis, risk factor, Taenia saginata.

Escherichia coli can cause a number of serious infections both in human and veterinary medicine. Their management is increasingly complicated by the emergence and dissemination of multiresistance to various first-line antimicrobial agents. This study aimed to evaluate the resistance level to the commonly used antibiotics, with a focus on the first-line antimicrobial agents, in E. coli strains isolated from poultry in Western Algeria. E. coli culture was done on MacConkey agar and their identification was determined by AP20E system. For susceptibility testing, disk diffusion method to 14 antimicrobials, including first-line antibiotics, was used according to Kirby–Bauer disk diffusion method in Mueller-Hinton agar and the results were interpreted according to the Clinical and Laboratory Standards Institute guidelines. E. coli isolates were considered as multidrug resistance (MDR) when found resistant to at least one antimicrobial agent of three different families of antibiotics. Double-disk synergy and combination disk tests were used for initial screening and confirmation for extended-spectrum β-lactamases (ESBLs) production, respectively. A total of 145 E. coli strains were isolated in this study. High resistance levels to various antibiotics, including commonly used first-line antimicrobial agents, were recorded in this study. The highest resistance level was observed against nalidixic acid (90.34%, n=131), followed by tetracycline (86.89%, n=126), ampicillin (82.75%, n=120), enrofloxacin (80.68%, n=117) and neomycin (80.68%, n=117), trimethoprim/sulfamethoxazole (73.79%, n=107), norfloxacin (72.41%, n=105) and cephalothin (72.41%, n=105), amoxicillin/clavulanic acid (51.72%, n=75), chloramphenicol (22.75%, n=33), nitrofurantoin (17.24%, n=25), gentamicin (13.10%, n=19), and ceftiofur (3.44%, n=5). Moreover, resistance to multiple first-line antibiotics was also demonstrated in the present study. Overall, 139 out of 145 isolates (95.86%) demonstrated MDR (resistant to at least three antibiotics). In addition, five E. coli isolates (3.44%) were confirmed to be ESBL producers. The alarming rate of E. coli resistant to multiple first-line antibiotics in poultry demands intensified surveillance. These results call for taking drastic measures to preserve antibiotic effectiveness and reduce the emergence risks of extensively drug-resistant and pandrug-resistant E. coli isolates. Keywords: Algeria, Escherichia coli, extended-spectrum β-lactamases, first-line antibiotics, multidrug resistance, poultry.

The purpose of this research was to use environmental variables for predicting the probability of Hemiscorpius lepturus existence in the provinces where situated in the west of the Zagros Mountains. In this study, 64 occurrence records of the H. lepturus were extracted from the published documents available in electronic databases. MaxEnt model was used for predicting the ecological niches of this species. Normalized difference vegetation index (NDVI) and 19 climatic variables were used as the environmental variables affecting the distribution of this scorpion. The Jackknife test in the model was used to indicate the importance of variables to predict the probability of the presence of the studied species. The logistic threshold that was evaluated using a logistic regression algorithm showed the converting of the probability model into a binary model. The model was evaluated by area under the curve (AUC). The probability presence map of this scorpion was then prepared in ArcGIS 10.5 Software. The results of the analysis showed that the most important environmental factor on the distribution of H. lepturus was the maximum temperature of the warmest month (Bio5) with a contribution rate of 43% and permutation importance of 8%. The Jackknife test revealed that NDVI did not gain any value when it used independently in the model. The logistic threshold was reported 0.255 for the maximum test sensitivity plus specificity. The AUC of the model was 0.7698, shows an acceptable value for model validity. Overall the hot spots for this toxic scorpion seem to be in Khuzestan, Lorestan, and Ilam Provinces of the studied area. Regarding our findings, MaxEnt algorithm, in combination with geographic information system contributed to revealing the effects of environmental variables on the probability of H. lepturus presence in the west of Zagros Mountains. These visualized maps as a warning alarm can be helpful to policymakers for managing, controlling, and monitoring the scorpionism in high-risk areas. Keywords: ecological niches, Hemiscorpius lepturus, Iran, MaxEnt, Zagros mountains.

Edible bird's nest (EBN) is the nutrient-rich salivary bioproduct produced by swiftlets in Southeast Asia. Currently, researchers are exploring the therapeutic effects of EBN, such as cell growth promotion, antioxidant content, antiviral effects, bone strengthening, eyes care, and neuroprotection bioactivities. The therapeutic effects of EBN have been studied through different extraction methods but the metabolites profile of the EBN in each extract has not yet been elucidated. This study aimed to profile the water-soluble metabolites of EBN prepared in different extraction methods. Subsequently, an extraction method will be selected as an ideal extraction method for untargeted metabolite profiling on the water-soluble metabolites in EBN. In this study, water-soluble metabolites of EBN extracted by the four extraction methods were subjected to metabolite profiling through liquid chromatography-mass spectrometry (LC-MS). The extraction methods were acid extraction(ABN), pancreatic extraction (EzBN), eHMG extraction, and spray drying of HMG extraction (pHMG). The metabolite profiles, such as the number of metabolites and their identities in each extraction method, were evaluated through LC-MS analysis. The identity of metabolites present in the four extraction methods is inconsistent. Based on LC-MS analysis, only one and six metabolites were extracted differently through EzBN and ABN, respectively, in the first pre-screening. Through the second LC-MS screening on pHMG and eHMG extraction methods, eHMG was selected as an ideal extraction method due to the highest numbers of water-soluble metabolites with an amount of 193 was detected. Besides, eHMG extraction method was able to extract sialic acid and a high percentage of secondary metabolites. This study suggests that eHMG is the ideal extraction method for extracting higher number of water-soluble metabolites from EBN and could be further developed as an extraction method for industry application. In addition, this study also has identified the types of primary and secondary metabolites present in EBN. Keywords: edible bird's nest, extraction method, liquid chromatography-mass spectrometry, untargeted metabolite profiling.

This study was undertaken to isolate Listeria (L.) species from raw meats sold in markets in Enugu State, Southeast Nigeria, and to determine the antibacterial resistance profile. Twenty-five grams of beef (n=144), chicken meat (n=144), and pork (n=144) were collected randomly from supermarkets and general markets in Enugu State. Isolation of Listeria was done using half and full Fraser broths, and polymyxin acriflavine lithium chloride ceftazidime aesculin mannitol agar. Identification of isolates was done using an analytical profile index kit specific for Listeria. Confirmation of the genus Listeria was done by a polymerase chain reaction. The resistance of the isolates was determined using the disk diffusion method. Listeria was isolated from 39/144 (27.1%) chicken meat, 19/144 (13.2%) pork, and 66/144 (45.8%) beef samples cultured. Listeria innocua was the predominant species in chicken meat (52.6%) and beef (81.8%) samples. Listeria grayi, Listeria welshimeri, and Listeria ivanovii were also isolated from the beef and chicken meat samples. More than 65% of the isolates were resistant to penicillin, rifampicin, ciprofloxacin, sulfamethoxazole-trimethoprim, and cephalothin. All the isolates from beef and pork samples and 23 (92%) from chicken meat samples, were resistant to ≥3 classes of antibacterial agents. Mean multiple antibiotic resistance index (MARI) was 0.77 (range=0.42-1.00), 0.58 (range=0.25-0.83), and 0.79 (range=0.58-0.92) for the isolates from beef, chicken meat, and pork samples, respectively. All the isolates had MARI >0.2. Multidrug-resistant Listeria strains contaminate raw beef, pork, and chicken meats marketed in Enugu State, Southeast Nigeria. Keywords: antibacterial resistance, beef, chicken meat, Listeria species, pork.

This study aimed to detect and characterize current genotypes of canine parvovirus (CPV) in Egypt during 2018. A total of 50 fecal swabs were collected from clinically infected domestic dogs of 2-5 months of age, suspected to suffer from CPV infection, from Cairo and Giza Governorates. The samples were subjected to qualitative antigen detection using the rapid test, followed by isolation on Madin-Darby Canine Kidney (MDCK) cells, molecular characterization with partial amplification of VP2 gene using polymerase chain reaction (PCR), followed by sequencing and phylogenetic analysis. Out of 50 fecal samples, 20 samples were positive (40%) by Rapid CPV/canine coronavirus Ag Test Kit. These positive samples were cultured successfully on MDCK cells. Nine randomly chosen samples out of 30 apparently negative samples were amplified using PCR with primers Hfor and Hrev to yield a typical 630 bp fragment. Then, six randomly chosen samples out of nine were amplified using PCR with primers Pbs and Pbas to yield a typical 427 bp fragment. Sequencing, BLAST analysis and assembly of the two fragments (630 bp and 427 bp) to produce 912 bp fragments, in the six samples, revealed two serotypes CPV-2b and CPV-2c. The obtained strains were submitted to GenBank and given accession numbers MK642272, MK642273, MK642274, MK642275, MK642276, and MK642277. Phylogenetic analysis of the Egyptian strains serotype 2b illustrated that they were closely related to Thailand strains (accession numbers KP715709, KP715694, KP715701, and KP715700); while Egyptian strains serotype 2c was closely related to Thailand strains (accession numbers MH711894 and MH711902), Taiwanese strain (KU244254), Chinese strain (MF467242), and Vietnamese strain (accession number LC216910). The current research recommends further epidemiological studies to assess the extent of the occurrence of different serotypes of CPV in Egypt and the efficiency of imported and locally produced vaccines in protection against CPV infection. Keywords: canine parvovirus, Egypt, genotyping, phylogenetic analysis, serotyping.

Ruminant flukes, including Fasciola spp. and Paramphistomum spp., are recognized as the significant parasites in livestock worldwide. Cattle infected by these fluke results in slower growth rate and productivity losses contributing to economic losses. In case of Fasciola spp., the parasite is considered as an important zoonotic parasite. This study aimed to investigate the prevalence of fluke invasion in beef cattle around Phayao Lake, Phayao, Thailand, between January 2019 and June 2019. A total of 311 fecal samples from beef cows reared nearby Phayao Lake were examined for the presence of fluke eggs by formalin-ethyl acetate sedimentation and subsequently identified by morphology together with methylene blue staining. The overall prevalence of fluke invasion in beef cattle around Phayao Lake was 33.8% (105/311). The prevalence of rumen fluke and liver fluke was 25.4% (79/311) and 8.4% (26/311), respectively. Mixed infection of both species was found at 1.9% (6/311). Age of cattle was observed to be associated with invasion rate of all flukes, particularly in the ages over 4 years, which was the highest group of invasion. However, other risk factors, including gender, breed, and location of animals, were not found to be related. This study provides the current status of natural fluke invasion among the beef cattle in Phayao, Thailand, which could be critical for designing the control program of these parasites. Keywords: beef cattle, digenetic trematodes, Fasciola spp., Paramphistomum spp., Phayao Lake.

Helminth infections are one of the greatest causes of productive and reproductive loss in animals and man, and in some cases, it results in heavy mortalities. This study was conducted to determine the prevalence, species diversity, patterns of infections and risk factors associated with helminth infections of cattle in Ilorin, Nigeria. A total of 478 fecal samples were collected from abattoirs and cattle farms over a year period (March, 2018-February, 2019). Fecal samples were visually examined then observed using simple flotation and formalin-ethyl acetate sedimentation techniques. Eggs and worms were identified according to standard procedures. The packed cell volume was determined using the hematocrit centrifugation technique. A total of 79.92% of the cattle examined were found positive with one or more helminth species. Eighteen helminth species (cutting across all classes of helminths) were detected, with Haemonchus contortus (60.46%), Trichostrongylus spp. (46.44%), Ostertagia ostertagi (42.05%), Bunostomum phlebotomum (28.87%), Cooperia spp. (24.27%), Oesophagostomum radiatum (21.97%), Strongyloides papillosus (12.13%), and Fasciola gigantica (10.67%) been the most prevalent. Helminth infection was detected all through the year with the least prevalence recorded in February (55.00%). About 61% of the examined cattle harbored double/multiple helminth species. There was a significant difference between breed, sex, physiological status, and season with the prevalence rate of helminth infections (p<0.05). Our investigation demonstrated high prevalence and wide diversity of helminth species, which suggests that helminth infections are of great concern among cattle in Ilorin and Nigeria in general. There is a need for a radical veterinary intervention to curb the menace so as to have an economically robust cattle industry in Nigeria. Keywords: cattle, helminths, Nigeria, prevalence, risk factors.

Fermented milk can be used to produce antihypertensive peptides. Lactic acid bacteria (LAB) with its proteolytic system hydrolyze milk protein during fermentation to produce several peptides, which include antihypertensive bioactive peptides. This study aimed to investigate the ability of indigenous LAB for the production of angiotensin-I-converting enzyme inhibitory (ACE-I) peptides in fermented milk and to characterize the ACEI peptides. Reconstituted milk (11%) inoculated with ten LAB isolates, and then incubated at 37°C until it reaches pH 4.6. The evaluation was carried out for LAB count, lactic acid concentration, peptide content, and ACE-I activity. The low molecular weight (MW) peptides (<3 kDa) were identified using Nano LC Ultimate 3000 series system Tandem Q Exactive Plus Orbitrap high-resolution mass spectrometry. The result showed that the ten LAB isolates were able to produce ACE-I in fermented milk with the activities in the range of 22.78±2.55-57.36±5.40%. The activity of ACE-I above 50% produced by Lactobacillus delbrueckii BD7, Lactococcus lactis ssp. lactis BD17, and Lactobacillus kefiri YK4 and JK17, with the highest activity of ACE-I produced by L. kefiri YK4 (IC50 0.261 mg/mL) and L. kefiri JK17 (IC50 0.308 mg/mL). Results of peptide identification showed that L. kefiri YK 4 could release as many as 1329, while L. kefiri JK 17 could release 174 peptides. The peptides produced were 95% derived from casein. The other peptides were from α-lactalbumin, β-lactoglobulin, and serum amyloid A. The peptides produced consisted of 6-19 amino acid residues, with MWs of 634-2079 Dalton and detected at 317-1093 m/z. A total of 30 peptides have been recognized based on literature searches as ACE-I peptides (sequence similarity: 100%). L. kefiri YK4 and JK17 are the potential to be used as starter cultures to produce the bioactive peptide as ACE-I in fermented milk. Keywords: angiotensin-I-converting enzyme inhibitory peptides, fermented milk, indigenous lactic acid bacteria, Lactobacillus kefiri.

Glucagon plays a significant role in glucose homeostasis by controlling hepatic glucose output in terms of both hypoglycemic and normoglycemic conditions. This study aimed to determine the amount and intensity of insulin and glucagon in addition to estimating the relationship between α- and β-cells for two animals, camel and buffalo. Twenty fresh pancreas samples were collected from 10 buffalo and 10 camel adults immediately after slaughter from AL-Kut abattoir, Al- Kut, Iraq. Hematoxylin and eosin staining technique and the immunohistochemistry technique were used. The histological results, for both animals, showed the cells of the pancreatic islet could be differentiated from the exocrine cells by their paler appearance. The pancreatic islets were round, oval, and irregular shaped. In the camel, the pancreatic islets had a larger diameter than that in the buffalo. The average diameter of β-cells and their percentage was higher than those of the α-cells in the camel. In the buffalo, glucagon-immunoreactive cells were found in abundance with high intensity, whereas insulin-immunoreactive cells were more prominent with high intensity in the camel. In both animals, the α-cells and glucagon-immunoreactive cells were distributed on the peripheries of the pancreatic islets, whereas the β-cells were distributed throughout the pancreatic islets. The study inferences that these differences may be due to the differences in the environment of the animals which affect the structures of body organs. Keywords: buffalo, camel, glucagon, immunohistochemical, insulin, pancreas.

Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli are gradually increasing worldwide and carry a serious public threat. This study aimed to determine the antimicrobial resistance pattern of ESBL-producing E. coli isolated from fecal samples of piglets and pig farm workers. Fecal samples from <3-month-old piglets (n=156) and farm workers (n=21) were processed for the isolation of ESBL-producing E. coli in MacConkey agar added with 1 μg/mL of cefotaxime. E. coli (piglets=124; farm workers=21) were tested for ESBL production by combined disk method and ESBL E-strip test. Each of the ESBL-positive isolate was subjected to antibiotic susceptibility testing. The ESBL-producing E. coli were further processed for genotypic confirmation to CTX-M gene. A total of 55 (44.4%, 55/124) and nine (42.9%, 9/21) ESBL-producing E. coli were isolated from piglets and farm workers, respectively. Antibiotic susceptibility testing of the ESBL-positive E. coli isolates from piglets and farm workers showed 100% resistance to ceftazidime, cefotaxime, cefotaxime/clavulanic acid, ceftazidime/clavulanic acid, and cefpodoxime. A proportion of 100% (55/55) and 88.9% (8/9) ESBL-positive E. coli were multidrug resistance (MDR) in piglets and farm workers, respectively. On genotypic screening of the ESBL E. coli isolated from piglets (n=55), 15 were positive for the blaCTX-M gene and of the nine ESBL E. coli from farm workers, none were positive for the blaCTX-M gene. Although there was no significant difference in isolation of ESBL-producing E. coli between piglets and farm workers, the ESBL-positive E. coli from piglets showed relatively higher MDR than farm workers.

Brucellosis is a zoonotic disease caused by the bacterium of the genus Brucella. This disease is present worldwide, especially in developing and underdeveloped countries, where it is endemic. This first-of-its-kind study in Lebanon aimed to assess the prevalence of brucellosis across the country and to determine the efficacy of a vaccine for reducing losses in herds so that its toll on public health is reduced. Three hundred and fifty-three blood serum and 261 milk samples were obtained from cows in different areas of Lebanon. The samples were analyzed using serological tests (rose Bengal, milk ring, and indirect enzyme-linked immunosorbent assay [ELISA]) and confirmed with competitive ELISA and polymerase chain reaction. The highest rate of Brucellae was found in the Bekaa region (10%). After vaccination of 5 cows and 13 heifers at different times, the results showed that all the vaccinated animals have developed an immune response to brucellosis 60 days after vaccination. This vaccine can be considered as stable and preventative to protect against brucellosis in animals and thus protect the public from this infection. These findings will provide further insight into designing future targeted awareness interventions and adapted policies as efforts toward reducing the prevalence and prevention of brucellosis in cattle in Lebanon. Keywords: Brucella abortus and melitensis, brucellosis, public health, vaccines, zoonosis.

Ciguatera fish poisoning (CFP) is a multisystem toxicosis caused by the ingestion of warm water marine species. Dogs and cats are susceptible to CFP, but there is little published and much unknown about the condition in these species. This study aims to describe the syndrome of CFP in dogs and cats and to develop a case definition. Six years (March 2011-February 2017) of medical records from the Esther Honey Foundation Animal Clinic (the only veterinary clinic in the Cook Islands during the study period) were reviewed to identify cases of CFP. Data relating to exposure history and clinical signs were collected. Two hundred forty-six cases of CFP were identified, comprising 165 dogs and 81 cats. Fish ingestion was documented in 29% of cases. Reef/lagoon fish and moray eels were most commonly implicated. The toxicosis was characterized by motor dysfunction with a high frequency of ataxia and paresis/paralysis/recumbency. Respiratory and gastrointestinal systems were also affected, especially in canine CFP cases. A multi-tiered case definition and a diagnostic algorithm for CFP in dogs and cats were developed based upon the findings of this study and a review of the existing literature. This case series is the largest study of canine and feline CFP to date. It documents the exposure history of cases and describes in detail clinical signs of the toxicosis. It also proposes a system of case classification that has the potential to both assist the diagnosis of CFP and facilitate future surveillance and research activities. Keywords: case definition, cats, ciguatera, clinical signs, Cook Islands, dogs, exposure.

This study aimed to characterize sheeppox virus (SPPV) using the P32 gene of the Capripoxvirus (CaPVs). Clinical samples of skin, scabs, and nasal swab from suspected outbreaks Horalagallu (n=13) and Gerahalli (n=11) at Ramanagara district in Karnataka were collected. All the samples were initially subjected to genus-specific diagnostic polymerase chain reaction (PCR). The pooled clinical samples from each outbreak were also subjected to virus isolation. The isolates were confirmed by CaPVs genotyping PCR targeting the full-length P32 gene, followed by sequencing and phylogenetic analysis. The clinical signs and lesions varied from mild to severe degree with no specificity between age and sex. Specific cytopathic changes in cell morphology were observed in infected Vero cells from both outbreaks, which were confirmed by PCR. The complete P32 gene from two outbreaks was successfully amplified with the expected amplicon size of 1006bp. The sequencing and phylogenetic analysis revealed that both the outbreaks were due to SPPV and shared high similarity with published SPPVs from Karnataka and other parts of India. The current study showed that complete P32 gene-based genotypic PCR assay can be used for genetic characterization and molecular epidemiology of both sheeppox and goatpox diseases and also to differentiate the causative agents. The sequence analysis revealed 100% similarity among the two outbreak isolates suggesting the same strain of the virus and common source of infection for the outbreaks. Keywords: goatpox, P32, polymerase chain reaction, phylogenetic analysis, sheeppox.

The study investigated the effect of feeding fermented mixture of cassava pulp and Moringa oleifera leaf meal (FCPMO) on the immune responses, antioxidative status, biochemical parameters, and intestinal ecology of broiler chickens. Four hundred Lohmann broiler chickens were distributed to four groups of diets including CONT (corn-soybean-based feed with no additive), BACI (corn-soybean-based diet supplemented with 0.1% zinc bacitracin), FERM (diet containing 20% FCPMO), and FERB (diet containing 20% FCPMO and added with 0.1% Bacillus subtilis). At days 4, 14, and 19, the chicks were vaccinated using commercial Newcastle disease-infectious bursal disease (ND-IBD), IBD, and ND vaccines, respectively. At day 35, blood was sampled and digesta was obtained from the ileum and caecum. Furthermore, the duodenal segment was obtained. The BACI, FERM, and FERB groups had higher (p<0.05) serum superoxide dismutase activity than control. The malondialdehyde was lower (p=0.07) in BACI, FERM, and FERB than that in CONT. The BACI and FERM had lower (p<0.05) leukocytes and lymphocytes than CONT. The hemoglobin, erythrocytes, and hematocrit were lower (p<0.05) in BACI and FERM than those in CONT and FERB. Serum total triglyceride was lower (p<0.05) in FERM and FERB than that in CONT. The FERM and FERB had higher (p<0.05) albumin levels. Serum globulin level was lower (p<0.05) in FERB than that in BACI, but did not differ from that in CONT and FERM. The numbers of coliform, lactose-negative enterobacteria and enterobacteria were lower (p<0.05) in FERB than that in other treatment groups. Crypt depth (CD) was higher (p<0.05) in FERM, while the villi height to CD ratio was lower (p<0.05) in FERM than that in CONT and FERB. The treatments showed no effect (p>0.05) on cecal volatile fatty acids production. Feeding FCPMO improved immune responses, antioxidative status, and physiological conditions, but had less effect on the intestinal ecology of broilers.
