Abstract
Aim: To determine the
carriage and antimicrobial resistance of Thermophilic
Campylobacter species in the gastrointestinal tracts of farm and
laboratory animals in Morogoro, Tanzania
Materials and Methods: Faecal samples were collected from
farm (n=244) and laboratory (n=466) animals and were subjected to
the Cape Town protocol for isolation of Campylobacter. Isolates
were preliminarily identified based on potassium hydroxide string
and hippurate hydrolysis tests. Polymerase chain reaction (PCR)
was employed for confirmation of isolates. Antimicrobial
resistance testing was done using disc diffusion method.
Results: Of the laboratory animals 26.7% of guinea pigs
(n=30) and 1.2% of rats (n=242) were colonized with Campylobacter.
Four isolates from guinea pigs were Campylobacter jejuni and the
other four were C. coli. From rats, two isolates were C. jejuni
and one was C. coli. In farm animals thermophilic Campylobacter
were detected from 31.6% of sheep (n=57) and 60% horses (n=5). Of
the isolates 12 (57%) were C. jejuni (10 from sheep and 2 from
horses) and the remaining were C. coli (8 from sheep and 1 from a
horse). The isolates were frequently resistant to erythromycin,
norfloxacin, colistin sulphate and nalidixic acid; whereas low
levels of resistance were observed for ciprofloxacin and
gentamicin.
Conclusion: Our study reveals carriage of antimicrobial
resistant thermophilic Campylobacter in the intestines of the
study animals. This highlights possibilities in involvement of
these animals in the epidemiology of Campylobacter infections.
Thus, there is a need to consider these animal species when
planning control measures for this zoonotic bacterium.
Keywords: campylobacteriosis, cape town protocol, farm
animals, laboratory animals.
