Aim: The aim was to determine the prevalence and evaluation of antibiotic resistance pattern and minimum inhibitory concentration (MIC) of Campylobacter species isolated from foods of animal origin.
Materials and Methods: A total of 280 samples (comprising 150 chicken meat, 50 chevon and 80 milk) were collected from retail meat markets, slaughter houses and dairy farms and analyzed for isolation of Campylobacter species. A total of 29 isolates comprising 23Campylobacter jejuni and 6 Campylobacter coli were recovered, characterized biochemically and confirmed by polymerase chain reaction. These isolates were then tested for antibiotic resistance pattern through disc diffusion method, and MIC was assessed by MIC strips. The antibiotic resistance assessment was performed against 8 antibiotics viz. ampicillin, co-trimoxazole, erythromycin, levofloxacin, gentamicin, ciprofloxacin, ceftriaxone, and norfloxacin.
Results: The prevalence of Campylobacter spp. in chicken meat, chevon and milk samples were observed 17.33%, 6% and 0%, respectively. All the isolates were resistant to co-trimoxazole but sensitive to erythromycin. All the isolates showed different resistance pattern for the rest of the antibiotics. MIC results revealed that all the isolates were within prescribed concentrations for sensitivity for the antibiotics tested.
Conclusions: The foods of animal origin are source of Campylobacter infections to human beings. Thus, the development of antibiotic-resistant strains emphasizes the requirement of better surveillance and monitoring of the foods of animal origin and the use of antimicrobials in veterinary and human medicine require careful regulation.
