Isolation and determine antibiotic susceptibility of Campylobacter jejuni in poultry feces in kerman

Campylobacter spp are pathogenic for human and animals. They are transmitted from animals and animal products to human and cause diarrhea and systemic disease. Campylobacter jejuni is the main species and the most common human pathogen. The aim of this study is the isolation of Campylobacter jejuni from the poultry feces and determination of their antibiotic susceptibility pattern.
In this study, within 2 years, 600 poultry feces samples randomly were collected from Islamkish in kerman. Collected samples were from secome section of poultry. The feces containment were inoculated into campylobacter selective medium containing antibiotics and sheep blood agar and then were incubated in microaerophilic condition in 42 ºc. The resulted colonies were confirmed to the species level using diagnostic tests. Drug resistance pattern against three antibiotics including tetracycline, ampicillin and co-trimoxazole was determined by disk diffusion method.
Results and In this survey, 190 (31.66%) Campylobacter jejuni were isolated. Drug resistance pattern showed that the prevalence of resistance to tetracycline, ampicillin and co trimoxazole were 54%, 54, and 91%, respectively. Regarding to the results, Campylobacter jejuni isolated in this study in Kerman had been more resistant to co-trimoxazole.
