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.

Salmonella spp are pathogenic for human or animals، which aquired by oral route. They are transmitted from animals and animal products to human، salmonella causes enteritis، systemic infection، and enteric fever. So the goal of this investigation is evaluation of Salmonella spp and medicine resistance pattern in poultry feces to tetracycline، ampicilline and cotrimoxazole in kerman city. In this survey، 1000 poultry feces samples were collected from a slam kish in kerman. Samples transmitted to microbiology Lab in selenit F for enrichment. Then samples cultured on SS agar and incubated in 37°c for 24 hours then، performed biochemical tests for identification Salmonella spp and 5. 6% (56/1000) were positive for among them. Then، drug resistance pattern was carried out with disc diffusion and agar dillusion method، to determination of MIC for tetracycline، ampicillin، cotrimoxazole. Results and In this study 56 Salmonella spp were isolated in this rigion. Drug resistance pattern to antibiotics such as tetracycline، ampicillin and cotrimoxazole were: 55. 3%، 7. 5%، 35. 7% with average MIC respectively: (MIC≥16µg/ml) (MIC ≥ 32µg/ml) (MIC ≥ 4. 76µg/ml) From 56 Salmonella spp which were isolated from this region، the most resistant was to tetracycline.
