Campylobacter occurrence and antimicrobial resistance in samples from ceca of commercial turkeys and quails in Tehran, Iran


Sara Mirzaie*, Mohammad Hassanzadeh, Mohsen Bashashati and Abbas Barrin

Infected poultry is considered as the main source for transferring Campylobacter spp. to humans. Several studies have been carried out to determine the prevalence of Campylobacter infection and antimicrobial resistance rate of the isolates in broiler chickens, but related information regarding other meat producing birds, such as turkeys and quails is lacking in Iran. A total of 125 samples (75 turkeys and 50 quails) were collected from April to September 2010 and examined for Campylobacter spp. A total of 52 (41.6%) Campylobacter strains consisting of 41 and 11 isolates of turkeys and quails (54.6 and 22% infection rate) were isolated respectively. All of the isolated Campylobacter spp. from quails and 19.5% of turkey isolates were Campylobacter jejuni, while other isolates of turkeys were identified as Campylobacter coli. Susceptibilities of 52 isolates were determined for eight antimicrobial drugs by using the disk diffusion assay. Highest resistance rate was seen against ampicillin (84.6%), followed by resistance to tetracycline (69.2%), ciprofloxacin (50%) and nalidixic acid (34.6%). All of nalidixic acid resistant isolates were identified as C. jejuni by hippurate test. Quail C. jejuni strains unlike turkey isolates showed resistance to neomycin. None of the isolates were resistant to erythromycin, chloramphenicol and gentamicin.
