İstanbul’da Satışa Sunulan Piliç Etlerinde Termotolerant Campylobacter spp. Prevalansı ve Antibiyotik Dirençliliği

OpenAlex Türkçe

Campylobacter spp. are some of the mostcommon causes of bacterial diarrhea in humans worldwide. They are mainlyconsidered as foodborne pathogens that are found in raw or undercooked poultryand serve as an important source of sporadic campylobacteriosis. The present study was aimed to determine theprevalence and the antimicrobial resistance patterns of thermotolerant Campylobacter spp. in chicken meat. Atotal of 176 samples of chicken meat were analyzed using PCM and BAX®system. The samples analyzed included:56 samples of whole chicken, 27 samples of chicken breast, 33 samples ofchicken thigh, 25 samples of chicken drumstick and 35 samples of chicken wings.Samples of all the fresh chicken meat sold in İstanbul were randomly purchasedfrom different major supermarkets in their original, individual packages.Laboratory analyses to detect thermotolerant Campylobacter spp. wereperformed in accordance with the ISO 10272-1, 2006 standard (qualitative analysis).API® Campy (bioMerieux, Marcy-l’Etoile, France) was used for theconfirmation of presumptive colonies. Campylobacter isolates weresubjected to antimicrobial susceptibility tests by the disc diffusion method asrecommended by the National Committee for Clinical Laboratory Standards. Zonesof growth inhibition were evaluated according to the NCCLS standards. UsingPCM, the prevalence of C. coli, C. jejuni and C. lari was determined as 15.34, 8.52 and 1.7%, respectively.However, using BAX® system, the prevalence was determined as 15.90, 18.75 and1.7% for C. coli, C. jejuni and C. lari, respectively. C. coliwas resistant to nalidixic acid (78.57%), ofloxacin (14.29%) norfloxacin(10.71%) and ampicillin (10.71%). But the highest resistance was observed tonalidixic acid (90.91%) for C. jejuniand (100%) for C. lari. Inconclusion, considering the public health, chicken meat is a common source for Campylobacter strains and antibioticsshould be used carefully in veterinary medicine.
