Abstract
The study was applied on 175 random samples of milk and milk products collected from different shops (35 of each), at Kaliobia governorate, Egypt, for detection the propagation of Y. enterocoliticastrains in these samples, beside the phenotypic characterization and detection of some antibiotic resistant virulence genes in them.The results gained from these samples by bacteriological examination represent19 (10.9%) Y. enterocolitica biotypes 1Aand 1B only isolates from 175 samples, from milk and Kareish cheese samples (5/14.3% for each ),(4/11.4%)white cheese,(3/8.6%) ice cream, and(2/5.7%) from yoghurt samples.The antibiotic sensitivity profile showed that, the isolated Y. enterocoliticawere very high resistant for Penicillin-G followed by methicillin, ampicillin,oxytetracycline,amoxicillin, ampicillin, streptomycin and erythromycin. Meanwhile, they were highly sensitive to meropenem and norfloxacinfollowed by gentamycin,ciprofloxacin, cefotaximeand florphenicol. PCR declared thatblaTEM andtetAgenes were detected in all eight studied Y. enterocoliticaisolates. So, it was concluded that,the presence of antimicrobial resistant Y. enterocolitica strains in dairy products could be a public health concern for the consumers.
