The prevalence of Yersinia enterocolitica and other Yersinia species in meat and some edible offal of food animals [electronic resource].

Includes references.

The objective of this study was to investigate the prevalence of Y. enterocolitica and other Yersinia species in meat and some edible offal samples of food animals and to determine their susceptibilities to antimicrobial agents. For this purpose, a total of 90 random samples (30 each of meat, liver and kidney) were collected from 30 animals (10 each of cattle, sheep and camel) from local butcher's shops in Sharkia province, Egypt (traditionally slaughtered animals at Zagazig abattoir). The obtained results declared that Yersinia spp. were detected in 6 out of 30 (20%) cattle samples, 7 out of 30 (23.33%) sheep samples and from 7 (23.33%) of camel samples. Y.enterocolitica, Y.intermedia and Y.frederiksenii could be isolated and identified from the examined meat, liver and kidney of the examined animals with varying percentages. Antibiotic susceptibility analysis showed that there was no difference in the susceptibilities of the three Yersinia species isolated from the examined samples. The results revealed that no strains were resistant to ceftriaxone, cefuroxime, ciprofloxacine, gentamicin, kanamycin, neomycin or polymyxin. In contrast, there were high levels of resistance to ampicillin, penicillin, cefalothin and amoxicillin.
