| Abstract | ||||
| Two-hundred random samples of raw milk: pasteurized milk; Damietta cheese and plain yoghurt (50 sample each) were collected from dairy shops and supermarkets in Mansoura city, Egypt, and tested bacteriologically for the presence of Yersinia enterocolitica using two different methods for isolation procedure. Of 200 samples tested, 21 (10.5%) were found to contain enterocolitica when used BOS without alkali treatment method compared with 26 (13%) samples when used BOS with alkali treatment method. The incidence of Y. enterocolitica by both methods from raw milk; pasteurized milk and plain yoghurt was 28% Vs 36% : 10 Vs 12% and 4% Vs 4% respectively, while Y. enterocolitica failed to be isolated from soft cheese using both methods. All Y. enterocolitica strains were Sensitive to Gentamycin and Chloramphenicol, while resistant to penicillin and ampicillin. All Strains varied in susceptibility to erythromycin, Neomycin, Colistin sulphate and Sulfamethoxazole-Trimethaprim (SXT). The public health importance of isolated organisms as well as the recommended hygienic measures have been discussed. | ||||
