Abstract:
The present work was carried with the aim to detect the verocytotoxigenic genes of E. coli at the Navsari. During the study a total of 210 meat samples were processed, which included 60 samples of chicken, and 50 samples each, of chevon, mutton and carabeef. A total of 51 were positive for E. coli. included 14,11,8 and 18 samples respectively in case of chicken, chevon, mutton and carabeef. All 51 E. coli (VTEC) isolates were subjected to molecular analysis of verocytotoxigenic genes stx 1 and stx2 and 9 (17.64%), 5 (9.8%) and 3 (5.8%), isolates contained stx 1, stx 2 and both stx 1as well as stx 2, respectively. Carabeef samples showed the highest occurrence (11.7%) followed by chicken (3.9%), chevon (3.9%) and mutton (1.9%). The stx 1 gene was more prevalent compared to stx 2 gene.
