Identification of Escherichia coli O157 in sheep and goats using

Abstract: A total of 41 sorbitol non fermentative E. coli from previous work were used in this study. Among these isolates 5 were positive serologically by anti-O157 serum. All isolates were tested by PCR technique. No E. coli O157 were detected in all isolates by PCR. The results revealed that gene based method such as PCR technique is more reliable than biochemical and serological tests for diagnosis of E. coli O157
