Then biochemical tests were done. Then serological test for representative number of samples from every farm identifying O1, O26, O44, O55, O115, O119, O125, O146, O151 and 2 samples were untypable. The samples were sensitive to Norofloxacin with 80.7% and resistant to Ampicillin and Cefotaxime with 100%.The PCR for 4 gene ompA, stx1, stx2 and eaeA. | ||||
