In the present study, 86 avian pathogenic E. coli isolates from chicken were subjected to multiplex PCR to detect the presence of virulence genes stx1, stx2, eaeA, and hlyA. Forty-seven isolates harbored one or more virulence genes, stx1, stx2, and eaeA while gene hlyA was not detected in any of the samples. Of these, 15 (17.44%) isolates harbored stx1gene, 11 (12.79%) isolates carried stx2 gene, 18 (20.93%) isolates were positive for both stx1 and stx2 genes and 3 (3.49%) isolates carried eaeA gene. |
