There is no special trait for differentiation of Avian Pathogenic Escherichia coli from Avian Fecal Escherichia coli. This investigation is aimed, as a case control study, to evaluate and compare the frequency of iss and irp2 in 43 AFEC strains and also 40 and 56 E. coli strains isolated from the liver and kidney of chickens with colibacillosis, respectively, farmed in Zabol, as a border region of Iran, by PCR. 86.9% and 37.2% of isolates collected from chickens with colibacillosis and feces samples obtained from healthy chickens were positive for iss gene, respectively (P<0.05). On average, 59.3% of E. coli strains isolated from colibacillosis have irp2 gene while 27.9% of isolates from the feces of healthy birds were positive (P<0.05). 52.15% of isolates from colibacillosis and 19.62% of isolates from healthy chicken feces were positive for both genes, with statistical significant difference (p<0.05). This marked difference in the distribution of iss and irp2 genes makes these two genes good markers to differentiate AFEC and APEC strains especially in Sistan region to improve colibacillosis control measurements.
