Abstract

Avian pathogenic E. coli (APEC) are responsible for significant economic losses in chicken industry, thus identification of VIRULENCE GENES and their prevalence can be helpful to preventative methods such as productions of vaccine. The pathogenicity of APEC strains is due to a variety of several virulence factors that expressed by several genes. In this study, 60 E.coli strains were selected from cases of avian colibacillosis in commercial broilers from Golestan province. DNA was extracted by boiling method and three important VIRULENCE GENES, iss, ompT and iroN, were detected by multiplex PCR. iss is one of the important gene in increased serum survival. iroN involves in iron acquisition mechanism and ompT encodes protease, which has been shown to cleave colicins. Prevalence of iss, ompT and iroN genes were detected in 38.3%, 43.3% and 40% of isolates respectively and 35% of isolates were positive for the presence of three genes altogether. With regard to final results and the existence of varieties in frequency of these genes in different parts of the world it concluded that virulence factors were different in different parts of the world because virulence factors are multifactorial phenomenon. It seems that these isolates are opportunistic E.coli and because of existence of predisposing factors they could cause disease in poultry.
