The avian-pathogenic E. coli strains virulence methods have searched constantly which had been shown to be multifactorial and specific properties of virulent bacteria were associated with isolated samples from highly infected avian cases. On this observe a complete of 10 isolates of E. coli from chicken flocks IRAQ sources with respiratory problems instances had been tested by PCR test to diagnose the existence of genes liable of the serum-resistant (iss), fimbrial adhesion (felA), colicin manufacturing (cvaC), temperature-sensitive hemagglutinin (Tsh), aerobactin (iutA) ,and K1 and K5 antigens of capsul (kpsII). The iss gene had been discovered in 0% of strains, felA in 0%, cvaC in 30%, tsh in 80 %, iutA in 100 %, and kpsII in 0%.
