Abstract
The highest incidence of positive pathogenic E.COLI (APEC) isolated in this study was from chickens (57.96%) followed by ducks ,pigon, turkey ,ibis and quail with a percentage ,25.48%, 5.10%, 4.46%, 3.82% and 3.18% respectively. Heart , liver and lungs were the important tissues in production of APEC E.COLI O26 , O127, O55, O119, O111, O78, O86, O2 and O114 were the most prevalent serogroups identified in this study .using PCR five virulance associated genes in the APEC serogroups were irp2 , iron, ompt, iss and hlyf from all examined isolates . xperimental infection of broiler chickens with the different isolated E.coli serogroups ,o78 and o2 showed the highest mortality rates 60% and 50% respectively  with   severe reduction in the mean body weight from 20-30% . Antibiotic sensitivity of the isolated APEC was studied.
