Background: Bacterial infections causing digestive problems are among the most serious threats to Egypt's duck industry, owing their effects on feed utilization and body weight gain. Aim: As a result, goal of this study was identify bacterial pathogens enteritis in ducks as well testing antimicrobials resistance capabilities. Methods: Forty-two flocks from different localities at four Egyptian Governorates (EL-Sharkia, El-Gharbia, El-Dakahlia El-Qaliobia) have been subjected clinical postmortem examination isolation identification. The liver samples collected aseptically freshly euthanized for followed by identification using conventional biochemical tests, VITEK 2 system confirmatory PCR detection uid A gene (beta-glucuronidase enzyme) E. coli. In addition, antimicrobial sensitivity isolates against used. Results: Forty six positive were identified methods VITEK2 including Staphylococcus spp. (52.17%), Escherichia coli (41.30%), 2.17% each Enterococcus casseliflavus, Salmonella enterica subspecies arizonae Enterobacter cloacae. 556 bp. antibiogram patterns isolated naturally infected our work demonstrated 100% multi drug with varying results drugs tested. Such findings supported fact upgrading multidrug-resistance Staphylococci Enterobacteriacae. Conclusion: prevalent associated first report Egypt.
