Eighty samples from enlarged congested kidneys were collected from freshly dead chickens from different farms of Assiut Governorate(and didn't suffer from any ration problems). These samples were taken to isolate some bacteria which affect kidneys., the isolation revealed presence of 8 organisms: E.coli at a rate of (70%) – Staph. aureus (37.5%) – Corynebacterium (31.3%) – Klebsiella (15%) – Proteus (18.8%) – Pseudomonas (11.3%) – Clostridium perfringenes (8.8%) – Enterococcus faec, huddling together and couldn't move. Postmortem examination revealed congestion and enlargement of kidneys, liver and spleen and the ureters were filled with urate. Birds which inoculated orally, didn't show any clinical signs. 21 days postinoculation all birds were sacrified, P.M examination revealed congestion and enlargement of kidneys and the ureters were distended with urate. Some birds formed stones in the ureters. Reisolation of the 2 organisms from kidneys of experimentally infected birds was successful. Histopatho, gentamycin and trimethoprim are the most effective drugs for E.coli while erythromycin, rifampin and gentamycin are the most effective for Corynebacterium
