الملخص EN

This study was conducted on 80 cases of damaged kidneys received by poultry disease diagnostic centers in Baghdad.

Four microorganisms were isolated E.coli, Proteus milabilis, Pseudomonas aregenosa and Klebsiella pneumonia and formed 55, 22.5, 17.5, and 5 % of the infection respectively.

While no any kind of bacteria were isolated from kidneys of healthy chicks.

To be sure the E.

coli could be a cause of kidney damage.

An experimental infection with E.coli was carried out on 40 chicks, three weeks old, and randomly divided into two groups.

Chicks of the first group was inoculated intravenously with 0.5 ml of field isolated E.

coli suspension containing 2 x 107 colony forming unit (CFU), while the second group was inoculated with 0.5 ml distilled water and considered as control group.

The results revealed that chicks inoculated with E.coli showed 70 % mortality rate with severely congested swollen kidneys with acute interstitial nephritis.

However, this study gave information on kidney damage widely spread at this time ; therefore, it could be recommended for other studies to be hold in the future on the other causative agents of each case.
