Abstract: In this study, bacteriological examinations were revealed of intestinal contents of 66 enterotoxaemia suspected cases for E.coli, Campylobacter spp. and Staphylococcus spp. These agent were found respectively; 30.3%, 6.1%, 3.0%. Bacteriological agent could not be isolated from 22.7% of these cases. Clinical cases of E.coli infections followed a systemic (70%) and an enteric form (30%). Macroscobic observations in E.coli systemic infections showed collection of curdled milk in abomasum and lesions in mesenteric lymph nodes. In the enteric form lesions were consentrated in the intestines. Also collection of curdled milk in the amomasum and kidney lesions were noted Campylobacter infections. Focal abcesses were recorded in Staphylococcus infections. In the microscopic examinations of E.coli infections, hepatic paranchymatosis, glomerulonephritis, acute interstitial pneumonia and acute catarrhal enteritis were prevalent. Necrotic enteritis and degeneratif changes in tubuler structures of kidney were recorded in Campylobacter spp. infections. Focal inflamatory lesions were prevalent in Staphylococcal infections.
