A study was conducted to determine the distribution of E. coli in visceral organs of clinically sick chickens (Gallus gallus). A total of 24 tissue samples consisting of 6 liver, 12 small intestine, and 6 large intestine samples were aseptically collected from 12 fowls of 4 selected poultry farms of Ajmer suspected for colibacillosis and subjected to bacteriology and biochemical examination. 24 E. coli isolates were isolated following standard procedures. Processed tissue from each sample was cultured primarily on Brain Heart Infusion (BHI) broth and then secondarily on 7% defibrinated sheep blood (Blood Agar) and MacConkey agar. Presumptive colonies of bacterial agents on media plates were subjected to conventional biochemical characterization. The result of biochemical test identified the E. coli isolates from the samples of clinically sick chickens, almost 100%. The overall prevalence of E. coli was 100% and high rate of infection.
