Abstract :

E. coli is one of the most important pathogenic agent affecting chickens which costs the poultry industry resulting into high economic losses due to increased mortality. During present study, mortality due to Colibacillosis in nine commercial chicken flocks belonging to Nagpur region of Maharashtra was noticed. Characteristic lesions perihepatitis, pericarditis, air saculitis and pneumonia were observed. Pink colonies on MLA, metallic sheen on EMB confirmed the E. coli infection. Clinical samples of liver collected from nine commercial chicken flocks were further con­firmed as E. coli. by PCR amplification of 500bp of ecp gene. Pathological lesions, cultural characteristics along with PCR amplification of ecp gene confirmed E. coli infection in commercial chickens.
