Abstract: In a poultry farm, few cases of Escherichia coli (E. coli) infections in poultry birds was observed in all age group birds. It is characterized by sudden mortality at the rate of five percent in the first week and in adult birds also. Escherichia coli (E. coli) infection in birds causes heavy losses in its productivity due to its high mortality rate. First- week mortality in chicks caused serious problem to the poultry farmers. This organism causes various manifestations in poultry, including mushy chick disease (Septic omphalitis). The acute colibacillosis may lead to death, while sub-acute form may cause pericarditis, air sacculitis, Peri hepatitis and egg peritonitis. Based on specific lesions which are of pathognomonic importance, it was diagnosed as colibacillosis infection. This investigation describes the observation of Escherichia coli (E. coli) infection and associate changes in chicken.
