A study was conducted to determine the incidence of diseases in various age groups of 10 different flocks of birds from 5 different poultry farms in some selected areas of Bangladesh. The diseases were diagnosed based on history,signs and symptoms prior to death,lesions observed after post mortem examination of dead birds and by bacteriological examinations. A total 8169 dead chickens (2960 chicks, 1083 grower and 4126 adults) were examined. Related samples like liver,spleen and intestine were collected and were cultured on different bacteriological agar media. Among bacterial diseases salmonellosis was found in 53.90% of chicks (group 1) followed by omphalitis in 28.42%, colibacillosis in 13.36%, mycoplasmosis in 2.55%, necrotic enteritis in 1.18% and infectious coryza in 0.59%. The bacterial diseases salmonellosis, colibacillosis, infectious coryza and necrotic enteritis were detected in 55.96, 11.93, 29.91 and 2.20% of group 2 (growers), respectively. Omphalitis disease was never found in grower. Mycoplasmosis was not found in group 2. Salmonellosis was found in 53.32% of adult chicken followed by mycoplasmosis in 39.09%, infectious coryza in 6.11% and necrotic enteritis in 1.48%. Omphalitis was also not found in this group. This group was also not affected by colibacillosis.
