The study was designed to find out the probable disease conditions causing pneumoenteric lesions, based on gross and histopathological findings. During the present study, a total of 500 samples comprising of trachea, lungs and intestines were examined for the presence of either pneumonic or enteric lesions. A systematic screening of these samples revealed various pathological changes on gross and histopathological examinations. The results indicated 45.8 per cent pneumonic infections and 33.8 per cent enteric infections in the present study. The proportional disease specific prevalence of various pneumonic conditions of poultry in the present study revealed higher prevalence rate of pneumonia due to bacterial agents (46.29%), followed by miscellaneous agents (27.95%) and viral agents (25.76%). The proportional disease specific prevalence of various enteric infections of poultry in the present study indicated higher prevalence of parasitic enteritis (48.52%) when compared to bacterial (35.5%) and viral enteritis (15.98%).EnglishThesis
