A cross-sectional epidemiological study using a multistage sampling strategy in slaughter cattle in Mymensingh, Bangladesh was conducted during September 2001 to April 2002 to study distributions and risk factors of specific pulmonary lesions and diseases. The pulmonary lesions and diseases were diagnosed on the basis of macroscopic and microscopic pathological and parasitological findings. The frequency distribution of pulmonary lesions and diseases in slaughter cattle was found to vary among categories of the study variables. The risk factors identified on statistical basis were male cattle and ${leq}3$ years old cattle and summer in congestion, slightly thin physical condition and summer season in pulmonary emphysema, slightly thin physical condition in parasitic bronchitis as well as female cattle, autumn and rainy seasons in pulmonary hydatidosis. The population impact and etiologic significance of summer season on pulmonary congestion and emphysema was more important than that of adult male cattle. The population impact and etiologic significance of autumn season on pulmonary hydatidosis was more important than that of female cattle during rainy season. Population impact of slightly thin cattle on parasitic bronchitis was poor.
