Online Published on 20 June, 2023. Abstract Respiratory infections are among the leading cause of production losses and mortality in small ruminants. Retroviral diseases (maedi, ovine pulmonary adenocarcinoma) in small ruminants are usually chronic in nature and remain unnoticed till clinical signs appear. In present study, the mixed infections of the MVV with JSRV and mycoplasma were investigated. Representative lungs tissues from a total of 136 animals were collected from Rajasthan and Uttar Pradesh and processed for histopathological evaluation and detection of the mixed infections of MVV, JSRV and mycoplasma. Histopathology revealed interstitial pneumonia (41.18%) as the most prominent type of pneumonia followed by broncho-interstitial pneumonia (31.61%) and acute bronchopneumonia (1.47%). Co-infection of MVV with JSRV was detected in 5 animals. Mixed infection of MVV and mycoplasma was observed in 7 animals. In conclusion, the co-infection of MVV with JSRV and mycoplasma exist in the small ruminants and studies are needed to the association of different respiratory pathogens in causation of pneumonia.
