Description Respiratory diseases causing pneumonia are the 2nd leading cause of mortality in bovine calves and are primarily caused by viral pathogens. The present study was undertaken in cattle calves under twelve months of age for detecting four respiratory viruses, viz. bovine herpes virus-1 (BoHV-1), bovine viral diarrhoea virus (BVDV), bovine respiratory syncytial virus (BRSV), and bovine parainfluenza virus type 3 (BPI3), using a commercially available multiscreen antigen ELISA kit. A total of 30 cattle calves necropsied at the Department of Veterinary Pathology, DGCN COVAS, CSKHPKV, Palampur, from June 2021 to June 2022 were screened. The samples of lung tissues and nasal turbinates were collected and stored at –20°C until further processing. The collected tissue samples were homogenised and processed as per the standard protocol. Among the 30 necropsied samples, BoHV-1 and BRSV were detected in 17/30 (56.67%) samples, BPI3 was detected in 14/30 (46.67%) samples, and BVDV was detected in 8/30 (26.67%) samples. 5/30 (16.67%) samples were found positive for all four viruses. Moreover, three viruses were concurrently detected in 4/30 samples (13.33%), and two viruses were present in 10/30 samples (33.33%). Additionally, a single virus was detected in 4/30 samples (13.33%). In conclusion, the present investigation reveals the substantial presence of respiratory viruses in the respiratory tract of cattle calves. The result indicates a complex pattern of co-infections of different viruses, emphasising the need for effective surveillance and management strategies to address the diverse viral dynamics affecting bovine respiratory health.
