|Abstract||The fluorescent antibody technique or horse-radish peroxidase labelled antibodies demonstrated parainfluenza-3 virus in nasal touch preparation and in sections of the nasal and tracheal mucosa and lungs within the first seven days after experimental intratracheal infection. Bovine foetal organ cultures gave better isolation of PI-3 virus than established bovine foetal cell lines. Bovine rhinotracheitis virus was isolated in foetal cell and organ cultures at 3, 7 and 11 days after experimental infection. PI-3 and IBR virus in mixed infections were demonstrated by electron microscopy using negative staining..|
