Nasal cells extracted from nasal swabs obtained from 95 cattle with signs of respiratory disease, out of eleven different herds, were tested for BHV-1, PI-3 virus, BRSV and BVDV using direct immunofluorescence technique. Viral antigen positive samples were detected in seven out of eleven herds examined. Of the 95 individual diseased cattle, 19 were found positive for at least one viral antigen. It was found that especially BHV-1 and PI-3 virus are important causative agents in cattle respiratory disease, both or in combination with other pathogenic agents. Multiple infection in virologically positive herds was observed in six (9.8%) of 61 animals tested.
