During 1 year, the association between microbiological and pathological findings in 72 lungs from calves submitted to the Danish Veterinary Laboratory for diagnostic purposes was studied. All cases mere evaluated pathologically and bacteriologically, whereas only 68 cases were examined for the presence of bovine respiratory syncytial virus (BRSV), parainfluenza-3 virus (PI-3 virus) and bovine coronavirus, 62 cases for bovine viral diarrhoea virus (BVD), 45 cases for bovine adenovirus and 51 cases for mycoplasmas.
Based on histopathological examination, the cases were diagnosed as fibrinous and/or necrotizing bronchopneumonia, suppurative bronchopneumonia, embolic pneumonia and others. The diagnoses were based on the dominating and most severe lesions in each lung. Haemophilus somnus, Pasteurella multocida, Actinomyces pyogenes, P. haemolytica and BRSV were the most commonly found bacterial and viral lung pathogens, respectively.
Pasteurella spp. and H. somnus were often associated with the more severe fibrino-necrotizing type of bronchopneumonia, whereas BRSV was primarily detected in cases of suppurative bronchopneumonia, Mycoplasma bovis was isolated from one case only, whereas M dispar, M bovirhinis and Ureaplasma diversum were present, often concomitantly in the majority of cases.
Aspergillus fumigatus was isolated from one case.
