Bacteria identified from deep nasopharyngeal swabs and non-endoscopic bronchoalveolar lavage in calves on farms with a history of bronchopneumonia

Common BRD-associated bacteria occur on beef operations in Austria even in calves with mild BRD signs. Additionally, BAL and DNS are suitable for bacterial isolation from the respiratory tract and can provide an overview of the BRD-associated bacteria involved on the farm. We detected a poor agreement between the results of bacterial isolation from DNS and BAL samples in this study, except for M. bovis.
