Bovine respiratory disease (BRD) is one of the primary diseases affecting pre-weaned dairy calves and involves respiratory pathogens, such as Mannheimia haemolytica (Mh) and Pasteurella multocida (Pm). While agreement between methods for detection of bacterial pathogens in dairy calves with BRD is very good, there are limited data regarding how antimicrobial susceptibility (AS) of isolates collected via these methods agree. The objective was to evaluate agreement among the AS profiles of Mh or Pm obtained by transtracheal wash (TTW), nasal swab (NS), nasopharyngeal swab (DNP), and bronchoalveolar lavage (BAL) in pre-weaned dairy calves with BRD that were positive in all 4 samples.
