Laboratory tests for bovine respiratory bacteria and antimicrobial resistance in commercial feedlot cattle: comparing culture, long-read metagenomics, and recombinase polymerase amplification
Cheryl L. Waldner
IntroductionThe risk to humans and animals from antimicrobial resistance (AMR) has increased the emphasis on antimicrobial stewardship in food animal agriculture. Current stewardship recommendations include increasing diagnostic laboratory testing to inform antimicrobial use for bovine respiratory disease (BRD) management in beef feedlot production, yet the performance of newer molecular and sequencing-based diagnostic tests in commercial settings remains poorly characterized.MethodsUsing nasoph
