Presentation Description / Summary: Bovine respiratory disease (BRD) is the most common and costly disease of beef and dairy cattle in North America. While multiple factors play a role in the development of BRD, infection of the lower respiratory tract with viruses and bacteria is ultimately responsible for the clinical signs seen in affected cattle. As a result, monitoring and testing for pathogens associated with BRD might facilitate the development of medically appropriate preventive health and treatment programs. In addition, practitioners have been encountering issues with antimicrobial resistance (AMR) in bacterial pathogens and, based on recently published data, the isolation of strains of Mannheima haemolytica, Pasteurella multocida, and Histophilus somni that are resistant to multiple antimicrobials is becoming a more frequent occurrence. Thus, monitoring for AMR in common bacterial pathogens might help with the design of effective therapeutic regimens. The purpose of these proceedings is to review the basic characteristics of antemortem diagnostic tests available for BRD and provide recommendations for their use in field settings
Learner Outcomes: Review the characteristics of diagnostics tests (Sensitivity, specificity, positive and negative predictive value, and likelihood ratio) Provide an understanding of the advantages and disadvantages of the different antemortem diagnostic tests available for use by practitioners when considering their use in beef or dairy cattle with BRD Provide recommendations for the use of the various diagnostic tests in different cattle populations when encountering issues with BRD
Learning Objectives:
Understand the characteristics of diagnostics tests relevant to BRD
Review diagnostics tests commonly used in the diagnosis and management of BRD and their clinical utility
Make decision as to which tests are most appropriate given a specific clinical scenario
