Epi. 201 - Case-control Study to Identify Management Practices Associated with Morbidity or Mortality Due to Bovine Anaplasmosis in Mississippi Cow-calf Herds

AABP Executive Director Dr. Fred Gingrich is joined by Dr. Isaac Jumper, Assistant Professor at Mississippi State University College of Veterinary Medicine to discuss the paper “Case-control study to identify management practices associated with morbidity or mortality due to bovine anaplasmosis in Mississippi cow-calf herds” published in the Bovine Practitioner and available open-access in the online first edition. Jumper starts by discussing bovine anaplasmosis and the challenges associated with its control in cow-calf herds.  

The objective of this study was to determine if management practices, such as feeding chlortetracycline (CTC), are associated with illness or death from bovine anaplasmosis in Mississippi cow-calf herds. We discuss some of the epidemiologic terms used in the paper and the results of the study. This study found that providing CTC was associated with case herd status and Jumper provides some possible explanations for this finding. Veterinarians should routinely review protocols, especially antimicrobial protocols for treatment, prevention and control of disease, to optimize antimicrobial stewardship and animal health.
