Paratuberculosis (Johne's disease) and the biology of its causative agent, Mycobacterium paratuberculosis. Johne's disease is a prevalent, costly infectious disease affecting dairy cattle and other ruminants. Improving methods of detecting the disease is the primary focus of the laboratory. In collaboration with other investigators, the diagnostic techniques available in our laboratory are used to study the epidemiology, economic impact, zoonotic potential, and pathogenesis of the disease in a variety of species (cattle, goats, llamas, etc.). This has led to an increased volume of clinical submissions to the laboratory.  Annually our lab tests roughly 15,000  serum and 8,000 fecal samples for diagnosis and control of Johne's disease. Another focus of the laboratory is investigation of the relationship between Chrohn's disease, a chronic inflammatory bowel disease in humans, and M. paratuberculosis. In addition to diagnostic services, the laboratory provides information and education through telephone consultation, herd visits, veterinary and producer presentations, lay publications and through the Johne's Information Center website.
