The expanding paratuberculosis epidemic and its implications for food. Michael T. Collins, DVM, PhD This presentation describes the extensive knowledge generated about Johne’s disease and extensive efforts in the U.S. to create strong control programs. It goes on to speculate why the epidemic appears to be continuing to expand and what consequences that may have for food safety and human health.

Epidemiology of paratuberculosis in dairy cattle Michael T. Collins DVM, PhD This 10 minute 15 slide mini-lecture describes the rate of M. paratuberculosis infection in dairy herds of several countries and how the infection spreads among herds and within herds. It also touches briefly on what happens to the animal once it becomes infected, the so called pathogenesis of Johne's disease.

Consensus recommendations on diagnostic testing of cattle for Johne’s disease in the U.S. Michael T. Collins, DVM, PhD This presentation describes Johne’s disease testing recommendations for both dairy and beef cattle in eight different situations.
