The purpose of this project is to survey for Johne's Disease (Mycobacterium avium paratuburculosis) in caribou herds in Canada and one in Greenland.

In partnership with CARMA and northern wildlife agencies we are examining fecal samples for the presence of Mycobacterium avium paratubuculosis in order to determine the spatial distribution of Johne's disease in caribou and compare among herds. Fecal samples are cultured for M. paratuberculosis and polymerase chain reaction is used to detect genetic material from the Johne's organism if present. Where possible serum samples are also being tested for antibodies to M. paratuberculosis. Comparisons will be made between different herds.

Based on results in 2008, we decided to collect additional samples in 2009 to improve test sensitivity. These included ileum and ileo-caecal lymph nodes from caribou of the George River, Leaf River, Kangerlussuaq-Sisimiut, and Bathurst herds. Lab analyses of these samples is scheduled for 2010.
