==Description==
==Introduction==
Johne's Disease is a contagious and chronic disease of ruminants caused by the bacterium ''Mycobacterium avium subsp. paratuberculosis''. Affected species include cattle, sheep, goats and camelids. The disease is present worldwide with the highest prevalence occurring in dairy cattle. In these animals the disease is responsible for severe economic losses due to reduced reproductive performance, increased susceptibility to disease, reduced milk production and culling losses. Subclinical carriers can occur, shedding organisms in their faeces.
