What causes Johnes?

Johne’s disease is a contagious, chronic, and usually fatal infection that affects primarily the small intestine of ruminants. Johne’s disease is caused by Mycobacterium avium subspecies paratuberculosis (M. avium subsp. paratuberculosis), a hardy bacterium related to the agents of leprosy and TB.
