Johne's disease (paratuberculosis) is a chronic, granulomatous infection of the intestinal tract of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). There is no approved treatment, no known way to eliminate the infection once established, nor is there an effective vaccine for the disease. Johne's disease (JD) has emerged as an

Summary The pathology of Johne's disease in the sheep as it occurs in Scotland is given. On histological appearances it has been divided into four groups. Group 1 is characterised by masses of epithelioid cells. The pigmented variety of M. Johnei is most commonly present in very large numbers.
