Johne’s disease is a chronic, debilitating enteritis of ruminants caused by infection with Mycobacterium paratuberculosis (MAP). During the active stage of the infection and prior to onset of clinical disease, animals generally develop antibodies to M. paratuberculosis antigens. Uninfected animals lack specific antibodies to M. paratuberculosis. Our ELISA test PARACHEK 2 detects antibodies to M. paratuberculosis in serum, plasma, and milk in cattle. PARACHEK 2 is highly specific (>99%), and sensitivity is approximately 41%. A positive result indicates the animal is likely to be infected with M. paratuberculosis and that there are potentially other infected animals in the herd.
