MPTSA - KIT TAQVET MYCOBACTERIUM PARATUBERCULOSIS ADVANCED
Paratuberculosis (Johne's disease) is a chronic, contagious infection caused by Mycobacterium avium sub. paratuberculosis (which belongs to the same family as the causative agent of tuberculosis). This incurable disease affects bovines, caprines and other wild and domesticated ruminants. The symptoms—chronic inflammation of the intestine, mesenteric lymph node lesions, diarrhoea, weight loss and oedema—usually appear in animals of over two years of age with an advanced stage of the disease. Mycobacterium paratuberculosis is particularly hardy and is excreted in great numbers in the faeces of infected animals. Infection occurs early in life through the ingestion of feed, water or maternal milk contaminated with faecal material. The disease is highly complex and depends on many factors. How the disease will progress depends on the resistance of the bacillus, the rate of its excretion into the environment, latent phases and antibody responses (which are sometimes delayed). Control depends on identifying and removing infected animals: the main diagnostic tools are PCR and ELISA tests, and stool culture.
