 IS MYCOBACTERIUM AVIUM SUBSP.PARATUBERCULOSIS AN ETIOLOGICAL FACTOR IN CROHN'S DISEASE?
Paratuberculosis is a chronic inflammation of the intestine in animals caused by the slow growing and fastidious bacterium, Mycobacterium avium subsp.paratuberculosis (MAP).
Paratuberculosis is both a contagious and enzootic disease of ruminants caused by the multiplication of a specific bacterium, Mycobacterium avium subsp paratuberculosis (MAP) in the intestinal mucous membrane.
MAP was identified in 26 of 40 (65%) Crohn’s disease, in 1 of 23 (4.3%) ulcerative colitis, and in 5 of 40 (12.5%) control tissues (19).

 A causal role for Mycobacterium avium subspecies paratuberculosis in Crohn’s disease?
These issues include difficulties in culturing MAP in vitro, the lack of knowledge related to the environmental distribution of MAP, the relatively high prevalence of subclinical MAP infections in domestic animals and perhaps humans as well, and problems with antibody recognition to detect present or past MAP infection.
The presumed association between MAP and Crohn’s disease, or the ratio of Crohn’s disease in those with and without active MAP infection, has not been established, nor has the temporality of the association, or evidence that MAP infection precedes the development of Crohn’s disease, been established in human populations.
MAP infection may occur before or after the development of Crohn’s disease and in either case may have little influence on the natural history of the disease.

 Crohn's Disease Info Center
The microorganism, mycobacterium avium subspecies paratuberculosis, has been established in the veterinary literature to be the cause for Johne's disease, a disease causing colitis in cattle, sheep, and subhuman primate species.
An important milestone in the research of mycobacterium occurred in 1985, when a genetic code (the IS900 insertion sequence) that is unique for mycobacterium paratuberculosis was found in both the bacillary and spheroplast forms of this microorganism.
Since mycobacterium paratuberculosis is often resistant to conventional antibiotics, newer forms of treatment will need to be studied to pursue more effective treatments.

paratuberculosis (MAP), the cause of Johne's disease in cattle, sheep and goats, may have a role in Crohn's disease in humans.
An association between MAP and Crohn's disease is not proven, but neither can it be discounted on the basis of current evidence.
A precautionary approach is therefore warranted in relation to the existence of MAP in food, and action is needed to reduce the prevalence of Johne's disease in the cattle population worldwide, in order to minimize public exposure to this potential human pathogen.

Heat treatment is the most effective measure to reduce MAP during the manufacture of milk and milk products, and of meat and products derived from meat.
Issues that remain include the possibility of an association of MAP with the disease and, should there prove to be an association, the dose response relationship that would allow a proper risk assessment to be undertaken, targeting all possible sources of MAP.
