Bacterial Waterborne Pathogens - Current and Emerging Organisms of Concern2006

6.2.1 Description The Mycobacterium avium complex (Mac) consists of 28 serovars of two distinct species: Mycobacterium avium and Mycobacterium intracellulare. Based on phenotypic and genetic characteristics, three subspecies of M. avium, including M. avium subsp. avium, M. avium subsp. paratuberculosis, and M. avium subsp. silvaticum, have been identified (Nichols et al., 2004). . Mac organisms, along with many other environmental mycobacteria species, comprise the non-tuberculous mycobacterium (NTM) group. These organisms are designated as NTM to distinguish them from Mycobacterium tuberculosis and Mycobacterium leprae, the infectious agents of tuberculosis and leprosy. Unlike their NTM counterparts, neither of the latter organisms is present in the environment, and, consequently, they are not a concern in drinking water.

World Health Organization: Pathogenic Mycobacteria in Water
Mycobacteria are a large group of microorganisms that inhabit a diverse range of natural environments: some species are capable of infecting humans and animals. Apart from the highly significant mycobacterial pathogens, we may presume that the majority of people in the water industry, until recently, would not be familiar with environmental mycobacteria. Nevertheless, environmental mycobacteria are a frequent cause of infection, and there is a growing body of evidence to show that water is a significant vehicle for the transmission of these organisms.

Canadian Food Inspection Agency: Annually Notifiable Diseases Annually notifiable diseases are diseases for which Canada must submit an annual report to the World Organisation for Animal Health (OIE) indicating their presence within Canada. In general, they are diseases that are present in Canada, but are not classified as reportable or immediately notifiable.

Johne's and Humans? In recent years there has also been speculation that M. avium subsp. paratuberculosis may also be implicated in Crohn's disease in humans. This is a disease characterized by ulceration of the intestine causing extreme pain and debilitation. While it may be an autoimmune disease, special tests that detect DNA (Polymerase Chain Reaction tests) have detected evidence of the organism in some Crohn's patients. M. avium subsp. paratubeculosis has also been cultured from a proportion of human cases. However, research to date has not confirmed a causal association between the two diseases. In addition, Crohn's disease has been reported in parts of the world that do not have Johne's disease. The jury is still out on this one

MAP-Canada does not advocate a particular cause of Crohn's disease.  Our website is intended only to present evidence.  Our readers may draw their own conclusions.  We are not medical specialists and do not offer any treatment or nutritional advice.  Our mission is not to lay blame on any individual or industry, but rather to urge the Government of Canada to address the evidence presented on this site.

Mise au Point:
MAP-Canada ne recommande aucune théorie particulière sur la cause de la maladie de Crohn.L'intente de notre site Web est simplement de présenter certaineévidence mais vous pouvez arriver à vos propres conclusions.Nous ne pouvons donner de conseils de nature médicale ou alimentaire. Notre mission ne consiste aucunement à blâmer un individuou une industrie mais
plutôt à s'assurer que le Gouvernement du Canada aborde l'évidence que nous présenton
