Researchers have discovered that Mycobacterium avium paratuberculosis (MAP) bacteria live in 92% of Crohn's disease patients. The bacteria, which is found in pasteurized cows' milk in the United Kingdom and other places, may play a role in the development of both Crohn's disease and IBS. This is not a new theory, the first strains of the bacteria were found in Crohn's patients in 1984, but researchers were surprised by the additional link to IBS.


My son has Crohn’s Disease. When he was diagnosed, we learned that he is part of a cluster of people with the disease in our community. Since this seemed odd, we began to look into environmental connections. We discovered research involving MAP and directed our research in that direction. Some of the kids in the cluster were tested for MAP and all came back positive. My son decided to check local water sources for MAP as part of a science research project for school. His mentor for the project is a microbiology professor from Virginia Tech. The research is ongoing, put all signs point to the existance of MAP in the local water samples collected.
My 19 yr old son also has Crohn’s (diagnosed 6/06 and needed surgery 10/06). We live in GA and also see a cluster. There is a vaccine being researched by John Hermon Taylor in the UK to cure and prevent Crohn’s based on MAP). Why is there so little info in US?
my daugter(32)already 10 years Crohn’s diagnosted.As a Microbiologist I watch all the workers regarding MAP.But the mainstream of the medical community is excommunicating them.
There is much information about the connection Crohn’s-MAP in the net and as it seens to me the linkage is obvious
but medicine world is looking after the coin under the lamp.It is economically.
