I tested positive for TB about 9 years ago via skin test. I don't know how I could've been exposed since I've never been outside of North America even. Anyways, I developed Crohn's 3 years later. I was wondering if it's possible it could actually be caused by MAP instead of TB since they're loosely related?

If a cow reacts positive to the basic TB test we humans often get, it has another chance.

The next step is to give it a Comparitive Cervical Tuberculin Test. This enables the vet to decide if the cow has real or Avian TB.

If the cow has proper TB it is usually culled. If the reaction is caused by Avian TB it is put back into the herd.

Cows that have MAP infection can test positive for bird TB. I have asked Government advisors in the uk why these cows cannot be removed from food production. They say its not financially viable.

If someone wants to do some good research, why not test people with a CCTT test, and you would have an answer?

There is still some TB in North America. So you would not have to have travelled outside of the continent to get it.

Look up intestinal tuberculosis, its difficult to distinguish the two.

Maybe you don't have Crohn's, maybe its TB.

Although MAP might give a positive on a TB test, who knows.
I know MAP lives in the lymphatic system, not the blood, so I'm not sure how that would work with the test.

In reading the link on the usefulness of biopsy versus PCR for distinguishing between Int. TB and Crohn's, it is too much to handle.

Really, too much. 64.1% detection rate, but TB is still accepted as the cause. However, when such statistics or even stronger statistics are presented in the case of MAP and Crohn's, they somehow seem to be neglected.

Not only that, one mycobacterium causes extremely similar pathological and endoscopic appearances to Crohn's, but to suggest that maybe another mycobacterium causes Crohn's would seem ridiculous, eh?

Yeah it would be ridiculous i guess because some GIs say that we only see granulomas in a proportion of Crohn's patients so it can't be caused by the one bacteria, but wait, we don't always see granulomas in Johne's or Intestinal TB do we...?
