[The pathogenesis of the bowel infection with the Mycobacterium tuberculosis].

The prevalence of primary intestinal tuberculosis is increasing with social change and medical progress. However, it remains unknown whether or not primary intestinal tuberculosis exists without the involvement of other internal organs. This review verifies hypotheses about infectious courses of intestinal tuberculosis. We also evaluate the significance of bowel infection. As a result, we found some patients with intestinal tuberculosis who do not have tuberculosis lesions in other internal or external organs, and the tubercle bacillus, which is ordinarily transmitted with airborne droplet nuclei, might cause oral transmission by several factors.
