Crohn's disease is believed to be caused by a dysregulated immune response to gut bacteria, though the exact mechanism is unknown. This is evidenced by the disease's links to genes involved in bacteria defense and its occurrence in the ileum and colon, the most bacteria-dense segments of the intestine. [23]

Major groups of parasites include protozoans (organisms having only one cell) and parasitic worms (helminths). Of these, protozoans, including cryptosporidium, microsporidia, and isospora, are most common in HIV-infected persons. Each of these parasites can infect the digestive tract, and sometimes two or more can cause infection at the same time.

At some point after the first surgery, Crohn's disease can recur in the healthy parts of the intestine, usually at the resection site. [76] (For ...
