In animal studies, a local irritant (eg, acetic acid, trinitrobenzene sulfonic acid) can be inserted via an enema into the colon of rats or rabbits to induce a chemical colitis. An interleukin-10 (IL-10) knockout mouse has been genetically engineered to have some characteristics similar to those of a human with IBD. The cotton-top marmoset, a South American primate, develops colitis very similar to ulcerative colitis when the animal is subjected to stress.
