Colitis caused by cytomegalovirus (CMV) infection is a rare form that typically is found in immunocompromised patients (eg, organ recipients who are receiving immunosuppressive treatment). It results in deep round ulcerations that have a tendency to bleed easily and profusely. Adenovirus infection can also cause a severe colitis in immunocompromised patients, especially those with AIDS, although patients with solid organ and bone marrow transplants are also at risk.
