Infectious colitis can present with frequent bloody, small volume stools, often associated with fever, abdominal cramps, tenesmus, and rectal urgency. Although the commonest infectious cause of bloody diarrhea in adults in the West is Campylobacter, pseudomembranous colitis, caused by Clostridium difficile, is one of the most common nosocomial infections; it is usually seen during or following antibiotic administration. Its clinical presentation ranges from mild diarrhea to severe colitis and hematochezia. Patients infected with Shiga toxin-producing Escherichia coli (particularly serotype O157:H7) present with acute onset of bloody diarrhea, especially without fever, and with the hemolytic-uremic syndrome. In immunocompromised hosts, most episodes of lower GI bleeding are associated with opportunistic infection, such as cytomegalovirus colitis.
