Sexually transmitted enteric and rectal infections in homosexual men.

Intestinal infections represent a major health problem in homosexual men. The spectrum of potential pathogens includes classic sexually transmitted pathogens, enteric bacterial and protozoan pathogens, and a wide range of opportunistic infections seen in patients with human immunodeficiency virus (HIV) infections. Diagnosis and treatment of these infections must be comprehensive, including a full microbiologic evaluation, assessment of the immuno-competence of the patient, and repeat examination following completion of therapy.
