In 109 patients with chronic diarrhea colonic biopsies were examined for the presence of specific microorganisms. A positive result was obtained in 48% of patients with ulcerative colitis, 50% with Crohn's disease, 21% with non-specific colitis and 36% with non-specific proctitis. Chlamydiae were found most frequently in all groups. Obligate enteropathogenic bacteria were isolated in only three cases of nonspecific colitis. Of the facultatively enteropathogenic organisms Klebsiella and Pseudomonas aeruginosa were isolated in 31% and 24%, respectively, of patients with ulcerative colitis, in 21% and 7% of patients with Crohn's disease, and in 10% and 6% of patients with non-specific colitis. Whereas chlamydial proctitis is a well-known disease, the results of this study point also to a possible pathogenic role of chlamydiae in the proximal colon. Facultatively enteropathogenic organisms causing acute diarrhea might have aetiologic relevance in some cases of chronic non-specific colitis.

We studied 388 homosexual or bisexual men from the Baltimore-Washington area to define the spectrum of enteric pathogen carriage in a population at high risk for "gay bowel syndrome" in association with human immunodeficiency virus infection. Seventy-seven patients with acquired immunodeficiency syndrome, 68 gay men with symptoms of acute diarrhea or proctitis, and 243 gay men without gastrointestinal symptoms and participating in a natural history study of human immunodeficiency virus infection were selected for study. Approximately 12% of the asymptomatic men harbored at least one enteric pathogen; the most frequently recovered were Chlamydia trachomatis, herpes simplex virus, and Giardia lamblia. Men carrying a pathogen were more likely to be human immunodeficiency virus seropositive (48%) than men without a pathogen (25%) (p = 0.018), more likely to have fewer T helper cells (p = 0.015), and more likely to have a mucopurulent exudate (p = 0.014). We recovered an agent of enteric disease from 68% of gay men presenting with diarrhea or proctitis. Campylobacter species, herpes simplex virus, Neisseria gonorrhoeae, C. trachomatis, G. lamblia, and Shigella species were identified most frequently. The most common pathogen associated with diarrhea in acquired immunodeficiency syndrome was Cryptosporidium (16% of 49 cases). Other agents identified were Clostridium difficile, Vibrio parahemolyticus, Campylobacter species, G. lamblia, Isospora, and cytomegalovirus. Approximately half of the identifiable etiologic agents of diarrhea in acquired immunodeficiency syndrome patients were treatable with antibiotics, but these agents required special culture procedures for detection.
