To the Editor: In their article on intestinal infections in homosexual men (Sept. 8 issue)1 Quinn et al. make no mention of infestations with spirochetes other than Treponema pallidum. They do not describe the use of either anaerobic culture or routine histopathology in the detection of infection. Intestinal spirochetosis, caused by a newly described organism,2 may be associated with diarrhea or abdominal pain.3 Its exact role in the pathogenesis of colorectal disease remains unclear.4 It is found often enough in homosexual men (36 per cent of those seen at a genitourinary clinic in Glasgow) to merit further attention.
