JF The British Journal of Venereal Diseases JO Br J Vener Dis FD BMJ Publishing Group Ltd SP 193 OP 195 DO 10.1136/sti.60.3.193 VO 60 IS 3 A1 Chin, A T A1 Gerken, A YR 1984 UL http://sti.bmj.com/content/60/3/193.abstract AB A total of 83 male homosexuals were studied to ascertain the carriage of intestinal protozoal cysts. The homosexual group had a significantly (p less than 0.0005) higher prevalence than a control group. One or more types of protozoa were found in 33 homosexuals. The carriage of intestinal protozoal cysts was associated with particular sexual practices and promiscuity, but not with symptomatic bowel disorders. The possible implications of the carriage of these cysts are discussed.
