title: Amoebiasis in homosexual men.
abstract: The clinical, histopathological, and serological features of 35 homosexual men with infection with Entamoeba histolytica were studied and compared with a group of 35 non-infected homosexual men. Each isolate was of Zymodeme type I. Although there was no significant difference in the numbers of infected and non-infected men with gastrointestinal symptoms (48.6% and 28.6% respectively), the mean duration of symptoms was greater in with amoebiasis (p less than 0.05). The histology of the rectal mucosa was abnormal in 17 (63.0%) of the 27 men with amoebic infection only and in two (7.4%) of the 27 control subjects (p less than 0.001). Serum antibodies reactive with E. histolytica were not shown in any patient.
