摘要: Our objective was to determine the prevalence of intestinal protozoa in homosexual men attending a sexually transmitted diseases (STD) clinic, compare it with previous study from same and examine relationship, if any, between presence sexual practices. Men who consecutively attended clinic gave history having had recent contact another male were invited provide stool sample for protozoological examination. Diarrhoeal samples examined by direct microscopy trophozoites cysts and, after staining, Cryptosporidium spp. In all cases, modified formol-ether method used concentrate protozoal before microscopy. One hundred seventy-five 257 participate provided sample. At least one species protozoan found 99 (57%) men. Giardia intestinalis identified only 5 (3%) Blastocystis hominis 46 (26%) men, but this not associated diarrhoea. Other than Entamoeba dispar/histolytica G. intestinalis, which remained unchanged, proportion harboured non-pathogenic significantly increased 1981/82. A correlation oral-anal sex or peno-insertive peno-receptive anal intercourse found. There also no number carried these The foreign travel man recently travelled outside UK. showed that, although infection is low, giardiasis still transmissible amongst individual practices
