摘要: 1987-1989年采用生理盐水涂片法和碘液染色法抽查了广西20个县、100个点共51883人肠道原虫感染者。共查见肠道原虫11种。各种原虫感染率分别为:溶组织内阿米巴1.5%、结肠内阿米巴3.2%、微小内蜒阿米巴1.2%、哈氏内阿米巴0.2%、布氏嗜碘阿米巴0.2%、脆弱双核阿米巴0.002%、贾第虫3.2%、结肠小袋纤毛虫0.04%、人毛滴虫0.2%、肠内滴虫0.01%和中华内滴虫0.01%。男、女人群原虫感染率分别为8.5%和9.1%。0-、5-、10-、15-、20-、30-、40-、50-、60-、70-和80岁以上各年龄组的原虫感染率依次为7.6%、10.6%、9.4%、9.3%、

Abstract: Fecal examination using direct smear and iodine staining was carried out in 51 883 subjects in twenty counties of Guangxi in 1987-1989. Altogether 771 subjects were found to harbor the cysts of Entamoeba histolytica , the average infection rate being 1.5%. The highest infection rate (2.0%) was at the age group of 30 to 39. A total of 1 641 subjects were found parasitized by the cysts of Giardia lamblia , the average infection rate being 3.2%. The infection rate was significantly higher in males (3.5%) than in females (2.9%) ( P 0.01). The highest infection rate (5.9%) was at the age group of 5-9. Entamoeba coli, Endolimax nana, Iodamoeba buetschlii,Entamoeba hartmanni, Trichomonas hominis and Balantidium coli were also detected in the survey. Water pollution is the essential cause of prevalence of protozoan infections; evidently, environmental sanitation should be stressed in control practice.
