Fresh stool samples obtained from 1407 adult patients who sought treatment in Takeo province hospital and 332 Takeo preschool and school-age children from 3 to 18 years of age were examined for the presence of intestinal parasites using the technique of native preparation and the flotation method of Faust with subsequent staining with Lugol solution to demonstrate cysts. In hospital patients, a total of 13 protozoan and 9 helminth species were diagnosed. The prevalence of Entamoeba histolytica (cysts and trophozoites) was highest in the age group 15-18 years (18.3%), the peak prevalence of Gairdia lamblia (27.6%) occurred in children of the age group 6-9 years. The highest frequency distribution of Pentatrichomonas hominis (20.1%) was recorded in 3 to 5 years old, that of Enteromonas hominis (12.8%) in 6 to 9 years old. The predominant helminth was Ancylostoma duodenale, with the peak prevalence (65.2%) in patients older than 18 years, followed by Ascaris lumbricoides and Strongyloides stercoralis. Almost half of children patients under 6 was infected with at least two species of parasites, patients over 6 were infected simultaneously with two or more intestinal parasites in an absolute majority of cases. In Takeo preschool and school children the spectrum of diagnosed protozoan and helminth species was somewhat narrower than seen in hospital patients, but their prevalence rates were higher, except for the flagellate Pentatrichomonas hominis. The highest prevalence rates recorded were for E. histolytica 29.5% (age category 10-14 years), for G. lamblia 34.8% (age category 6-9 years), for P. hominis 19.3% (age category 3-5 years), for E. hominis 10.5% (age category 3-5 years), for A. duodenale 85.9% (age category 15-18 years), for A. lumbricoides 26.1% (age category 6-9 years), and for S. stercoralis 18.8% (age category 6-9 years). As many as 70% of children at the age between 6 and 15 years were simultaneously infected with two or three species of intestinal parasites.
对从茶胶省医院就诊的1407名成年患者以及332名3至18岁的茶胶学龄前和学龄儿童采集的新鲜粪便样本，采用生理盐水涂片法和福氏漂浮法进行检查，以检测肠道寄生虫的存在，随后用卢戈氏溶液染色以显示包囊。在医院患者中，共诊断出13种原生动物和9种蠕虫。溶组织内阿米巴（包囊和滋养体）的感染率在15 - 18岁年龄组中最高（18.3%），蓝氏贾第鞭毛虫的感染率峰值（27.6%）出现在6 - 9岁年龄组的儿童中。人五毛滴虫的最高频率分布（20.1%）记录在3至5岁儿童中，人肠滴虫的最高频率分布（12.8%）记录在6至9岁儿童中。主要的蠕虫是十二指肠钩口线虫，18岁以上患者的感染率峰值为65.2%，其次是蛔虫和粪类圆线虫。6岁以下儿童患者中几乎一半感染了至少两种寄生虫，6岁以上患者在绝大多数情况下同时感染了两种或更多种肠道寄生虫。在茶胶学龄前和学龄儿童中，诊断出的原生动物和蠕虫种类范围比医院患者略窄，但除了鞭毛虫人五毛滴虫外，他们的感染率更高。记录到的最高感染率分别为：溶组织内阿米巴29.5%（10 - 14岁年龄组）、蓝氏贾第鞭毛虫34.8%（6 - 9岁年龄组）、人五毛滴虫19.3%（3 - 5岁年龄组）、人肠滴虫10.5%（3 - 5岁年龄组）、十二指肠钩口线虫85.9%（15 - 18岁年龄组）、蛔虫26.1%（6 - 9岁年龄组）、粪类圆线虫18.8%（6 - 9岁年龄组）。6至15岁的儿童中有多达70%同时感染了两种或三种肠道寄生虫。
