An epidemiologic study was conducted in San Cayetano, a village in the province of Corrientes, Argentina, to determine the prevalence of intestinal parasitoses in children. Eighty-eight households were randomly selected. Stool samples were collected from 207 children (72% of the school-age population and 12% of the total village population) over a period of six consecutive days, and were subjected to microscopic examination. Of the samples examined, 170 (83%) contained one or more parasites, of which the most frequently found was Blastocystis hominis (in 43% of the samples). Other parasites and commensals detected included Giardia lamblia (29%), hookworms (27%), Entamoeba coli (27%), Enterobius vermicularis (4%), Strongyloides stercoralis (2%), and Ascaris lumbricoides, Trichuris trichiura, Taenia saginata, Isospora belli, Iodamoeba bütschlii, and Balantidium coli (each 0.5%). The high observed prevalence of intestinal parasitoses indicates active parasite transmission in San Cayetano as a result of poor environmental hygiene-ascribable largely to a lack of public water supply, sewerage, and waste removal services.
在阿根廷科连特斯省的一个村庄圣卡耶塔诺开展了一项流行病学研究，以确定儿童肠道寄生虫病的患病率。随机选取了88户家庭。在连续六天的时间里，从207名儿童（占学龄人口的72%，占全村总人口的12%）采集粪便样本，并进行显微镜检查。在检查的样本中，170份（83%）含有一种或多种寄生虫，其中最常见的是蓝氏贾第鞭毛虫（占样本的43%）。检测到的其他寄生虫和共生体包括十二指肠贾第虫（29%）、钩虫（27%）、结肠内阿米巴（27%）、蠕形住肠线虫（4%）、粪类圆线虫（2%）以及蛔虫、鞭虫、牛带绦虫、贝氏等孢球虫、布氏嗜碘阿米巴和结肠小袋纤毛虫（各占0.5%）。观察到的肠道寄生虫病高患病率表明，由于环境卫生差，圣卡耶塔诺存在活跃的寄生虫传播，这主要归因于缺乏公共供水、污水处理和垃圾清除服务。
