A study was undertaken to determine the prevalence of intestinal parasites in a group of rural, economically disadvantaged children. Thirty-four percent of 108 children were found to have a clinically significant parasite. The most common organism was Giardia lamblia (22 percent). Those children with Giardia were significantly (P = .05) smaller than those with negative stool examinations. Even in areas with a low overall prevalence of intestinal parasites, certain high-risk groups may have significant levels of infection.
一项研究旨在确定一组农村经济贫困儿童肠道寄生虫的感染率。在108名儿童中，34%被发现患有具有临床意义的寄生虫。最常见的病原体是蓝氏贾第鞭毛虫（22%）。感染蓝氏贾第鞭毛虫的儿童明显（P = 0.05）比粪便检查呈阴性的儿童体型更小。即使在肠道寄生虫总体感染率较低的地区，某些高危人群也可能有较高的感染水平。
