To determine the occurrence and epidemiological aspects of intestinal parasites among the Parakanã indigenous people in the Paranatinga settlement (in the eastern Amazon Region), parasitological tests were performed in April 1992 and February 1995. One fresh stool specimen was obtained and immediately processed using the Hoffman and direct methods. Some 126 samples were obtained in April 1992 (from a total population of 215 individuals). Some 80. 2% (101) of those tested were infected with at least one species of intestinal parasite. Hookworms were found in 33.3%, Ascaris lumbricoides 42.8%, Trichuris trichiura 0.8%, and Strongyloides stercoralis 5.6%. Entamoeba histolytica and Giardia lamblia protozoans were found in 65.0% and 46.8% of those tested, respectively. A second parasitological survey was performed on 174 individuals (from a population of 253) in February 1995. 88.5% were infected. Note that prevalence in February 1995 was higher than in April 1992 (p=0.04). It was lower for hookworms, E. histolytica, and G. lamblia, with no S. stercoralis (p<0.05). Despite provision of health care in the Paranatinga community, prevalence of intestinal parasites is still extremely high, suggesting that primary and secondary health care should be increased immediately to increase the efficacy of prevention of intestinal parasites.
为了确定帕拉纳廷加定居点（位于亚马逊地区东部）的帕拉卡纳印第安人中肠道寄生虫的发生情况和流行病学特征，于1992年4月和1995年2月进行了寄生虫学检测。采集了一份新鲜粪便标本，并立即采用霍夫曼法和直接法进行处理。1992年4月采集了约126份样本（来自215人的总人口）。受检者中约80.2%（101人）感染了至少一种肠道寄生虫。钩虫感染率为33.3%，蛔虫感染率为42.8%，鞭虫感染率为0.8%，粪类圆线虫感染率为5.6%。溶组织内阿米巴和蓝氏贾第鞭毛虫原虫的感染率分别为受检者的65.0%和46.8%。1995年2月对174人（来自253人的总人口）进行了第二次寄生虫学调查。感染率为88.5%。请注意，1995年2月的患病率高于1992年4月（p=0.04）。钩虫、溶组织内阿米巴和蓝氏贾第鞭毛虫的患病率较低，且未发现粪类圆线虫感染（p<0.05）。尽管帕拉纳廷加社区提供了医疗保健，但肠道寄生虫的患病率仍然极高，这表明应立即加强初级和二级医疗保健，以提高预防肠道寄生虫的效果。
