A parasitological survey was carried out among Terena Indians living in the Tereré settlement in the municipality of Sidrolândia, State of Mato Grosso do Sul, Brazil. Single samples of feces from 313 Indians were processed by means of the spontaneous sedimentation method. In the population studied, 73.5% were infected with at least one intestinal parasite or commensal. Protozoa predominated. Blastocystis hominis (40.9%), Entamoeba coli (33.2%) and Entamoeba histolytica/Entamoeba dispar (31.6%) were the most common. Bivariate analysis showed that females were generally more infected and presented higher rates of infection by Entamoeba histolytica/Entamoeba dispar and Entamoeba coli. Males were more infected by hookworms and Strongyloides stercoralis than females. The precarious sanitary conditions of the Tereré settlement are probably a contributory factor towards the high prevalence of intestinal protozoa.
在巴西南马托格罗索州西德罗兰迪亚市特雷雷定居点生活的特雷纳印第安人中开展了一项寄生虫学调查。采用自然沉淀法对313名印第安人的粪便单样本进行了处理。在所研究的人群中，73.5%的人感染了至少一种肠道寄生虫或共生体。原生动物占主导地位。人芽囊原虫（40.9%）、结肠内阿米巴（33.2%）和溶组织内阿米巴/迪斯帕内阿米巴（31.6%）最为常见。双变量分析表明，女性总体感染率更高，溶组织内阿米巴/迪斯帕内阿米巴和结肠内阿米巴的感染率也更高。男性感染钩虫和粪类圆线虫的比例高于女性。特雷雷定居点不稳定的卫生条件可能是肠道原生动物高流行率的一个促成因素。
