Parasitological examinations were carried out during July to December, 1989, on 485 inhabitants of four villages in São Lourenço da Mata, 25 km northwest of Recife, Pernambuco, Brazil. Approximately 99.6% of the inhabitants were infected with at least one species of intestinal parasites. A high prevalence of Schistosoma mansoni (82.1%), hookworm (80.2%) Trichuris trichiura (69.9%), Ascaris lumbricoides (61.9%) and Entamoeba coli (36.7%) infections were demonstrated. Test tube cultivation revealed that the most common species of hookworm in this region was Necator americanus (88.4%), and also that the prevalence of Strongyloides stercoralis was 5.8%. Three hundred and thirty-four sera were serologically examined for amoebiasis by the gel diffusion precipitation test (GDP) and enzyme-linked immunosorbent assay (ELISA). No positive reaction was observed in all sera as examined by GDP, while 24 sera were positive by ELISA.
1989年7月至12月期间，对位于巴西伯南布哥州累西腓西北25公里处圣洛伦索达马塔的四个村庄的485名居民进行了寄生虫学检查。大约99.6%的居民感染了至少一种肠道寄生虫。结果显示，曼氏血吸虫感染率很高（82.1%），钩虫感染率（80.2%）、鞭虫感染率（69.9%）、蛔虫感染率（61.9%）以及结肠内阿米巴感染率（36.7%）都很高。试管培养显示，该地区最常见的钩虫种类是美洲板口线虫（88.4%），粪类圆线虫的感染率为5.8%。采用凝胶扩散沉淀试验（GDP）和酶联免疫吸附测定（ELISA）对334份血清进行了阿米巴病血清学检测。经GDP检测，所有血清均未观察到阳性反应，而经ELISA检测，有24份血清呈阳性。
