We determined the prevalence of intestinal parasite infections between 1993 and 1998 in the populations of a poor quarter of Recife (Pernambuco), in two townships in the sugar cane belt and in three villages of the semi-arid area far from the coast. Intestinal schistosomiasis was present in the sugar-growing area but was not observed in the populations inland that use dams to provide irrigation and fishing. Ascaris was very common in the city and the sugar cane belt and large numbers of hookworms were observed, especially in the sugar-growing area. These nematodes were very rare in the semi-arid area. This distribution probably results from both climatic conditions and human behavior. The high frequency of Amoeba cysts demonstrates that the peasants, farmers and fisherman living in these areas have poor hygiene practices. There are probably many, complex relationships between education, income, lifestyle and intestinal parasite infections.
我们确定了1993年至1998年间累西腓（伯南布哥州）一个贫困街区、甘蔗种植带的两个城镇以及远离海岸的半干旱地区三个村庄人群中肠道寄生虫感染的流行情况。甘蔗种植区存在肠道血吸虫病，但在内陆使用水坝进行灌溉和捕鱼的人群中未观察到。蛔虫在城市和甘蔗种植带非常常见，并且观察到大量钩虫，尤其是在甘蔗种植区。这些线虫在半干旱地区非常罕见。这种分布可能是气候条件和人类行为共同导致的。阿米巴囊肿的高频率表明生活在这些地区的农民、农场主和渔民卫生习惯较差。教育、收入、生活方式与肠道寄生虫感染之间可能存在许多复杂的关系。
