The prevalences of intestinal parasites among the residents of three South American Indian villages in the process of acculturation were compared with those found in earlier unpublished surveys in two newly contracted village.s Although one individual in an acculturating village harbored 11 different intestinal parasites, in general the average number of different parasitic species carried per person was somewhat higher in the newly contacted villages. Helminth egg counts, performed on direct smears of each specimen from one newly contacted village, were low. There were no sex-associated differences in prevalences. The overall prevalences, unadjusted for age, were among the highest recorded for Amerindians. No Taenia species were present. Balantidium coli was present in two acculturating villages, concomitant with the beginning of agricultural practices which include raising swine. No cases of moderate or severe protein-calorie malnutrition was observed in any of the villages during the surveys. These limited data provide a baseline for future comparisons and, perhaps, a glimpse into the past.
对三个处于文化适应过程中的南美印第安村庄居民体内肠道寄生虫的流行情况，与两个新接触村庄早期未发表的调查结果进行了比较。尽管一个处于文化适应过程中的村庄里有一人感染了11种不同的肠道寄生虫，但总体而言，新接触村庄中每人携带的不同寄生虫种类平均数量略高。对一个新接触村庄的每个样本直接涂片进行的蠕虫卵计数很低。在流行率方面不存在与性别相关的差异。未经年龄调整的总体流行率在美洲印第安人有记录的情况中处于最高水平。未发现绦虫种类。结肠小袋纤毛虫出现在两个处于文化适应过程中的村庄，这与包括养猪在内的农业实践的开始相伴。在调查期间，任何村庄均未观察到中度或重度蛋白质 - 热量营养不良病例。这些有限的数据为未来的比较提供了基线，或许也让我们得以窥见过去。
