Surveys were conducted in the southern Malay peninsula to assess intestinal parasitism in the aboriginal ethnic minority groups. Faecal specimens from 1 273 persons were examined by the thiomersal-iodine-formol direct-smear technique. Prevalences are reported and, for helminth infections, data on worm burdens. The state of sanitation in each of 9 cultural-ecological groups was assessed by means of a simplified system of scoring for variables. Particular attention was paid to relationships between cultural and ecological factors, sanitation, and observed patterns of intestinal parasitism. The author also discusses the fact that the number of parasitic species diminishes in habitats simplified by man, whereas an increase occurs in the prevalence and intensity of the more adaptable species that persist in ecosystems of low complexity.
在马来半岛南部开展了调查，以评估原住民少数民族群体中的肠道寄生虫感染情况。采用硫柳汞-碘-甲醛直接涂片技术对1273人的粪便样本进行了检查。报告了感染率，对于蠕虫感染，还报告了蠕虫负荷数据。通过一个简化的变量评分系统对9个文化生态群体各自的卫生状况进行了评估。特别关注了文化和生态因素、卫生状况与观察到的肠道寄生虫感染模式之间的关系。作者还讨论了这样一个事实，即在人类简化的栖息地中，寄生虫种类数量减少，而在低复杂性生态系统中持续存在的适应性更强的物种的感染率和感染强度则会增加。
