Abstract

The study examines the distribution of Trichuris trichiura infection in a village community in St Lucia, West Indies. The infection intensity of the same age-stratified population was assessed (by drug expelled worm burden and faecal egg count) at the initiation of the study, and after 17 months of reinfection following treatment. The frequency distribution of worm numbers per person was similar at both periods of sampling. There was a significant correlation between the initial infection intensity of an individual, and the intensity acquired by the same individual following the 17 month period of reinfection. This relationship was observed in a broad range of host age classes. The study provides firm evidence that individuals are predisposed to heavy (or light) T. trichiura infection.

摘要

该研究调查了西印度群岛圣卢西亚一个乡村社区中鞭虫感染的分布情况。在研究开始时以及治疗后17个月再次感染后,对同一年龄分层人群的感染强度进行了评估(通过驱虫后虫体负担和粪便虫卵计数)。两个采样时期每人蠕虫数量的频率分布相似。个体的初始感染强度与该个体在17个月再次感染期后的感染强度之间存在显著相关性。在广泛的宿主年龄组中都观察到了这种关系。该研究提供了确凿的证据,表明个体易患重度(或轻度)鞭虫感染。
