To determine the prevalence of intestinal protozoal and helminthic infection in a rural population.
Seventy-eight members of 15 families from a village were studied. Stool samples from all subjects were examined on alternate days for one month.
The overall prevalence rate of various parasitic infections was 97.4%, with only 2 of 78 subjects not excreting parasites in any of their 15 samples. Eighteen (23.1%) persons had only one type of parasite, while 58 (74.3%) excreted multiple parasites. Giardia and Cryptosporidium were the commonest protozoan infections, affecting 42/78 (53.8%) and 31/78 (39.7%), respectively. Hookworm infestations were the commonest helminthic infections, seen in 48/78 (61.5%). Based on excretion patterns, the asymptomatic individuals could be divided into 2 groups of infrequent and frequent excretors, indicating that the host response may determine the level of parasite replication in the gut.
确定农村人群肠道原生动物和蠕虫感染的患病率。
对来自一个村庄的15个家庭的78名成员进行了研究。在一个月的时间里，每隔一天对所有受试者的粪便样本进行检查。
各种寄生虫感染的总体患病率为97.4%，78名受试者中只有2人在其15份样本中均未排出寄生虫。18人（23.1%）仅感染一种寄生虫，而58人（74.3%）排出多种寄生虫。贾第虫和隐孢子虫是最常见的原生动物感染，分别影响42/78（53.8%）和31/78（39.7%）的人。钩虫感染是最常见的蠕虫感染，见于48/78（61.5%）的人。根据排泄模式，无症状个体可分为排泄不频繁和频繁的两组，这表明宿主反应可能决定肠道内寄生虫的复制水平。
