This study of feces sought to determine the prevalence of human intestinal parasites in the Kiliba area of the eastern DR Congo. Feces of 602 school children aged from 9 to 20 years were collected from April to June 2014 and examined. Direct analyses were supplemented with the Kato and Ritchie methods. The global prevalence of intestinal parasitosis in school-aged children in the Kiliba area was 91.4 % [95 % CI: 87.6-94.3%]. The frequency of helminthiasis was high at 73.8 % (95 % CI: 68.4-78.6%) and that of protozoa reached 32.9 % (95 % CI: 27.7-38.6%). Girls were infected more often than boys. The group aged 17-20 years had the highest infection rate (97.7 %), but no statistically significant difference was observed among the age groups studied. The most frequent parasite species were: Schistosoma mansoni (30.6 %), Strongyloides stercolaris (21.3 %), Entamoeba histolytica (17.6 %), Trichomonas intestinalis (14.6 %), Ankylostoma duodenale (13.6 %), Ascaris lumbricoides (12.6 %), Trichuris trichiura (9.0 %), Taenia saginata (6.6 %), and Giardia intestinalis (5.0 %). This investigation demonstrated the extreme frequency of these fecal infections. Preventive measures, including water distribution, sanitary installations, and hygiene education, should be implemented.
这项粪便研究旨在确定刚果民主共和国东部基利巴地区人体肠道寄生虫的流行情况。2014年4月至6月收集了602名年龄在9至20岁的学童的粪便并进行检查。直接分析辅以加藤法和里奇法。基利巴地区学龄儿童肠道寄生虫病的总体患病率为91.4%[95%置信区间：87.6 - 94.3%]。蠕虫病的发生率很高，为73.8%（95%置信区间：68.4 - 78.6%），原生动物的发生率达到32.9%（95%置信区间：27.7 - 38.6%）。女孩感染的频率高于男孩。17 - 20岁年龄组的感染率最高（97.7%），但在所研究的年龄组之间未观察到统计学上的显著差异。最常见的寄生虫种类为：曼氏血吸虫（30.6%）、粪类圆线虫（21.3%）、溶组织内阿米巴（17.6%）、肠滴虫（14.6%）、十二指肠钩口线虫（13.6%）、蛔虫（12.6%）、鞭虫（9.0%）、牛带绦虫（6.6%）和蓝氏贾第鞭毛虫（5.0%）。这项调查表明这些粪便感染极为常见。应实施包括供水、卫生设施和健康教育在内的预防措施。
