在尼日利亚西南部奥贡州的一个城市和一些农村社区对学龄儿童的肠道蠕虫和血吸虫病进行了调查。在2005年6月至2006年11月期间，使用直接涂片和盐水浓缩法检查了1 059名3-18岁受试者（524名男性，535名女性）的粪便样本。合并感染率为66.2%。蛔虫感染率最高（53.4%）（P < 0.001），其次为钩虫（17.8%）、鞭虫（10.4%）、带绦虫（9.6%）、曼氏血吸虫（2.3%）、粪类圆线虫（0.7%）、埃及血吸虫（0.6%）和蛲虫（0.3%）。A.蛔虫，钩虫，带绦虫，S. mansoni和S.城市中心区粪尿菌与农村社区粪尿菌无显著性差异（P > 0.05）。结果表明，A.市区和农村居民区的蛔虫比分别为13：1和3.7：1。男女各寄生虫感染率无显著性差异（P > 0.05）。A.蛔虫随年龄增长而明显增多（P < 0.001）。最常见的双重感染是蛔虫和钩虫，而最常见的三重感染是蛔虫，钩虫和鞭虫。这项研究表明，需要紧急干预计划，对肠道蠕虫病和血吸虫病在研究领域。
Intestinal helminths and schistosomiasis among school children were investigated in an urban and some rural communities of Ogun State, southwest Nigeria. Fecal samples of 1,059 subjects (524 males, 535 females) aged 3-18 years were examined using direct smear and brine concentration methods between June 2005 and November 2006. The pooled prevalence of infection was 66.2%. Ascaris lumbricoides showed the highest prevalence (53.4%) (P < 0.001) followed by hookworms (17.8%), Trichuris trichiura (10.4%), Taenia sp. (9.6%), Schistosoma mansoni (2.3%), Strongyloides stercoralis (0.7%), Schistosoma haematobium (0.6%), and Enterobius vermicularis (0.3%). The prevalences of A. lumbricoides, hookworms, Taenia sp., S. mansoni, and S. stercoralis in the urban centre were similar (P > 0.05) to those in the rural communities. The fertile and infertile egg ratios of A. lumbricoides in the urban centre and the rural communities were 13: 1 and 3.7: 1, respectively. Each helminth had similar prevalences among both genders (P > 0.05). The prevalence of A. lumbricoides increased significantly with age (P < 0.001). The commonest double infections were Ascaris and hookworms, while the commonest triple infections were Ascaris, hookworms, and Trichuris. The study demonstrates the need for urgent intervention programmes against intestinal helminthiases and schistosomiasis in the study area.
