A comparative study of the prevalence of Schistosoma mansoni and their intermediate host in the fishing villages of Nakiwogo and Kigungu is reported. A total of 520 inhabitants from the two villages were examined for Schistosoma mansoni. Their age varied from 4 to 40 and the infection was found to be higher at Nakiwogo 95(36.6%) than at Kigungu 40(15.4%). The snails collected were 1,345 Biomphalaria choanomphala, 237 Biomphalaria pfeifferi, 180 Bulinus (Bulinus) tropicus, 56 Bulinus (physopsis) globosus and other snails of non-medical importance like Pila ovata, Melanoides tuberculata and Bellamya species. Biomphalaria choanomphala was found to be the major intermediate host for Schistosoma mansoni in the two villages. The intermediate hosts for S. mansoni were screened for cercarial shedding, 2 Biomphalaria pfeifferi shed furcocercous cercariae and 9 Leptocercous cercariae while Biomphalaria choanomphala were an negative. The water contact activities related to infection in the two villages are discussed.
本文报道了在纳基沃戈和基贡古渔村对曼氏血吸虫及其中间宿主的流行情况进行的一项比较研究。对来自这两个村庄的520名居民进行了曼氏血吸虫检测。他们的年龄在4岁至40岁之间，结果发现纳基沃戈的感染率为95例（36.6%），高于基贡古的40例（15.4%）。采集的螺类有1345只漏斗椎实螺、237只菲氏椎实螺、180只热带泡螺、56只球拟黑螺以及其他无医学重要性的螺类，如卵形瓶螺、瘤拟黑螺和环棱螺属物种。漏斗椎实螺被发现是这两个村庄曼氏血吸虫的主要中间宿主。对曼氏血吸虫的中间宿主进行了尾蚴逸出筛查，2只菲氏椎实螺逸出了叉尾蚴和9只瘦尾蚴，而漏斗椎实螺未检测到尾蚴逸出。文中还讨论了与这两个村庄感染相关的水接触活动。
