To obtain a better understanding of the possible influence of swamp rice farming on the patterns of Schistosoma mansoni and Schistosoma haematobium infections, the populations of two communities in rural liberia were studied. In one village, Balama (population of 435), swamp rice farms were initiated six years before the survey; in the other nearby community, Gbarta (population of 216), swamp rice farms had not yet been initiated. The prevalence of S. mansoni infection in Balama was 87% vs. 9% in Gbarta (P less than 0.01). The geometric and arithmetic mean egg counts for all infected subjects in Balama were respectively 263 and 671/g feces. in Gbarta, the geometric and arithmetic mean egg counts were 150 and 129/g feces. S. haematobium eggs were detected in 42% of subjects in Balama vs. 11% in Gbarta (P less than 0.01). Hematuria correlated with the presence of S. haematobium eggs in urine. These data indicate that there is a significantly higher prevalence and intensity of schistosomiasis mansoni and haematobia in a community where swamp rice farming has been utilized for 6 years compared to a nearby village where this water irrigation and drainage practice has not yet been implemented.
为了更好地了解沼泽稻种植对曼氏血吸虫和埃及血吸虫感染模式的可能影响，对利比里亚农村两个社区的人群进行了研究。在一个村庄巴拉马（人口435人），在调查前六年开始了沼泽稻种植；在附近的另一个社区加巴尔塔（人口216人），尚未开始沼泽稻种植。巴拉马的曼氏血吸虫感染率为87%，而加巴尔塔为9%（P<0.01）。巴拉马所有感染受试者的几何平均和算术平均虫卵计数分别为每克粪便263个和671个。在加巴尔塔，几何平均和算术平均虫卵计数分别为每克粪便150个和129个。在巴拉马，42%的受试者检测到埃及血吸虫卵，而在加巴尔塔为11%（P<0.01）。血尿与尿中埃及血吸虫卵的存在相关。这些数据表明，与附近尚未实施这种水灌溉和排水做法的村庄相比，在一个已经利用沼泽稻种植6年的社区中，曼氏血吸虫病和埃及血吸虫病的患病率和感染强度明显更高。
