摘要： 目的 分析1993~2013年南京市21年来钉螺感染率与哨鼠血吸虫感染情况以及两者之间的相关性，为制定防治措施提供科学依据。 方法 1993~2013年每年春季采用系统抽样结合环境抽查法开展螺情调查，并在同一时间段采取小白鼠接触法对水体的血吸虫感染性进行现场检测。 结果 钉螺感染率、感染性钉螺面积总体呈逐年下降趋势，2009年至今未发现阳性螺点；哨鼠感染率1998年以前高达100%，2008年至今哨鼠感染率均为0。两者变化趋势一致，存在显著的正相关，相关系数rs为0.726，有统计学意义（P=0.000）。 结论 加大综合防治力度，控制感染性钉螺，依然是该市控制血吸虫病流行的有效防治措施。

Abstract:

Objective  To analyze the infection rate of snails and sentinel mice in Nanjing area from 1993 through 2013, and examine the relationship between the two host infection for scientific prevention and control.  Methods In annual spring season of 1993 through 2013, we conducted surveys on the snail prevalence using systematic and environmental sampling methods, and simultaneously tested the schistosome infectivity within the water body by sentinel mouse contact. Results The rate of infected snails and areas with positive snails tended to decline in general, and no infected snails were reported since 2009. The infection rate for sentinel mouse was 100% before 1998, yet dropped to zero since 2008. The infection rate of snails was positively correlated with sentinel mouse infection(rs=0.726, P=0.000). Conclusion Comprehensively enhanced measures together with control of the infectious snails shall be effective measures in following prevention of schistosomiasis in Nanjing area.
