在流水中进行哨鼠疫水测定，近三年共测定６次，放哨鼠１３８只，解剖１１５只，阳性１０９只，感染率９４．８％，共检获血吸虫８４１８条，阳性鼠平均每鼠感染７７．２条。在内河，哨鼠感染率９８．１％。（５２／５３），共检获血吸虫７５２６条；江滩１００％（５０／５０），８１６条；长江（南京长江大桥附近）５８·３％（７／１２），７６条。哨鼠疫水测定结果表明，血吸虫感染仍较重，疫区人民应加强防范。 Sentinel water was measured in running water in the past three years, a total of 6 measurements were made, 138 rats were sentineted, 115 were dissected, 109 were positive, the infection rate was 94.8%. A total of 8418 schistosoma were seized, and the average number of positive mice was 77 .2 articles. In the river, the infection rate of sentinel 98.1%. (52/53).
