目的初步了解鼠类在武汉市感染性钉螺形成中的作用。方法用鼠夹法捕获野鼠,调查武汉市部分江滩的鼠类分布,对捕获鼠进行分类并解剖观察血吸虫感染情况。结果共放置鼠夹340个,捕获鼠类34只,均为黑线姬鼠。经解剖未发现血吸虫感染。结论鼠类在长江武汉段江滩感染性钉螺形成中的作用较小。 Objective To understand the role of rodents in the formation of infectious snails in Wuhan. Methods The rat was captured by the mouse clamp method. The distribution of the rats in some riverside of Wuhan was investigated. The captured mice were classified and dissected to observe the infection of schistosomiasis. Results A total of 340 mousetraps were placed and 34 mice were captured, all of which were Apodemus agrarius. Schistosoma infection was not found after dissection.
