目的 :进一步了解鼠类自然感染日本血吸虫的情况。方法 :按常规方法检查。结果 :鼠类总感染率为 1.73% ( 31/ 1790 ) ,自然感染的鼠类有黄胸鼠、褐家鼠、斯氏鼠及大绒鼠 ,感染率分别为 2 .87%、0 .62 %、2 .94%及 2 4.14 % ;4种鼠在居民区、农耕区及果园的感染率为 2 .10 %、3.85 %和 2 .5 6% ,三者间差异无显著性 ;雌雄性间感染率差异亦无显著性 ,但年龄组中两性有别 ,即各年龄组中 ,以成体组及老体组感染率高。感染度及排卵量以大绒鼠居高 ,与其具有的生物学特性有关。感染鼠类的分布与阳性钉螺的存在及其感染率高低密切相关。结论 :4种鼠在洱源县疫区应属日本血吸虫的保虫宿主及血吸虫病的传染源之一 ;从同期对人、畜感染血吸虫的调查结果分析 ,在山区血吸虫病的传播与大绒鼠等有一定关系 ,但居次要地位。
Objectives: To further understand the natural infection of Schistosoma japonicum in mice. Method: check by conventional methods. Results: The total infection rate of rats was 1.73% (31/1790). The naturally infected mice were Rattus flavipectum, Rattus norvegicus, Sipes and Mudgery, the infection rates were 2.87% and 0.62 %, 2.94% and 2.14% respectively. The infection rates of 4 kinds of mice in residential area, farming area and orchard were 2.10%, 3.85% and 2.56%, respectively. There was no significant difference among them There were no significant differences in the infection rates between the two groups, but the gender differences between the age groups, that is, in all age groups, the adult group and the old group had a high infection rate. Infection and ovulation amount of the giant mongoose Habitat, with its biological characteristics. The distribution of infected mice is closely related to the existence of positive snails and the infection rate. Conclusions: Four kinds of mice should be one of the sources of Schistosoma japonicum host and schistosomiasis in the endemic area of Eryuan County. From the survey results of schistosomiasis infection in humans and animals in the same period, There is a certain relationship between rats, but the secondary position.
