摘要
目的掌握我市境内南盘江沿岸鼠形动物及蚤类种群分布情况,为有关决策部门应对鼠疫提供科学依据。方法采用一夜笼密法捕鼠,采集活鼠鼠体蚤后进行鼠类和蚤类鉴定,并采集鼠血清进行F1抗体检测。结果20个调查点共捕获鼠形动物121只,经鉴定为2目2科3属4种,捕获率为9.20%,其中褐家鼠占83.46%;黄胸鼠占9.92%,其它占6.61%;检获寄生蚤265匹,染蚤率为56.64%,鼠体染蚤指数为2.43。经检测120份鼠血清均为鼠疫F1抗体阴性。结论我市境内南盘江沿岸缺少足够与鼠疫密切相关的中间宿主,但仍应密切关注这一区域鼠蚤类动物种群变化情况。
Objective The population and constitution of rats and the situation of its parasitic fleas in the villages by the NanPang River side in YuXi city , prevent the damage of the plague, and to provide the science evidence for its forecast. Methods Mice were caught by night cage - caught . Rat and flea were identified after flea being caught from living rats. Collecting the serum samples from rats, and detected the F1 antibody with RIP method. Results 121 rat -like animals were caught from 20 surveillance sites, being identified to 2 orders, 2 families, 3 genera and 4 species. The capture rate was 9. 20%. We caught 265 parasitical fleas from rats, the fleas carrying rate of mice was 56. 64% and the index of fleas inflection among the mice is 2.43. F1 antibody was detected by RIP from 120 rat sera samples, the results were all negative. Conclusion The possibility of plague is litde in the region we investigated, but request more monitor of rat and its parasitic fleas.
