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 To understand the distribution of rodents and fleas in Nanpanjiang River in our city and provide a scientific basis for the relevant decision-making departments to deal with the plague. Methods One night cage method was used to catch rats. The fleas of living mice were collected to identify the mice and fleas, and the serum of mice was collected to test the F1 antibody. Results Totally 121 mouse-shaped animals were captured in 20 investigation sites and 4 species were identified as 3 orders, 2 orders, 2 families, and capture rate was 9.20%, of which Rattus norvegicus accounted for 83.46%, Rattus flavipectus accounted for 9.92% and others accounted for 6.61% ; 265 parasitic fleas were seized, the rate of stained flea was 56.64%, and the index of stained flea in rats was 2.43. After testing 120 mouse serum were plague F1 antibody negative. Conclusion There are not enough intermediate hosts in the Nanpan River along the plains in our city. However, close attention should be paid to the population changes of the fleas in this area.
