目的掌握衢州市鼠疫历史疫区啮齿类动物分布特征,为监测及预警提供依据。方法在监测点采用笼日法捕鼠,对捕获鼠分类鉴定,并进行鼠密度、生境分布调查;用放射免疫、间接血凝及反向血凝试验检测鼠疫F1抗体、抗原,四步检验分离鼠疫菌;同时主动搜索不明原因自毙动物及开展疫情监测等以掌握鼠疫疫情情况。结果家栖鼠优势种主要为黄胸鼠和褐家鼠,野鼠主要为黑线姬鼠;其中室内、室外平均鼠密度分别为2.99%、1.20%;捕获鼠血清鼠疫F1抗体、抗原和细菌检测结果均为阴性;另外未发现自毙动物及鼠疫病例。结论衢州市啮齿类动物构成保持稳定,密度低,尚未发现动物鼠疫疫情,仍应坚持监测,及时发现异常动态,防止人间鼠疫的发生。
Objective To understand the distribution characteristics of rodents in the historic epidemic area of Quzhou plague and provide the basis for monitoring and early warning. Methods Cage method was used to catch rats at the monitoring point. The captured mice were classified and identified, and the distribution of rat density and habitat was investigated. The F1 antibody and antigen of plague were detected by radioimmunoassay, indirect hemagglutination and reverse hemagglutination test. Plague bacteria; at the same time take the initiative to search for unexplained dead animals and epidemic prevention and control to grasp the outbreak of plague. Results The predominant species of domestic habitat were Rattus flavipectus and Rattus norvegicus, the main species of them were Apodemus agrarius. The average indoor and outdoor rodent densities were 2.99% and 1.20% respectively. The detection of antibody, antigen and bacteriostasis The results were negative; the other did not find self-death animals and plague cases. Conclusion The structure of rodents in Quzhou City is stable, with low density. No outbreaks of animal plague have yet been found. Monitoring should be continued to detect abnormalities in time to prevent human plague.
