目的了解日照平原地区鼠类种群、分布及鼠类携带汉坦病毒情况,指导当地流行性出血热防控工作。方法2014年5月—2015年4月,在日照平原区域选择8个监测点,采用夹夜法和笼夜法调查,对捕获的鼠类进行鼠种鉴定,用RT-PCR方法检测鼠类携带汉坦病毒核酸。结果共捕获鼠类167只,包括褐家鼠、小家鼠、黑线姬鼠、黑线仓鼠和臭鼩5个鼠种。野外区域平均鼠密度为1.12%,6-8月份达高峰。捕获的5个鼠种均检测到汉坦病毒核酸,存在汉城型和汉滩型混合感染情况。居民区平均鼠密度为0.11%,7-8月份达高峰,捕获的2个鼠种未检出汉坦病毒核酸。结论日照平原野外区域鼠密度高,鼠类存在感染两个汉坦病毒型别的情况,应加强监测。
Objective To understand the distribution and distribution of rodent viruses in rodent plains and to guide the prevention and control of endemic haemorrhagic fever. Methods From May 2014 to April 2015, 8 monitoring sites were selected in the Rizhao Plain area, and the captured mice were identified by the method of clip-nocturnal night and cage-night, and the rodents were detected by RT-PCR Hantavirus nucleic acid. Results A total of 167 rodents were captured, including Rattus norvegicus, Mus musculus, Apodemus agrarius, Black hamster and Smelly boar. The average rodent density in the wild is 1.12%, reaching the peak in June-August. Hantavirus nucleic acid was detected in all the 5 murine species captured, and there was a mixed infection between Seoul-type and Hantaan-type. The average density of residents in residential areas was 0.11%, peaked in July-August, and no capture of Hantaan virus was detected in the 2 murine captured species. Conclusion In the wild area of Rizhao Plain, there is a high density of rodent viruses and two types of Hantavirus infected with rodents. Therefore, monitoring should be strengthened.
