目的了解高海拔地区肾综合征出血热(HFRS)宿主动物特点,确定疫源地类型,分析该病的流行特点,为防治提供科学依据。方法采用铁板鼠夹,花生米作诱饵,晚放晨收,开展室内外监测。收集鼠肺和鼠血,用间接免疫荧光法检测鼠肺中抗原和鼠血中抗体。结果 10年共投放鼠夹40480夹次,捕鼠4621只,隶属2目3科7属8种。主要带病毒鼠有褐家鼠、黄胸鼠、小家鼠、川西白腹鼠,室内捕捉的高山姬鼠。结论盐源县目前仍为家鼠型HFRS疫区,宿主动物种类多且复杂;川西白腹鼠为高海拔HFRS宿主动物之一。
Objective To understand the characteristics of host animal of hemorrhagic fever with renal syndrome (HFRS) in high altitude area, determine the type of foci, analyze the epidemiological characteristics of the disease and provide a scientific basis for prevention and treatment. Methods Tieban rattrap and peanut were used as bait, which were put in late morning and closed for indoor and outdoor monitoring. Mouse lung and mouse blood were collected, and antigens from mouse lung and mouse blood were detected by indirect immunofluorescence. Results A total of 40480 clips were placed in the mouse clip for 10 years, 4621 mice were caught, belonging to 8 orders, 7 genera, 2 orders, 3 families. The main mice with Rattus norvegicus, Rattus flavipectus, Mus musculus, Kawanishi abdominal mouse, indoor capture of alpine Apodemus. Conclusion Yanyuan County is still home-born HFRS epidemic area with many species of host animals and complicated host animals. Baibabs are one of the high altitude HFRS hosts.
