摘要: 为查清我省东部山区清原县肾综合征出血热(HFRS)自然疫源地宿主动物和恙螨分布情况,于1986年3月至1987年2月进行了现场调查。结果:(1)捕鼠199只,隶属7属8种,其中黑线姬鼠占54.27%,为优势种,而且带螨率较高(75.0%),鼠密度在6、8和10~11月先后出现3个高峰,以8月份最高;(2)收集恙螨1791只,其中日本新恙螨占50.98%,为优势种,季节高峰在10月。结论:日本新恙螨在该疫源地HFRS传播中可能起重要作用,这为进一步开展病毒学研究提供了线索。

Abstract: The survey of the host animals and chigger mite from natural focis of HFRS was carriedout from March, 1986 to February, 1987 in Qingyuan county east mountain areas of Liaoning province.1.199 rodents were caught.They belonged to eight species, seven genera.Among them, Apodemusagrarius was the predominant species which was 54.27 percent.The rate with mites was high (75%).There appeared 3 peaks of rodent density in June, August and October to November.The highest one wasin August.2.1791 chigger mites were collected.Among them, Neotrombicula japonica was the dominantspecies, whose constituent rate was 50, 98 percent.The density of the mite was high in October.3.Neotrombicula japonica may play an important role in spreading HFRS in the fool.This providethe clue for further virology research.
