1983年判定乌鲁木齐县天格尔山北坡头屯河东岸山坡存在鼠疫疫源地以后,至1986年经细菌学判定的疫点共3个,疫点面积约3.5平方公里;在此期间自灰旱獭(M.baibacina)体分离到鼠疫菌共5株,但未能从旱獭体外寄生物中分离到鼠疫菌。1987年动物鼠疫监测的重点是,监测疫源地的空间分布范围及动物鼠疫流行动态,查明鼠疫传播媒介的种类。现将监测结果报告如下。 In 1983, it was decided that plague origin was located on the east slope of Toutun River on the northern slope of Tian’er Mountain in Urumqi County. Three epidemic points were identified by bacteriology in 1986 with an area of ​​about 3.5 square kilometers. During this period, Five strains of M. plague were isolated from M.baibacina, but Yersinia pestis could not be isolated from the marmot ectoparasite. In 1987, the focus of animal plague surveillance was to monitor the spatial distribution of foci and the epidemiology of animal plague and identify the types of plague vectors. The monitoring results are reported below.
