为进一步分析四川省是否存在鼠疫自然疫源地,1984～1986年对该省西北部8个县的犬和喜马拉雅旱獭血清6226份应用放射免疫沉淀试验(RIP)进行了鼠疫血清学检查,查出阳性39份,结合既往流行史和动物、昆虫等资料,初步认为石渠、色达县境内旱獭种群中存在鼠疫,在德格、甘孜、炉霍、若尔盖、阿坝的旱獭中可能也有存在。对壤塘的监测结果虽然全为阴性,但考虑监测样品少和该地有疑似鼠疫病史,故有待继续监测。
In order to further analyze the existence of plague natural foci in Sichuan Province, from 1984 to 1986, serological tests on plague were performed by radioimmunoprecipitation assay (RIP) in 6226 serogroups of dogs and Himalayan Marmota in the eight counties in the northwestern part of the province. 39 were positive. According to the past epidemic history, animals, insects and other data, the plague was preliminarily thought to exist in the population of marmot in Shiqu and Seda County, and may also exist in the marmots of Dege, Garze, Luhuo, Ruoergai and Aba. Although the results of the monitoring of the soil ponds are all negative, there are few samples to be monitored and there is a suspected history of plague in the area, so the monitoring needs to be continued.
