摘要
本次调查区位于北纬40°10′～44°43′,东经119°51′～120°25′。调查期间从达乌尔黄鼠 Citellus dauricus、方形黄鼠蚤松江亚种 Citellophilus tesquorum sungaris及角尖眼蚤指名亚种O phthalmopsylla prae fecta prae fecta中共分离出27株鼠疫杆菌。 疫点位于北纬40°18′～40°37′,东经120°10′～120°20′。达乌尔黄鼠的鼠疫F1抗体阳性2份,阳性率为0.13％,从而首次判定调查区内存在鼠疫自然疫源地。
The surveyed areas were situated in 40° 10-44° 43' N, 119° 51' -120° 25' E. Twenty-seven strains of plague bacilli were isolated from Citellus dauricus, Citellophilus tesquorum sungaris and Ophthalmopsylla praefecta praefecta. Positive rate of plague Fl
antibody was 0.13% for sera of Citellus dauricus. The investigation, therefore, supplied evidence for the first time that natural plague foci existed in the surveyed areas.
