1986年,我们自云南省盈江县家鼠鼠疫疫源地内,从自毙黄胸鼠体外寄生蚤缓慢细蚤中分离到一株强毒鼠疫菌 No1352株。经鉴定,该株具有F1、VW、PI、Pgm及C毒力因子,能致死豚鼠及小白鼠,并酵解葡萄糖、阿胶糖、麦芽糖和水杨素,不酵解鼠李糖、乳糖、蔗糖、密二糖、甘油、山梨醇和松三糖,脱氮及硝化阴性,甲基红反应阳性、VP反应阴性,不产生靛基质,不利用尿素,能产生硫化氢。糖醇酵 In 1986, we collected a strain of virulent Yersinia pestis strain No1352 from the slow-feeding flea of ​​the ectoparasitoid flea of ​​self-immigrated Rattus flavipectus in Yingjiang County, Yunnan Province. It has been identified that the strain has F1, VW, PI, Pgm and C virulence factors and can kill guinea pigs and mice, and also can degrade glucose, gelatin, maltose and saligenin without ruthenium, lactose, sucrose , Dextrose, glycerol, sorbitol and melezitose, denitrification and nitrification negative, methyl red reaction positive, VP negative reaction, does not produce indigo, do not use urea, can produce hydrogen sulfide.
