【摘要】：目的探讨中国鼠疫菌株生化性状及地理分布特征。方法采用常规方法,研究我国现有11种类型的鼠疫自然疫源地2 370株鼠疫菌酵解麦芽糖、鼠李糖、蜜二糖、阿胶糖、甘油及脱氮反应的变化。结果根据测定结果,与地理分布生物群落联系起来,可将中国鼠疫自然疫源地鼠疫菌分为新的17个生化型:青藏高原青海田鼠鼠疫自然疫源地分离的鼠疫菌定名为川青高原型,新疆准噶尔盆地大沙鼠鼠疫疫源地鼠疫菌定名为准噶尔型,云南省玉龙县大绒鼠、齐氏姬鼠分离暂定名为玉龙型。青藏高原喜马拉雅旱獭鼠疫自然疫源地生化性状较为复杂,含5种类型生化型,其中藏南地区1983年后新增加了27个疫源县,本研究发现青藏高原型菌株不仅只分部在藏北高原,在藏南地区已有分布,且岗底斯山型菌株原来只分布在西南地区的仲巴、普兰,现已延伸到藏南地区。还发现一些鼠疫自然疫源地鼠疫菌生化特性有交串现象,如云南省家、野鼠鼠疫自然疫源地鼠疫菌,内蒙古高原长爪沙鼠、达乌尔黄鼠鼠疫自然疫源地。结论中国鼠疫菌对糖酵解特性较稳定,鼠疫菌生化型在各疫源地呈明显的地区性分布,与主要宿主、地理气候条件、植被等密切相关,分为17个生化型。
[Abstract]:Objective to study the biochemical characters and geographical distribution of Yersinia pestis strains in China. Methods routine methods were used to study the changes of glycolytic maltose, rhamnose, honey disaccharide, gelatin sugar, glycerol and denitrification of 2 370 strains of Yersinia pestis in 11 types of plague natural foci in China. Results according to the results, the Yersinia pestis in the natural foci of plague in China can be divided into 17 new biochemical types, which are related to the geographical distribution of biota. The Yersinia pestis isolated from the natural foci of the plague in Qinghai Province on the Qinghai-Tibet Plateau is named as the Chuan Qing Plateau type of Yersinia pestis. The Yersinia pestis in the plague foci in Junggar Basin of Xinjiang was named as Junggar type, Yulong County, Yunnan Province, and Qiji mice were tentatively named as Yulong type. The biochemical characteristics of plague natural foci of Marmota Himalayas in Qinghai-Tibet Plateau are more complex, including 5 types of biochemical types, among which 27 new epidemic source counties have been added since 1983 in southern Tibet. This study found that Qinghai-Xizang plateau type strains are not only distributed in the northern Tibetan Plateau. It has been distributed in the south of Tibet, and only distributed in Zhongba and Plan in southwest China, and now it has been extended to the south of Tibet. Some Yersinia pestis in natural foci of plague, such as Yersinia pestis in Yunnan Province, Yersinia pestis in Yersinia pestis natural foci in Inner Mongolia Plateau, Daour yellow rat plague natural foci, were also found. Conclusion the glycolysis characteristics of Yersinia pestis in China are stable. The biochemical types of Yersinia pestis are obviously distributed in various foci, which are closely related to the main hosts, geographical climate conditions and vegetation, and can be divided into 17 biochemical types.
