云南的鼠疫疫源地分为野鼠鼠疫疫源地和家鼠鼠疫疫源地。野鼠鼠疫疫源地分布于滇西纵谷省东北部及金沙江流域山地峡谷省西缘约N26°～27°,E98°～100°30′,海拔2000～3500米,该疫源地包括三个景观带:Ⅰ.平坝居民区及农田景观带,Ⅱ.中山云南松林及林间耕地景观带,Ⅲ.高山暗针叶林景观带,主要宿主为大绒鼠和齐氏姬鼠,主要媒介为方叶栉眼蚤和特新蚤指名亚种;家鼠鼠疫疫源地分布于N23°40′～25°30′,E97°31′～99°20′,地貌为峡谷与中低山相间,西部和南部多宽谷,跨越滇西纵谷省及南部山地省,疫点主要分布在平坝居民区及农耕区,在毗连的山区居民点或山间耕地亦检出过疫点,家鼠疫源地的主要宿主为黄胸鼠,主要媒介昆虫为印鼠客蚤和缓慢细蚤。另外,作者从人间鼠疫的规律,地理发生学和南鼠疫疫源地鼠疫菌株抗原的一致性,以及鼠疫菌的单向变异等分析推论,认为云南家鼠鼠疫疫源地源于野鼠鼠疫疫源地。
Plague foci in Yunnan Province are divided into rodent plague foci and house mouse plague foci. Husky plague foci located in northeastern Yunnan Rift Valley Province and the Jinsha River valley mountain valley about the western edge of N26 ° ~ 27 °, E98 ° ~ 100 ° 30 ’, elevation of 2000 ~ 3500 meters, the source of the three A landscape with: Ⅰ. Pingba residential area and farmland landscape, Ⅱ. Zhongshan pine forests and forestland landscape belt, Ⅲ. Alpine dark coniferous forest landscape belt, the main host for the wallaby and Qi mice, mainly The vectors are named subspecies of the genus Tetraselmis and the new flea. The plague foci of domestic rats are distributed between N23 ° 40 ’~ 25 ° 30’ and E97 ° 31 ’~ 99 ° 20’ Inter-regional, western and southern wide valleys, across the western Yunnan Rift Valley Province and the southern mountain province, the epidemic is mainly located in Pingba residential and agricultural areas, in the adjoining mountainous settlements or mountain farmland has also been detected in the epidemic, Rattus flavipectus is the main host for Rattus flavipectus, and the major vector insects are Rattus norvegicus and Sophisticated Fleas. In addition, the author from the rules of human plague, geography and South plague origin of plague strains of antigen consistency, and Y. pestis unilateral mutation analysis that the plague originated in Yunnan wild rats plague origin Ground
