The paper analyzes the change that occurred in the habitat of the causative agent of plague in its Gorno-Altaisk natural focus in 1961 to 2012. Since 1961 when the plague microbe was found to come from the southern slopes of the Saylyugem mountain range, which are located in Mongolia, to the northern slopes situated in Russia, a gradual expansion of the habitat of Yersenia pestis subsp. altaica had commenced in South-Eastern Altai. During the considered period, the area where epizootic manifestations were registered showed an 11-fold increase. In most cases, the spread of the plague pathogen within the focus was natural and occurred in the successive and closely related settlements of Mongolian pikas (Ochotona pallasi). By now, the plague microbe has been widely distributed in three populations of this small animal, which inhabit the territory of South-Eastern Altai.
本文分析了1961年至2012年期间，鼠疫病原体在戈尔诺-阿尔泰斯克自然疫源地的栖息地变化情况。自1961年发现鼠疫杆菌来自蒙古国境内萨彦岭山脉南坡，延伸至俄罗斯境内北坡以来，东南阿尔泰地区的高海拔鼠疫耶尔森菌栖息地开始逐渐扩大。在研究期间，有动物流行病表现的区域面积增加了11倍。在大多数情况下，鼠疫病原体在疫源地内的传播是自然发生的，且发生在蒙古鼠兔（高原鼠兔）连续且密切相关的聚居地。目前，鼠疫杆菌已在这种栖息于东南阿尔泰地区的小型动物的三个种群中广泛分布。
