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.

D010930 Plague An acute infectious disease caused by YERSINIA PESTIS that affects humans, wild rodents, and their ectoparasites. This condition persists due to its firm entrenchment in sylvatic rodent-flea ecosystems throughout the world. Bubonic plague is the most common form. Bubonic Plague,Meningeal Plague,Pneumonic Plague,Pulmonic Plague,Black Death,Black Plague,Septicemic Plague,Yersinia pestis Infection
D004197 Disease Reservoirs Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks. Humans may serve both as disease reservoirs and carriers.
