title: [Differences between two populations of Citellophilus tesquorum altaicus from the Tuva natural focus of plague].
abstract: Citellophilus tesquorum altaicus fleas from two natural (Karginsky and Barlyksky) populations have been studied. There are differences between the fleas of these populations in susceptibility to plague microbe. The adaptability and abundance of the causative organism in the body are higher in the fleas of the Barlyksky population. The sizes of the head are significantly higher in the females of the Karginsky population. There are no differences in this index between males. According to all 5 studies signs of chaetotaxia, the chaeta abundance is greater in both females and males of the Karginsky population. The fluctuating asymmetry is higher in the Barlyksky fleas that are more susceptible to the studied type of the causative agent of plague.
