Abstract

Experimental investigations have demonstrated that proventriculus of
Citellophilus tesquorum sungaris (population habitant in the territory of Trans-Baikal region) and
Xenopsylla cheopis (classical vector) is blocked in case of the infestation with the plague microbe strain isolated from humans in Manchuria (China) in 5,6 and 15,4 % of the instances, respectively. These ectoparasites transmit plague agent to white mice both when infected with plague microbe at the moment of clustered/group feeding, and when they have their proventriculus blocked at the moment of individual feeding. Taking into consideration ecology of the species of fleas under discussion and sensitivity of the local rodent population to plague microbe, one cannot exclude possibility of the local epizooty occurrence in the territory of Siberian and Far East regions in case of plague agent importation from China.
