In comparative experiments it has been possible to establish essential differences in the extent of resistance to plague in noon jerboas inhabitating the left and right banks of the Volga, and also related differences in the pathogenesis of the infection. When the subcutaneous method of infection is used the LB50 for left-bank noon jerboas exceeded the LB50 for right-bank jerboas by several dozens of thousands or hundreds of thousands of times. The geographical isolation of the right-bank and left-bank noon jerboas is not subject to doubt. In this report the effect of genetic factors on the formation of plague resistance in left-bank noon day jerboas was studied.
