对外高加索鼠疫自然疫源地两种沙土鼠进行了研究。外高加索山麓平原鼠疫自然疫源地的主要携带者是红尾沙土鼠和维拉格拉道夫沙土鼠。消灭主要携带者的效果仅限于在短期内,而在停止消灭后的4～7年沙土鼠的数量就恢复。控制工作的意义只是减少啮齿类的数量,并使疫源性的活性保持在低的水平。但是通过消灭宿主在疫源地内消灭细菌用现代的有关防治
Two species of gerbils in the natural foci of the outer Caucasus have been studied. The main carriers of the natural foci of the Plains of the Transcaucasus foothills are red-tailed gerbils and Vilagradorev Gerbils. The effect of eradicating the main carriers is limited to short periods, and the number of gerbils recovered between 4 and 7 years after the cessation of extinction. The significance of control efforts is only to reduce the number of rodents and to keep foci of activity low. However, by eradicating the host, bacteria are eliminated in the foci with the modern control measures
