鼠疫自然疫源地的存在取决于三种因素的存在,即啮齿类、跳蚤和病原体。其中病原体起着特殊的作用。作者指出,在他们所查到的文献中,没有看到有关从不同自然疫源地和传染源分离的鼠疫杆菌菌株对一些化学物质的抵抗性的研究著作。为此,作者对40—70年代从不同疫源地的各种啮齿类及其体外寄生物分离的某些鼠疫杆菌菌株对一些消毒剂的抵抗性进行了研究。 The existence of plague natural foci depends on the presence of three factors, rodents, fleas and pathogens. Pathogens play a special role. The authors note that in the literature they found, no research was found on the resistance of certain strains of Yersinia pestis isolated from different natural foci and sources of infection. To this end, the authors studied the resistance of some strains of Yersinia pestis isolated from various rodents and their ectoparasites from different foci in the 40-70s to some disinfectants.
