The author expounds the idea that soil protozoa, whose vegetative forms and cysts can harbor the plague agent for fairly prolonged periods of time, can be a major player in the epizootiology of plague. It is also postulated that the symbiotic protozoa of the digestive tract of rodents and lagomorpha can also be a reservoir of the plague agent. If this is so, among apparent epizootic cycles in mammalians in wild plague foci one should look for Yersinia pestis in the protozoa from the burrows of their primary and secondary carriers. Because parasitism of bacteria in one-celled animals is essentially epizootic, plague epizootics are presumed to be a permanent process.
作者阐述了这样一种观点，即土壤原生动物，其营养体形式和包囊可在相当长的时间内携带鼠疫病原体，可能是鼠疫动物流行病学中的一个主要因素。还推测啮齿动物和兔形目动物消化道中的共生原生动物也可能是鼠疫病原体的储存宿主。如果是这样，在野生鼠疫疫源地哺乳动物明显的动物流行病循环中，应该从其主要和次要宿主的洞穴中的原生动物中寻找鼠疫耶尔森菌。由于细菌在单细胞动物中的寄生本质上是动物流行病，鼠疫动物流行病被认为是一个持续的过程。
