[Is not plague a "protonosis"? (the role of Protozoa in the epizootiology of plague)].
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.
