[The characteristics of the action of the capsular antigen of Yersinia pestis on cells from plague-susceptible and -insusceptible rodents].

The state of the functional activity of peritoneal leukocytes from different species of gerbils (Mongolian gerbils, Libyan jirds, as well as gerbils inhabiting the right and left banks of the Volga), exposed to the action of Y. pestis capsular antigen, has been found to correlate with the susceptibility of these animals to plague.
