It is considered that the passive hemagglutination reaction is completely suitable for directed searches for the plague microbe and should enter into the complex of methods for the field diagnosis of plague. It should be carried out by qualified specialists in a known enzootic territory, in various phases of the epizootic process and with variations in the volume of rodents investigated for the presence of the plague microbe and their sera for the presence of antibodies. A similar type of investigations will apparently lead in the end result to an establishment of the necessary quantitative forms for the investigation of carriers for the isolation of the plague causative agent in various phases of the epizootic process and particularly in the period of depression.
