To differentiate the plague and pseudotuberculosis microbes a highly specific and simple reaction is suggested. The reaction consists in carbon agglomeration with the use of immune serum, containing antibodies against the first fraction. In investigating 32 P. pestis strains three strains were revealed which formed no first fraction and were avirulent. Of the 50 P. pseudotuberculosis strains three contained the first fraction. All these cultures proved to be avirulent, were isolated from rats in the same locality. The problem of the species to which they belong requires further study. Author
