During an investigation of 346 strains of P. pestis with the agglutinating sera of bacteria of the intestinal group a positive result was obtained in 31 cases 8.9. Plague serum agglutinated 46 cultures of enterobacteria from various species out of 165 checked 27.8. In the tests of the cross reactions of agglutination and antibody adsorption, the presence of common antigenic components was supported in some of the strains of the plague microbe and enterobacteria. The presence in strains of P. pestis of antigens which are inherent to bacteria of the intestinal group was not connected with other biological properties of the cultures, and the stated feature, judging by the data obtained, cannot be used for the intraspecies grouping of strains of the plague microbe.
