[Use of serum to thermostable toxin for identification of Yersinia pseudotuberculosis]

Serum to thermostable Y. pseudotuberculosis toxin is shown to induce agglutination of bacteria belonging to all 8 serologic variants of this species. No cross reactions with other enterobacterial species, including four Yersinia species, were detected. The results permit us recommend the antitoxic serum for identification of Y. pseudotuberculosis.
