A Serological Study of Strains ofAlcaligenes radiobacterandPhytomonas tumefaciensin the “M” and “S” Phases

Abstract
An investigation was made of the serol. relationship of Alcaligenes radiobacter and Phytomonas tumefaciens with the use of agglutination and agglutinin absorption techniques employed in the study of typical strains in the Dawson "M" and "S" phases. In the strains under study, A. radiobacter and P. tumefaciens differed serologically in the "M" phases. The same strains are antigenically identical in the "S" phase, as indicated by complete reciprocal agglutinin absorption.
