Bradyrhizobium japonicum Serocluster 123 and Diversity among Member Isolates †

Abstract

Diversity was examined within a group of 79 isolates of Bradyrhizobium japonicum reactive to fluorescent antibodies (FAs) prepared against B. japonicum USDA 123. Analyses were by means of cross-adsorbed FAs, bacteriophage typing, and endonuclease restriction digest patterns. Serogroups 127 and 129 shared antigenic determinants with serogroup 123 but not with each other. Bacteriophage and DNA digest patterns reflected more common features between serogroups 123 and 127 than between 123 and 129. Serogroups 129 and 122 showed FA cross-reactivity. The term serocluster was proposed to reflect interrelationships observed among the serogroups.
