Abstract
Agglutination and gel diffusion tests from 12 nomenspecies of the Xanthomonas campestris group, Xanthomonas albilineans, and individual strains of Pseudomonas syringae, Pseudomonas solanacearum, Agrobacterium tumefaciens, Erwinia amylovora, Erwinia stewartii, and Corynebacterium sepedonicum indicated serological distinctiveness of Xanthomonas oryzae, a member of the X. campestris group. Heat-stable, species-specific antigens were demonstrated in X. oryzae. The serological tests also revealed that most of the Xanthomonas spp. and a few Pseudomonas and Erwinia spp. shared some of the common antigens with X. oryzae. X. albilineans, A. tumefaciens, and C. sepedonicum did not share any antigen with X. oryzae.
