Abstract

The phylogenetic relationships of all species in the genus , and other gram-negative bacteria were determined by comparison of partial 16S ribosomal ribonucleic acid sequences. The results of this study indicate that species now recognized in the genus make up three separate ribosomal ribonucleic acid sequence homology groups. Homology group I contains the following true species: (type species), , and “” (CNW strains). “,” “Campylobacter fennelliae,” , and constitute homology group II. Homology group III contains and . We consider the three homology groups to represent separate genera. However, at present, easily determinable phenotypic characteristics needed to clearly differentiate them are not apparent. The three homology groups are only distantly related to representatives of the alpha, beta, and gamma branches of the purple bacteria, indicating that these bacteria do not belong to any previously defined branch of this phylum.
