^aValues in italics are percent identity between 16S rRNA gene sequences from two strains. Alignments of equal length were made (nucleotides 9 to 1407 from the S85 type strain). The other values are reciprocal DNA/DNA hybridization data with the left value corresponding to use of the DNA from the organism in the first row as the probe. —, not determined.
