Abstract

DNA relatedness was evaluated among the type strains of and the 11 species which were designated as subjective synonyms in volume 4 of Three subspecies, five putative strains of , and the type strain of “” were also included in the present study. The 21 strains studied segregated into 14 clusters (average linkage) when grouped at >70% DNA relatedness, including 10 single-member clusters. subsp. subsp. , and were found to be synonymous at >79% DNA relatedness. The other clusters, on the basis of their relatively low DNA relatedness to , appear to be valid species rather than subjective synonyms of
