Deoxyribonucleotide sequence relationships among currently recognized species (, and ) were examined by deoxyribonucleic acid (DNA) hybridization involving the hydroxyapatite batch procedures of Brenner and co-workers. The results indicated that strains from all species tested were highly related. At the stringent criterion (80°C), the relative binding of DNA to DNA was 75 ± 9%, and to DNA it was 73 ± 8%. Intraspecies binding was 93 ± 8%. Under similar conditions, the relative binding of DNA to DNA was 85 ± 9%. The various so-called species may be reconsidered as representing different subspecies belonging to a single species.
