Transfer of Streptococcus faecalis and Streptococcus faecium to the Genus Enterococcus nom. rev. as Enterococcus faecalis comb. nov. and Enterococcus faecium comb. nov.

The results of deoxyribonucleic acid-deoxyribonucleic acid and deoxyribonucleic acid-ribosomal ribonucleic acid hybridization studies demonstrated that Streptococcus faecalis and Streptococcus faecium are distantly related to the non-enterococcal streptococci (Streptococcus bovis and Streptococcus equinus) of serological group D and to other streptococci. On the basis of our results and those of previous studies, we propose that S. faecalis and S. faecium be transferred to the genus Enterococcus (ex Thiercelin and Jouhaud) nom. rev. as Enterococcus faecalis (Andrewes and Horder) comb. nov. and Enterococcus faecium (Orla-Jensen) comb. nov., respectively. A description of the genus Enterococcus nom. rev. and emended descriptions of E. faecalis and E. faecium are given.
