Relationships among selected species of viridans streptococci were studied by using
deoxyribonucleic acid (DNA)-DNA hybridization and biochemical and serological tests. The …

One hundred reference strains representing all species belonging to the different
phylogenetic lineages of the viridans streptococci were examined by means of one …

The rapid ID 32 Strep system (bioMérieux, Marcy l'Etoile, France) was evaluated for its ability
to identify 21 species of viridans group streptococci; results were compared with DNA-DNA …

The utility of PCR analysis of transfer DNA intergenic spacer length polymorphism (tDNA-
ILP) for the identification to the species level of clinically relevant viridans streptococci was …

We examined a collection of 151 strains of the viridans type of streptococci, which were
isolated mainly from human oral cavities and included several reference strains, in an …

Based on the genetic analysis of 20 reference strains, we describe an approach using the
sequencing of 2 housekeeping genes, zwf and gki, to identify members of the mitis …

The genetic relationships among 33 streptococci that were identified as Streptococcus
salivarius or Streptococcus bovis and were isolated from humans were determined by …

Nucleic acid hybridization studies together with a chemical cell wall analysis and
physiological data indicated that some strains designated as Streptococcus sanguis II …

Twenty-five strains resembling 'Streptococcus milleri'were compared by DNA-DNA
hybridization, by whole-cell-derived polypeptide patterns on SDS-PAGE, and by …

The taxonomic relationships among selected species of 'pyogenic'and 'viridans' streptococci
were examined using DNA-DNA hybridization, DNA base composition and biochemical …
