The classification of the oral streptococci has long remained a difficult area of streptococcal
taxonomy. This article reviews the current classification of these bacteria into four species …

The contribution of enzyme tests to the accurate and rapid routine identification of gram-
positive cocci is introduced. The current taxonomy of the genera of aerobic and facultatively …

The associations of Streptococcus intermedius, S. constellatus, and S. anginosus (the three
species of the S. milleri group) with clinical infections and sites of isolation were investigated …

A biochemical scheme was developed by which strains of Streptococcus constellatus,
Streptococcus intermedius, and Streptococcus anginosus can reliably be distinguished from …

Recently published taxonomic studies of viridans streptococci have resulted in several
changes in the nomenclature and definition of oral streptococcal species. With this …

Penicillin‐resistant strains of Streptococcus pneumoniae possess forms of penicillin‐binding
proteins (PBPs) that have a low affinity for penicillin compared to those from penicillin …

Strains currently classified as Streptococcus anginosus include strains previously identified
as Streptococcus constellatus (Prevot 1924) Holdeman and Moore 1974, Streptococcus …

The partial 16S rRNA sequences of 24 Streptococcus species were determined by reverse
transcription. A comparative analysis of these sequences and the sequences of seven …

A collection of strains representing all the currently recognised species of oral or viridans
streptococci (Streptococcus sanguis, S. parasanguis, S. gordonii, S. oralis, S. mitis, S …

A novel cytotoxin (intermedilysin) specific for human cells was identified as a cytolytic factor
of Streptococcus intermedius UNS46 isolated from a human liver abscess. Intermedilysin …
