The Mitis group of the genus Streptococcus currently comprises 20 species with validly
published names, including the pathogen S. pneumoniae. They have been the subject of …

Genomic, taxonomic and biochemical studies were performed on two strains of α-haemolytic
streptococci that showed them to be clustered with major members of the Streptococcus …

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

We recently described the novel species Streptococcus tigurinus sp. nov. belonging to the
Streptococcus mitis group. The type strain AZ_3aT of S. tigurinus was originally isolated from …

Taxonomic studies were performed on eight strains of α-haemolytic streptococci that showed
very low DNA-DNA hybridization similarity values with all established members of the mitis …

Five streptococcal strains were isolated from dental plaque and saliva of caries-free
humans. The cells were Gram-positive, non-spore-forming, non-motile cocci that were …

Alternative phylogenies for the genus Streptococcus have been proposed due to uncertainty
about the among-species group relationships. Here, we performed a phylogenetic analysis …

The Anginosus group of the genus Streptococcus has been the subject of much taxonomic
confusion, which has hampered the full appreciation of its clinical significance. The purpose …

A numerical taxonomic survey of numerous strains of streptococci showed the presence of
two clusters of strains that are distinct from the presently named species of Streptococcus …

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 …
