From a common ancestor, Streptococcus pneumoniae and Streptococcus mitis evolved in
parallel into one of the most important pathogens and a mutualistic colonizer of humans …

The bacterium Streptococcus pneumoniae is one of the leading causes of fatal infections
affecting humans. Intriguingly, phylogenetic analysis shows that the species constitutes one …

Streptococcus pseudopneumoniae (SPPN) is a recently described species of the viridans
group streptococci (VGS). Although the pathogenic potential of S. pseudopneumoniae …

Streptococcus pseudopneumoniae is a close relative of the major human pathogen S.
pneumoniae. It is increasingly associated with lower-respiratory-tract infections (LRTI) and a …

Taxonomic and phylogenetic relationships of Streptococcus mitis and Streptococcus oralis
have been difficult to establish biochemically and genetically. We used core-genome …

Streptococcus pneumoniae is a member of the Mitis group of streptococci which, according
to 16S rRNA-sequence based phylogenetic reconstruction, includes 12 species. While other …

We sequenced the genomes of 3,615 strains of serotype Emm protein 1 (M1) group A
Streptococcus to unravel the nature and timing of molecular events contributing to the …

The genetic variability in bacterial species is much larger than in other kingdoms of life. The
gene content between pairs of isolates can diverge by as much as 30% in species like …

Correct identifications of isolates and strains of the Mitis-Group of the genus Streptococcus
are particularly difficult, due to high genetic similarity, resulting from horizontal gene transfer …

Abstract Background The human pathogen Streptococcus pyogenes, or group A
Streptococcus, is responsible for mild infections to life-threatening diseases. To facilitate the …
