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 …

The differentiation of species within the Streptococcus mitis group has posed a problem in
the routine diagnostic microbiology laboratory for some time. It also constitutes a major …

Investigating individual variations between different isolates of group A streptococci, we
observed a close correlation between biotypes and serotypes in 46 strains from pharyngitis …

The 16S–23S rRNA internal transcribed spacer (ITS) region of several Streptococcus
thermophilus strains and some related dairy streptococci, S. macedonicus, S. salivarius and …

Reverse transcriptase sequencing of 16S rRNA of Streptococcus saccharolyticus was
performed in order to determine the phylogenetic position of this organism. On the basis of …

It is difficult to distinguish mutans streptococci on the species level, and even more so on the
subspecies level. Intact cell matrix‐assisted laser desorption/ionization time‐of‐flight mass …

In a previous study, we isolated and characterized a new serotype k of Streptococcus
mutans from human blood and oral cavities. Analysis of the genes involved in biosynthesis …

Reliable distinction of Streptococcus pneumoniae and viridans group streptococci is
important because of the different pathogenic properties of these organisms. Differentiation …

We have identified an unusual group of viridans group streptococci that resemble
Streptococcus pneumoniae. DNA-DNA homology studies suggested that a subset of these …

The 16S–23S rDNA intergenic spacer regions (ISR) of different streptococcal species and
subspecies were amplified with primers derived from the highly conserved flanking regions …
