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 …

Streptococci of serological groups N and D were found to belong to three different 23S
ribosomal RNA (rRNA) homology clusters which are not closely related to each other. One …

We determined the 16S rRNA sequences of the type strains of Streptococcus mitis and
Streptococcus gordonii and calculated the phylogenetic distances between those organisms …

The 16S-23S rRNA intergenic spacer has been suggested as a suitable region of the
bacterial genome from which to derive useful taxonomic information, particularly with regard …

Partial sequences of the recN gene (1249 bp), which encodes a recombination and repair
protein, were analysed to determine the phylogenetic relationship and identification of …

Streptococcus pyogenes, S. equinus, S. bovis, S. salivarius, S. sanguis, S. mutans, S. rattus,
S. cricetus, S. lactis, S. raffinolactis and Enterococcus faecalis have been characterized by …

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

Summary DNA-rRNA and DNA-DNA hybridization studies indicate that the classical
pyogenic streptococci can be divided into five homology clusters. Based on these studies …

The rnpB gene is universally present in bacterial species and encodes the RNA subunit of
endoribonuclease P. In this study, rnpB was sequenced in 50 type strains and 29 additional …

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 …
