Abstract
dc.description.abstract
Alternative phylogenies for the genus Streptococcus
have been proposed due to uncertainty about the among-species group
relationships. Here, we performed a phylogenetic analysis of the genus
Streptococcus, considering all the species groups and also the genomic
data accumulated by other studies. Seventy-five species were subjected
to a Bayesian phylogenetic analysis using sequences from eight genes
(16S rRNA, rpoB, sodA, tuf, rnpB, gyrB, dnaJ, and recN). On the basis
of our results, we propose a new Phylogeny for the genus, with special
emphasis on the inter-species group level. This new phylogeny differs
from those suggested previously. From topological and evolutionary
distance criteria, we propose that gordonii, pluranimalium, and
sobrinus should be considered as new species groups, in addition to
the currently recognized groups of mutans, bovis, pyogenic, suis, mitis,
and salivarius
