TABLE 4.
Phylogenetic clusters observed with tuf and 16S rRNA genes within phenotypic streptococcal species groups
 |
a
Phylogenetic clusters with 16S rDNA were devised based on trees constructed with sequences available in public databases. Ambiguities and gaps were excluded for phylogenetic analysis.
b
Species in bold type branched differently based on tuf phylogeny compared to 16S rDNA phylogeny.
c
Different strains from this species branched with different clusters.
d
These species have not been assigned to a phenotypic streptococcal species group.
