The oral streptococcal group (mitis phylogenetic group) currently consists of nine recognized
species, although the group has been traditionally difficult to classify, with frequent changes …

The genus Streptococcus consists of Gram-positive, spherical or ovoid cells that are typically
arranged in chains or pairs. These cocci are facultatively anaerobic, non-sporing, catalase …
