Query: NC_013928:9494 Streptococcus mutans NN2025, complete genome
Lineage: Streptococcus mutans; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This strain is a clinical serotype c strain isolated in Japan in 2002. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes. Streptococcus mutans was first isolated in 1924 from human carious (cavities) lesions and is the main cause of tooth decay. This organism thrives in a bacterial community known as a dental plaque which forms on the surface of teeth. This organism has also been implicated in cases of infective endocarditis.
Subject: NC_011134:1854868 Streptococcus equi subsp. zooepidemicus str. MGCS10565, complete
Lineage: Streptococcus equi; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Streptococcus equi subsp. zooepidemicus str. MGCS10565 was responsible for a large and severe epidemic outbreak of poststreptococcal glomerulonephritis. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. Streptococcus equi is comprised of three subspecies equi, zooepidemicus and ruminatorum all of which cause disease in horses, sheep or goats. Streptococcus equi subsp. zooepidemicus has also been isolated from clinical cases in humans and other animals. This species is a Lancefield C group bacterium.
