Query: NC_015760:343874 Streptococcus salivarius CCHSS3, complete genome
Lineage: Streptococcus salivarius; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: The commensal bacterium Streptococcus salivarius is predominant specie of the human oropharyngeal tract and exerts an important role in oral ecology. Streptococcus salivarius is an aerobic, gram-positive coccus. This organism is the most common organism isolated from the human oral cavity. Streptococcus salivarius can also be an opportunistic pathogen causing endocarditis, blood infection, and peritonitis. 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.
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.
