Query: NC_012466:318675 Streptococcus pneumoniae JJA, complete genome
Lineage: Streptococcus pneumoniae; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This organism is a member of the normal human nasopharyngeal flora. There are more than 85 different antigenic types of S. pneumoniae, which are classified based on their capsule antigens. This organism is also the most common cause of sinusitis, acute bacterial otitis media, and conjunctivitis beyond early childhood. S. pneumoniae is also known to cause pneumonia, meningitis, and bacteremia. Streptococci are Gram-positive, non-motile, non-spore forming, 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_011134:1951682 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.
