NC_010582:1771591 Streptococcus pneumoniae CGSP14, complete genome
Host Lineage: Streptococcus pneumoniae; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: 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. 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. This organism is a member of the normal human nasopharyngeal flora. This organism is also the most common cause of sinusitis, acute bacterial otitis media, and conjunctivitis beyond early childhood.
