Query: NC_014498:62891 Streptococcus pneumoniae 670-6B chromosome, complete genome
Lineage: Streptococcus pneumoniae; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: This strain is a clinical isolate from the cerebrospinal fluid of a patient with meningitis in Italy in 2003. 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_007432:548964 Streptococcus agalactiae A909, complete genome
Lineage: Streptococcus agalactiae; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Causes meningitis and sepsis in newborns. 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 the leading cause of meningitis and sepsis in newborns. Additionally this organism is the cause of serious infections in immunocompromised adults. S. agalactiae is able to asymptomatically colonize human skin and mucous membranes. This organism is also implicated in cases of mastitis in cows.
