NC_007432:654904 Streptococcus agalactiae A909, complete genome
Host 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.
