n1_4mer:GRV/n1_4mer:RV = (Global Relative Variance of OU patterns) / (Local Relative Variance of OU patterns)

n0_4mer:D = Distance between local and global OU patterns

n0_4mer:PS = Distance between 2 strands of same DNA molecule

Selected loci indicated by large D, increased GRV associated with decreased RV and moderate increase in PS




NC_004606: Streptococcus pyogenes SSI-1, complete genome

NCBI: NC_004606

Host Lineage: Streptococcus pyogenes; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria

General Information: This strain is a serotype M3 strain that was isolated from a toxic-shock patient in Japan and often associated with severe invasive infections, necrotizing fasciitis, and death. Causes tonsilitis. 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. This organism is a member of the normal human nasopharyngeal flora. Group A streptococcus and is the leading cause of uncomplicated bacterial pharyngitis and tonsillitis. This organism is commonly referred to by the lay press as "flesh eating bacteria".
