Lineage: Staphylococcus aureus; Staphylococcus; Staphylococcaceae; Bacillales; Firmicutes; Bacteria

General Information: This strain is a common strain associated with mastitis in cattle. This organism is responsible for several hundred million dollars worth of annual economic loss to animal production each year. Staphylcocci are generally found inhabiting the skin and mucous membranes of mammals and birds. Some members of this genus can be found as human commensals and these are generally believed to have the greatest pathogenic potential in opportunistic infections. This organism is a major cause of nosocomial (hospital-acquired) and community-acquired infections. S. aureus continues to be a major cause of mortality and is responsible for a variety of infections including, boils, furuncles, styes, impetigo and other superficial skin infections in humans. Also known to cause more serious infections particularly in the chronically ill or immunocompromised. The ability to cause invasive disease is associated with persistance in the nasal cavity of a host.

Subject: NC_007297:1379742 Streptococcus pyogenes MGAS5005, complete genome

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

General Information: Isolated from an invasive case in Ontario. 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. S. pyogenes is a 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".
