Query: NC_004606:623853 Streptococcus pyogenes SSI-1, complete genome

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".

Subject: NC_002662:1042546 Lactococcus lactis subsp. lactis Il1403, complete genome

Lineage: Lactococcus lactis; Lactococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria

General Information: This strain is used widely in laboratory research and is a plasmid-free derivative of strain IL594 isolated from a cheese starter culture. Microorganism used in cheese production. This microbe is a member of the lactic acid bacteria and produces lactic acid from sugars. It is found in many environments including plant and animal habitats. Lactococcus lactis is used as a starter culture for the production of cheese products (such as cheddar) and in milk fermentations and, as such, is one of the most important microbes in the food industry. The degradation of casein, acidification by lactic acid, and production of flavor compounds, processes that are caused by the bacteria, contribute to the final product.
