 Streptococcus pyogenes
Streptococcus pyogenes (Group A streptococcus) is a Gram-positive, nonmotile, nonsporeforming coccus that occurs in chains or in pairs of cells.
Acute Streptococcus pyogenes infections may present as pharyngitis (strep throat), scarlet fever (rash), impetigo (infection of the superficial layers of the skin) or cellulitis (infection of the deep layers of the skin).
Streptococcus pyogenes owes its major success as a pathogen to its ability to colonize and rapidly multiply and spread in its host while evading phagocytosis and confusing the immune system.

 Diagnostic test for Streptococcus A - Patent 4618576
The presence of Group A Streptococcus in a biological specimen is determined from the presence of Streptococcus A antigen.
The mechanism of antigen release is unknown; however, it is believed that the enzymes release that portion of the Streptococcus A antigen molecule containing the antibody-reactive determinant(s) from that portion of the molecule that tends to cling to the swab fibers.
The sensitivity of the Group A Streptococcus latex agglutination test was determined from 309 pharyngeal swab specimens which were determined to be positive by culture for beta-hemolytic streptococci and confirmed as Group A by the capillary precipitin test.

Background: Streptococcus bovis is the main human pathogen among nonenterococcal group D streptococci.
Streptococcus pneumoniae was by far the most frequent isolate in that study.
Mortality was related to the virulence of S bovis and to a more frequent occurrence of underlying extracardiac disease from which patients died during follow-up care.

As is the case with other strains of group A Streptococcus, those that cause necrotizing fasciitis are treated with common antibiotics, although not necessarily the same ones used to treat milder diseases.
Group A Streptococcus bacteria are known to be sensitive to penicillin, so it is the preferred antibiotic for most types of streptococcal infections.
