Group A Streptococcal Infection
The Group A β-hemolytic streptococcus (Streptococcus pyogenes, or GAS) is a form of β-hemolytic Streptococcus bacteria responsible for many common infections including "strep throat" and skin infections. There are many other types of Streptococcus including Group B Streptococcus and Streptococcus pneumoniae which cause other types of infections and should not be confused with Group A Strep. Several virulence factors contribute to the pathogenesis of GAS, such as M protein, hemolysins, and extracellular enzymes.
For more details on these virulence factors, see Streptococcus pyogenes.Read more about Group A Streptococcal Infection: Types of Infection, Severe Streptococcal Infections, Treatment, Relation With Tics and Obsessive Compulsive Disorder
Famous quotes containing the words group and/or infection:
“He hung out of the window a long while looking up and down the street. The world’s second metropolis. In the brick houses and the dingy lamplight and the voices of a group of boys kidding and quarreling on the steps of a house opposite, in the regular firm tread of a policeman, he felt a marching like soldiers, like a sidewheeler going up the Hudson under the Palisades, like an election parade, through long streets towards something tall white full of colonnades and stately. Metropolis.”
—John Dos Passos (1896–1970)
“This royal throne of kings, this sceptred isle,
This earth of majesty, this seat of Mars,
This other Eden, demi-paradise,
This fortress built by nature for herself
Against infection and the hand of war,
This happy breed of men, this little world,
This precious stone set in the silver sea,
Which serves it in the office of a wall,
Or as a moat defensive to a house
Against the envy of less happier lands;
This blessèd plot, this earth, this realm, this England.”
—William Shakespeare (1564–1616)
