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 a, group and/or infection:
“The conflict between the need to belong to a group and the need to be seen as unique and individual is the dominant struggle of adolescence.”
—Jeanne Elium (20th century)
“Instead of seeing society as a collection of clearly defined “interest groups,” society must be reconceptualized as a complex network of groups of interacting individuals whose membership and communication patterns are seldom confined to one such group alone.”
—Diana Crane (b. 1933)
“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)
