Architecture of the vir regulons of group A streptococci parallels opacity factor phenotype and M protein class.

Journal of bacteriology - 1 Aug 1992

Haanes E J, Heath D G, Cleary P P

Abstract excerpt

Group A streptococci have traditionally been categorized into two broad groups based on the presence or absence of serum opacity factor (OF). Recent studies show that these two groups vary in a number of properties in addition to the OF phenotype, including sequence variations in the constant region of the antiphagocytic M protein genes, the presence or absence of immunoglobulin G Fc receptor proteins, and the...
