(3) Some species of GCS, chiefly SDSE, have many virulence factors found in GAS like M protein, streptokinase, and streptolysins, but there are some that are missing like cysteine protease.
(2010) Specific behavior of intracellular Streptococcus pyogenes that has undergone autophagic degradation is associated with bacterial streptolysin O and host small G proteins Rab5 and Rab7.
The cells were incubated at 37[degrees]C for 2 min and subsequently, 4.6[micro]L of streptolysin O (Sigma) at a final concentration of 230 ng/mL was added and incubated at 37[degrees]C for 50 min.

A two-component regulatory system, CsrR-CsrS, represses expression of three Streptococcus pyogenes virulence factors, hyaluronic acid capsule, streptolysin S and pyrogenic exotoxin B.
Insertional inactivation of streptolysin S expression is associated with altered riboflavin metabolism in Streptococcus pyogenes.
* Streptolysin, which repels and damages phagocytes;
Louis, MO) to enter the cells, a stock solution of 100 [micro]g/ml of dihydrocytochalasin B (dihydroCB) in PBS containing 0.01 units/ml streptolysin O (Sigma) was prepared.
The effect of Streptolysin on the process of wound healing was studied.
Similar to GAS, GGS shares multiple virulence factors, including streptokinase, fibronectin, IgG binding proteins, streptolysin O, C5a peptidase (reference 18 in online Technical Appendix), and antiphagocytic M proteins, of which emm types stg10 and stg2078 of GGS are significantly associated with invasive disease (reference 19 in online Technical Appendix).
