Different strains of Streptococcus pyogenes have different virulence factors, giving these microbes much versatility. Virulence factors include which of the following? Choose one or more:
A.A capsule that, when thick, will help the organism avoid phagocytosis by macrophages
B.A cell wall containing lipoteichoic acid, thought to facilitate adherence to pharyngeal epithelial cells
C.Enzymes that lyse blood cells (streptolysins)
D.The production of several endotoxins called streptococcal pyogenic endotoxins (SPEs)
Antiphagocytic factors produced by microorganisms include all of the following EXCEPT
a. leukocidins which are enzymes that destroy white blood cells
b. capsules
c. exotoxins
d. endotoxins
e. fimbriae
Which virulence factor description among A-E is false?

A) O Adhesins: fimbriae or pili are examples of this
B) O Invasins: virulence factor of intracellular pathogens
C) O Kinases: breaks apart a blood clot; streptokinase is an example.
D) O Hyaluronidases: dissolves connections between cells of a tissue
E) O Coagulases: found in certain Staphylococcus pathogens;
induces clot formation in the body
F) O None of A-E is false; all are true
