A) polysaccharides on the cell wall
B) lipoteichoic acid
C) spiky M proteins
D) hyaluronic acid capsule
E) All of the choices are correct.

Accepted Answer

S. pyogenes, or Streptococcus pyogenes, utilizes a variety of virulence factors to establish infection and evade the host immune system. These include polysaccharides on the cell wall, lipoteichoic acid, spiky M proteins, and a hyaluronic acid capsule. Each of these components plays a role in adherence, invasion, or immune evasion, contributing to the bacterium's pathogenicity.
