How Do Some Pathogens Prevent Complement Activation or Avoid the Effects

question 52

Multiple Choice

How do some pathogens prevent complement activation or avoid the effects of activated complement?

• A) Some pathogens produce C5a peptidase that destroys complement C5a, a chemoattractant that recruits phagocytes to the area of infection.
• B) Some pathogens hijack the host's regulatory membrane proteins that inactivate C3b, preventing the triggering of the alternative activation pathway.
• C) Some pathogens produce C5a peptidase that causes destruction of phagoctyes recruited to the area of infection.
• D) Some pathogens hijack the host's regulatory membrane proteins that inactivate C3b, preventing the triggering of the alternative activation pathway AND some pathogens produce C5a peptidase that destroys complement C5a, a chemoattractant that recruits phagocytes to the area of infection.
• E) Some pathogens hijack the host's regulatory membrane proteins that inactivate C3b, preventing the triggering of the alternative activation pathway AND some pathogens produce C5a peptidase that causes destruction of phagoctyes recruited to the area of infection.
