Questions and Answers

Which of the following mechanisms do mycobacteria use to resist destruction inside phagocytes?

  • Resistance to the actions of complement proteins due to their cell walls
  • Inhibition of fusion of phagosomes containing bacteria with lysosomes due to a lipid in their cell walls (correct)
  • Production of a protein that enables it to escape from phagocytic vesicles
  • Production of ROS and NO that are not susceptible to phagolysosomes
