Mycobacterium tuberculosis (Mtb) is a bacterial pathogen that can cause skin infections as well as pneumonia. Mtb is often phagocytosed by immune cells called macrophages that normally destroy bacterial pathogens, but Mtb is somehow able to prevent the maturation of phagosomes into phagolysosomes, and to live and replicate inside these organelles. Which of the following differences would you expect contribute to the survival of a bacterium within an Mtb-containing phagosome, compared to a phagolysosome? (select two answers)
