1. Some bacteria, such as pathogenic Mycobacterium and Legionella pneumophilia prevent the acidification of the phagosome within phagocytes. Why might this protect these bacteria from being killed within the phagocyte?

2. Staphylococcus aureus and Streptococcus pyogenes both produce a toxin called leukocydin. How might this enable these bacteria to resist phagocytosis?
