Gro ¨schel et al. describe the virulenceneutral expression of the ESX-1 type VII secretion system of Mycobacterium marinum in the attenuated BCG vaccine. ESX-1-marinum enables recombinant BCG to rupture the phagosome and to induce cytosolic pattern recognition and dedicated innate immune signaling in mice, resulting in increased protection against tuberculosis.
