How does Listeria reproduce?

After entering a host cell, L. monocytogenes rapidly escape from phagosomes through the combined actions of a pore-forming hemolysin, listeriolysin O, and two phospholipases, PlcA and PlcB, and then replicates in the cytosol (O'Riordan & Portnoy, 2002; Schnupf & Portnoy, 2007).
