Molecular mimicry and original biochemical strategies for the biogenesis of a Legionella pneumophila replicative niche in phagocytic cells.

Legionella pneumophila is a paradigm of highly adapted intravacuolar pathogens that acquired the rare ability to replicate within a phagocytic cell. Here, we review recent progress about the role of Type 4 secretion system effectors involved in the biogenesis of the replicative niche, the Legionella containing vacuole.
