Abstract
Legionella are gram-negative bacteria ubiquitously found in freshwater and soil environments. Once inhaled by humans, Legionella infection could result in a severe form of pneumonia known as Legionellosis. Legionella translocate ~300 effector proteins into host cells via the Dot/Icm type IV secretion system, which is central to Legionella pathogenesis. Here I describe a brief review on recent advances in research on the molecular basis of Legionella—eukaryotic-cell interaction.
