Abstract:
Predation by protozoa provides a strong selective pressure for Legionella to develop and maintain mechanisms conferring resistance to digestion and ability to replicate within both amoebae and mammalian macrophages. Here we describe how to isolate environmental protozoa that prey on virulent Legionella. These protists are extremely useful models to study the cellular mechanisms employed by Legionellae to survive and grow in its natural environment. We present here procedures that are available to study the interactions between environmental protozoa and Legionella and thus increase our current understanding of Legionella virulence and the infection process.
