overview Our group is interested in how intracellular bacterial pathogens interact with and commandeer host cell functions during infection. We have studied the intracellular human pathogen, Legionella pneumophila for more than 30 years. This gram-negative species causes an acute febrile pneumonia called Legionnaires’ disease. People become infected with Legionella when they inhale contaminated aerosols. This can happen when cooling and ventilation systems, fountains, or whirlpools become contaminated. In these environments, Legionella replicates in single-celled amoebae. In human lungs these bacteria can infect and replicate in alveolar macrophages. In order to understand how Legionella is able to survive and grow inside amoebae and macrophages, we use genetic and genomic approaches to ask which functions in the bacteria and which ones in the host are important for infection. We found that Legionella has a “Type IV Secretion System” called the Icm/Dot System that translocates protein “effectors” to the host cell and that these effectors dramatically alter organelle trafficking in host cells as is shown in the accompanying diagram. The Legionella – containing vacuole, (LCV) is where the bacteria grow within cells in a nutrient-rich, protected niche.
