Our laboratory (sites.fct.unl.pt/infection-biology) aims to understand the molecular and cellular mechanisms by which bacterial pathogens modify the normal functioning of animal host cells. This fundamental knowledge might then be used to develop specific strategies to combat infectious diseases. Because microbial pathogens are the ultimate cell biologists - as they co-evolved with their eukaryotic hosts for millions of years -, we also seek to understand basic eukaryotic cell biology. We focus on the human pathogen Chlamydia trachomatis, which are obligate intracellular bacteria that cause sexually transmitted diseases and ocular infections (trachoma), and on Legionella pneumophila and Salmonella enterica, which are both facultative intracellular bacteria that cause pneumonia (Legionnaire's Disease) and gastrointestinal and systemic diseases (typhoid fever) in humans, respectively.
