Salmonella • typhoid • complex disease • animal model • mutagenesis

Research Interests

My research focuses on identifying and characterizing genes involved in the host immune response to pathogenic Salmonella using mouse models of the disease. Salmonella are ubiquitous, facultative intracellular Gram-negative bacteria causing human diseases (typhoid fever and salmonellosis) of increasingly important public health concern both in developed and developing countries. Salmonella Typhi is the causative agent of typhoid fever and Salmonella Typhimurium and Enteritidis are associated with frequent outbreaks of food-borne gastroenteritis (salmonellosis). Multidrug resistant non-typhoidal Salmonella (NTS) infections are also increasingly frequent in developing countries. My lab is using different models of infection (systemic, chronic carriage and intestinal infection) and genetic approaches (positional cloning of Mendelian and complex phenotypes and chemical mutagenesis) to study the complex mechanisms underlying the host response to Salmonella infection.
