Salmonella Typhoid Toxin: Biology, Pathogenesis & Neutralization
Typhoid fever – caused by Salmonella enterica serovar Typhi (S. Typhi) adapted to solely to humans – is one of the most successful infectious diseases in human history, and remains a major global health threat with continuing outbreaks occurring in many developing countries. Using this exemplary bacterial pathogen that causes a serious real-world problem that kills 0.2 million and sickens 21 million people every year, my research team seeks answers to fundamental biological questions, such as
(1) what makes S. Typhi so pathological? and
(2) despite an extremely narrow host range (human-specific), what makes S. Typhi so successful?
We use a multidisciplinary approach to define in molecular (when possible atomic terms), cellular, and organismal level the functional interface between this important human bacterial pathogen and the host. We hope our research offers rational avenues to the development of more effective ways of treating and preventing typhoid fever and also provides critical insights into the pathogenesis of human-specific pathogens.
Our ongoing research is supported, in part, by National Institutes of Health, USDA National Institute of Food and Agriculture, and the Mizutani Foundation for Glycoscience.
We are recruiting strongly motivated personnel (postdoc, graduate students, undergraduate students) with research interests in the interplay between bacterial pathogens and hosts. Please contact Jeongmin (js2957 at cornell.edu) with your CV, if you are highly motivated and interested in understanding molecular mechanisms of infectious diseases. Prospective graduate students need to consult the graduate admission program at Cornell University for the current application procedures (e.g. Graduate Programs in Biological and Biomedical Sciences, Microbiology, or Biochemistry, Molecular and Cell Biology).
