Infection Biology of Salmonella

During hot summer months, Salmonella frequently dominates the headlines with reports of infections caused by contaminated ice cream or egg dishes. The aggressive and quick bacteria rapidly infect a large number of people. However, our understanding of the mechanisms that Salmonella uses to infect us is fragmentary at best. In HZI’s Department of Molecular Infection Biology, the junior research group Infection Biology of Salmonella is studying the bacterium’s attack tactics – in order to use this information to develop new strategies in the ongoing fight against enteropathogenic bacteria.

Dr Marc Erhardt

Understanding the fundamental mechanisms used by Salmonella to get us sick will help us develop new strategies against all kinds of bacterial infections.

Marc Erhardt studied biology at the Universities of Ulm and Konstanz and performed his graduate work at the University of Utah, USA – with the help of a German National Academic Foundation grant. Erhardt stayed as a Boehringer Ingelheim Fonds fellow for his PhD research at the University of Utah and earned his PhD at the University of Konstanz in 2011. In 2010, he was the recipient of the DeLill Nasser Award of the Genetics Society of America. Upon his return to Europe, Erhardt became a post-doc and group leader at the Université de Fribourg, Switzerland, where he was the recipient of an EMBO Long-Term Fellowship, a Marie Curie International Incoming Fellowship, and the Elisabeth Gateff Award of the German Genetics Society. Starting in 2013, Marc Erhardt will be assuming his new role as head of HZI’s Infection Biology of Salmonella Helmholtz Young Investigator group.

  • Gefährliche Spritzen – Salmonellen infizieren uns mit molekularen Nadeln
    Salmonellen leben und töten überall auf der Welt. Mehrere Hundert Millionen Kranke gehen jährlich weltweit auf ihr Konto.Die Strategien mit denen sie sich unseren Behandlungsversuchen entziehen, werden immer raffinierter, die Resistenzen gegen Antibiotika immer mehr. Marc Erhardt geht auf der Suche nach neuen Therapieansätzen einen ungewöhnlichen Weg: Er untersucht das Spritzbesteck, mit dem Salmonellen uns infizieren und er sucht nach Ansätzen, die die Bakterien nicht töten – und damit Resistenzen provozieren –, sondern nur ihre Spritze verstopfen. Begleiten Sie Marc Erhardt in sein Labor…
