The Ottemann Research Group studies how the bacterium Helicobacter pylori uses environmental cues to target the stomachs of its host. H. pylori infects some 3 billion people around the globe--approximately half the world's population. In the majority of cases, the bacterium establishes chronic infections. Around 5-10% of those who are infected develop some form of serious illness, such as ulcer disease or gastric cancer.

H. pylori is particularly well-suited to these studies because it has a relatively simple molecular system for sensing its environment. Aided by funding from NIH, Ellison Medical Foundation and University of California Cancer Research Coordinating Committee, we can thus examine how bacteria translate host chemical and physical signals into a response that allows them to colonize a mammalian host.

Current Research Topics in our lab include:

  • What chemoreceptors does H. pylori use during infection, and what ligands or physical parameters do these receptors sense?
  • How is ligand-binding information relayed from the chemoreceptors to control the swimming behavior of H. pylori?
  • When does H. pylori swim during infection, and how does swimming promote a robust infection state?
  • Can we develop non-invasive ways to detect H. pylori within hosts?
  • What other bacterial gene products are needed for full infection by this microbe?
  • What types of ligands do chemoreceptors sense?
