Infection by the ulcer-causing bacterium Helicobacter pylori
Bacterial chemotaxis


How pathogenic bacteria such as Helicobacter pylori use environmental cues to establish infection.

For pathogenic bacteria to set up an infection, they must know that they have arrived at the proper location. Karen Ottemann's laboratory investigates how bacteria translate chemical and physical cues in their host environment into an advantageous response.

Ottemann lab members are particularly interested in how pathogens use swimming during infection, using the bacterium Helicobacter pylori as a model for this ability. This pathogen infects some 3 billion people and can lead to serious disease, including ulcers and cancer. Bacteria do not swim at random, but instead direct their motility (chemotaxis) by the activity of sensing proteins called chemoreceptors. The chemotaxis system thus allows us to examine the types of cues sensed by pathogens.
