Microbial Communication

If when you wake up in the morning your teeth feel sticky, this indicates bacteria that live in your mouth have formed a slimy structure called a biofilm. To do this, they engage in a very special form of communication using chemical signals. Furthermore, bacteria in the ocean communicate with one another as well as with the tiny planktonic algae which provide about half of the world´s primary production to the global carbon cycle. Our scientists are deciphering these processes in order to be able to influence them, for instance to prevent caries.


Prof Dr Irene Wagner-Döbler

We want to understand the mechanisms behind the bacterial communication in detail. Then we can disturb the conversations and prevent that the bacteria develop their pathogenic properties.

Irene Wagner-Döbler studied in Munich where her PhD research was devoted to an ecological topic – The Vertical Migration of Planktonic Insect Larvae in lakes. She then joined the GBF Braunschweig (the forerunner of the HZI) as assistant to the Scientific Director, and entered the Department for Microbiology in 1989 where she has worked on issues in microbial ecology. In 2001 Irene Wagner-Döbler became a professor at the Technical University of Braunschweig and has led the working group “Microbial Communication” since 2004. She has been honoured with several international research awards.
