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.
- Störfunk im Mund - Ein neuer Weg gegen Plaque
Pelz auf den Zähnen ist nicht nur unangenehm, sondern vor allem der Auslöser für Karies. Das einzige Mittel gegen den Bakterienangriff: Zahne putzen. Weshalb nach jeder neuen Nacht wieder Millionen Bakterien unsere Zähne besiedeln und was wir in Zukunft dagegen tun können, erklärt Ihnen Irene Wagner-Döbler. Und legen Sie die Zahnbürste schon einmal bereit...
