Bacterial adaption mechanism

Friday 29 January 2016

Bacterial adaptation mechanism

Metabolic activity is essential in all living organisms to generate energy for cellular biosynthesis. Unlike plant and animal cells, most bacteria are exposed to a constantly changing physical and chemical environment. In order to survive or to cause disease bacterial communities must be able to adapt their metabolism in response to changes in the environmental conditions. This project aims to discover environmental signals and molecular adaptation mechanisms that enable the survival and virulence of intestinal bacteria. The work involves the use of a combination of molecular biology, biochemistry, microbiological and tissue culture techniques and is carried out in an international setting. Results increase understanding of host pathogen interactions and are important to develop novel therapeutic, prevention and diagnostic strategies.
