The group has a strong interest in the events that lead to persister cell formation in the model bacterium Escherichia coli. Persisters are transiently multidrug-tolerant cells that have entered a dormant state and thereby escape antibiotic treatments. As soon as they resuscitate from dormancy, they are fully susceptible to antibiotics again. We aim to unravel the physiological state of persister cells and the mechanisms leading to persistence. We apply microbiological, genetic, and biochemical tools, and use high-throughput techniques for investigation of bacterial transcriptomes and proteomes. Learn more...
