Our project is placed into The Collaborative Research Centre (CRC) 973 “Priming and Memory of Organismic Responses to Stress“ (http://www.sfb973.de/). Our project will elucidate how the sequential exposure to antimicrobials impacts on stress responses and fitness of the model bacterium Escherichia coli. We will use a suite of antimicrobial peptides and synthetic antibiotics and relate this to our understanding of immune effectors in a model insect during a persistent infection. We will then investigate how priming by the first stressor leads to an altered response against a second stressor studying growth rate in vitro and virulence in an insect model as performance indicators. By RNA-seq, including mRNAs and small-RNAs, we will try to determined the molecular basis of the altered response during priming events in bacteria.
