Abstract

In the face of multi-resistant pathogens it is time to find new antibacterial strategies. A system-based approach to studying antibiotic action of natural compounds, antimicrobial peptides, and small molecules allows investigation of clinically unexploited antibiotic classes and targets as well as intrinsic bacterial defence mechanisms. We also investigate the antibacterial activity and mechanisms of action of technical plasmas (ionized gases). They are promising wound disinfectants, which are in clinical development to complement established antibiotic approaches.
