Inhibition of phage infection by secondary metabolites produced by actinobacterial species
Members of the actinobacterial genus Streptomyces are prolific producers of natural products with a wide range of biological activities. However, a potential role in defense against viral infection has only been recognized recently.
This project will address the impact of phage infection on the antibiotic profiles of Streptomyces strains and their potential role in chemical defense strategies. Furthermore, we will specifically investigate the antiviral ‘mode of action’ of aminoglycoside antibiotics on defense against various phages.
Overall, experiments planned in the proposed project will provide important insights into the chemical defense of Streptomyces against phage infection and have the potential to discover new concepts in antiviral defense at the multicellular level.
