New antibiotics from old bacteria

Summary This project will investigate the antibacterial activity of a diverse collection of 700 human pathogenic Actinobacteria held by our state microbiology reference laboratory, with the ultimate aim to identify new antimicrobials that can inhibit hospital superbugs, such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci. A combination of techniques will be used in this project, including genomics, molecular biology, biochemistry and mass spectrometry, to identify new antibiotics produced by this collection of bacteria.

Project Details

Development of new antibiotics is key to addressing the crisis in human health caused by the rise of multidrug resistant superbugs. Traditionally, soil-derived Actinobacteria, particularly the genus Streptomyces, are the most prolific antibiotic producers, however, high re-discovery rates of known compounds demand the testing of new reservoirs of biodiversity and bioactive molecules. Human-associated bacteria, including pathogenic bacteria, are a previously untapped source of antimicrobial diversity. This project will investigate the antibacterial activity of a diverse collection of 700 human pathogenic Actinobacteria held by our state microbiology reference laboratory, with the ultimate aim to identify new antimicrobials that can inhibit hospital superbugs, such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci. A combination of techniques will be used in this project, including genomics, molecular biology, biochemistry and mass spectrometry, to identify new antibiotics produced by this collection of bacteria. Students will develop a broad range of skills in each of these areas and will use these to increase the antimicrobial drug discovery pipeline.
