Eradicating bacterial biofilms with nitroxide-antimicrobial hybrids. This project aims to develop new antimicrobials to address the rise of drug-resistant infections and resilient bacterial communities called biofilms. We aim to break new ground in our fundamental knowledge of antimicrobial mechanisms and exploit this understanding by fusing cellular/molecular microbiology and synthetic chemistry approaches. We seek to gain an in-depth understanding of how nitroxides induce bacterial biofilm dis ....Eradicating bacterial biofilms with nitroxide-antimicrobial hybrids. This project aims to develop new antimicrobials to address the rise of drug-resistant infections and resilient bacterial communities called biofilms. We aim to break new ground in our fundamental knowledge of antimicrobial mechanisms and exploit this understanding by fusing cellular/molecular microbiology and synthetic chemistry approaches. We seek to gain an in-depth understanding of how nitroxides induce bacterial biofilm dispersal, which is critical for the discovery of anti-biofilm molecules that do not fail due to resistance development. These breakthroughs should induce a step-change in our ability to reduce the occurrence of biofilm-related infection in fields ranging from medical and veterinary to biotechnology and agriculture.Read moreRead less
Manipulation of mitochondrial function by Legionella pneumophila. . The intracellular bacterial pathogen Legionella pneumophila co-evolved with eukaryotic hosts and has developed sophisticated mechanisms to manipulate human cell function – mitochondria in particular – by secreting >300 effector proteins through a specialised Type-IV system into the host cell. This research aims to understand the function of effector proteins targeted to mitochondria; delivering important new knowledge in host-pa ....Manipulation of mitochondrial function by Legionella pneumophila. . The intracellular bacterial pathogen Legionella pneumophila co-evolved with eukaryotic hosts and has developed sophisticated mechanisms to manipulate human cell function – mitochondria in particular – by secreting >300 effector proteins through a specialised Type-IV system into the host cell. This research aims to understand the function of effector proteins targeted to mitochondria; delivering important new knowledge in host-pathogen and mitochondrial biology and advanced cell biology tools. With most of the effector proteins yet to be characterised, benefits from the project will be to reveal specifically how these target mitochondria, and more broadly, how bacterial pathogens manipulate organelles for their survival.Read moreRead less
Antibacterial Material Design via Mechanism-Based Mathematical Modelling. This Project aims to provide new rules for the design of novel polymer materials with antibacterial properties by employing mechanism-based mathematical modelling.
This Project expects to generate new understanding of those mechanisms which underpin the antibacterial activity of these materials, how bacteria respond to these through metabolic changes and emergence of resistance.These rules will govern material design to yi ....Antibacterial Material Design via Mechanism-Based Mathematical Modelling. This Project aims to provide new rules for the design of novel polymer materials with antibacterial properties by employing mechanism-based mathematical modelling.
This Project expects to generate new understanding of those mechanisms which underpin the antibacterial activity of these materials, how bacteria respond to these through metabolic changes and emergence of resistance.These rules will govern material design to yield new antibacterial materials with improved properties.
Expected outcomes of this project may be a novel mechanism-based mathematical model that will enable the next-generation of antibacterial materials.
This outcome will help address the increasing economic and social burden of antibiotic drug resistance in Australia.
