Understanding Virulence Of Invasive Staphylococcus Aureus

Funding Amount
$772,711.00
Summary
Staph aureus (Golden staph) is a major cause of disease in humans. In this project we will use state-of-the-art molecular biology and genomics to fully understand the mechanisms of virulence in this pathogen. This information will inform future approaches to development of therapeutics, as well as the use of genomics in clinical microbiology and disease management.
CAMERA: Combination Antibiotic Treatment For Methicillin Resistant Staphylococcus Aureus Bacteraemia - A Randomised Controlled Trial

$1,162,248.00
Summary
MRSA (golden staph) is resistant to the most useful class of antibiotics: beta-lactams. It is more difficult to treat than antibiotic-sensitive strains. Standard treatment for MRSA is vancomycin but it has high failure rates. Although MRSA is resistant to beta-lactams, lab studies show that they enhance vancomycin’s bacterial killing when used together. CAMERA2 is an RCT comparing vancomycin alone to combination therapy (vancomycin plus flucloxacillin) for adults with MRSA blood stream infection
Genomics Dissection And Prevention Of Bacterial Transmission Events

Funding Amount
$891,290.00
Summary
This project aims at improving public health capacity to limit the spread of infectious diseases in hospital and community settings. The multi-disciplinary team of investigators will link epidemiological data with the finest resolution data from bacterial genomes in order to pinpoint events of infection transmission between individuals. Two high-burden pathogens (golden staph and food-borne Salmonella) will be used as exemplars of infectious diseases with different biology and modes of spread.
Understanding The Contribution Of SRNAs To Antibiotic Resistance In Staphylococcus Aureus

Summary
Golden Staph is a major problem in Australian hospitals. This project will use cutting edge technology to investigate how Golden Staph responds to and resists antibiotics used to treat human infections, leading to new strategies for the prevention and treatment of antibiotic resistant bacteria.
The Inhibition Of Biotin Protein Ligase As A New Source Of Antibiotics

Summary
We have become so accustomed to treating bacterial infections with antibiotics that it is hard to imagine life without them. However, the emergence of drug-resistance is creating a global health care crisis. Recently, there has not been enough attention paid to replacing old antibiotics with new products to combat drug resistance. Our team is addressing this challenge. We have discovered a new class of antibiotic that is unlike any other drug in clinical use.
Mechanisms Of Alpha-hemolysin Induced Immunoevasion By Staphylococcus Aureus

Funding Amount
$465,475.00
Summary
S. aureus infections represent a serious global health problem. Currently, no vaccination is available demanding a better understanding of the immune response against this bacterium. We will test the hypothesis that S. aureus alpha-hemolysin represses the migration of innate immune cells to sites of cutaneous infection resulting in diminished immunity. Unraveling the mechanism behind this phenomenon will pave the way to better prophylactic and therapeutic measures against S. aureus infections.
Pathogenic Consequences And Mechanistic Insights Of Daptomycin Resistance In Staphylococcus Aureus

Funding Amount
$540,633.00
Summary
Staphylococcus aureus is one of the most common human bacterial pathogens. This project aims to characterise the mechanisms that Staph uses to develop resistance to one of our last-line antibiotics, and will determine the effects of this resistance on the ability of the bacteria to cause human disease.
Antibiotic Tolerance And Small RNA Networks In Staphylococcus Aureus
Funder
National Health and Medical Research Council
Funding Amount
$521,559.00
Summary
Treatment of MRSA is restricted to last line antibiotics and treatment failure is associated with an intermediate tolerance to vancomycin. Regulatory molecules termed small RNA mediate responses to antibiotic challenge but their functions are poorly understood. This proposal will profile sRNA function to understand how they adapt S. aureus to antibiotic challenge. A molecular understanding of vancomycin-tolerance will inform development of diagnostics and treatment strategies.
Essential Gene Regulation In Multi-drug Resistant Golden Staph: A New Path Towards Control

Funding Amount
$784,452.00
Summary
New antibiotics effective against Golden Staph are urgently needed. This project will investigate a new approach to weaken Golden Staph defences with the potential to make existing antibiotics more effective at killing these bacteria.
Forensic Approach For Reservoir Identification For Serious S. Aureus Infections In Top End Dialysis Clients

Summary
Indigenous Australians suffer from kidney disease at a much higher rate than non-Indigenous Australians and are far more likely to require dialysis treatment. Infections with the bacteria Staphylococcus aureus (Golden Staph) further reduce the quality of life for these patients, causing serious disease and even death. We aim to identify exactly where these Golden Staph infections are coming from so that we can design targeted procedures to reduce the chance of infections occurring.
