‘Intelligent’ Antibacterial Coatings For Improving Outcomes With Infections Associated With Dialysis Catheters
Funder

Funding Amount
$653,806.00
Summary
The outcomes of this projects will set the framework for the rational design of novel and ’intelligent‘ antibacterial coating that selectively respond to the ‘virulent’ bacteria that cause such significant and recurrent issues in routine kidney dialysis regimens and will underpin future academic and commercial collaborative efforts to rationally-design and manufacture kidney dialysis catheters with substrate surface characteristics that will enhance utility, function and clinical application;
Dissecting The Molecular Basis For Emerging Alcohol Tolerance In VRE
Funder
National Health and Medical Research Council
Funding Amount
$836,620.00
Summary
Infections caused by vancomycin resistant Enterococcus faecium (VREfm) are a major and growing problem in health care facilities around Australia. We have observed that VREfm is becoming significantly more resistant to killing by alcohol, probably due the increasing use of alcohol-based hand wash products. This project will identify how VREfm is becoming alcohol tolerant, knowledge that will be used to develop alternative disinfection methods or other intervention strategies to stop its spread.
Anti-sporulation Strategies For Clostridium Difficile Infections

National Health and Medical Research Council
Funding Amount
$651,559.00
Summary
Hospital-acquired infections with the bacterium Clostridium difficile are a major global public health concern with highly virulent isolates emerging overseas in 2002 and in Australia in 2010. These strains have spread through our hospitals and are also found in the community. This project will increase our understanding of how these strains spread and will provide knowledge that is critical for developing improved strategies for preventing these infections.
Defining A Role For TLR7/8 In Helicobacter Pylori Infection
Funder
National Health and Medical Research Council
Funding Amount
$568,007.00
Summary
Helicobacter pylori is a bacterium responsible for chronic gastritis and is associated with development of gastric cancer. In this project, we will investigate how the immune system interacts with H. pylori during colonisation – focusing on a sensor of the immune system, called TLR8 (and its mouse equivalent, TLR7).
Strengthening Frontline Clinicians’ Infection Control: A Multi-method Study To Reduce MRSA Infection And Transmission
Funder
National Health and Medical Research Council
Funding Amount
$800,339.00
Summary
Despite handwashing initiatives and the introduction of alcohol gels, cross-infection in hospitals remains a terrible risk for patients and creates a huge cost for health care funders. This study deploys a video-based technique called video reflexivity to alert frontline clinicians to the infection risks that are inherent in their every practice, educating them to become smarter about such risk.
Population Genomics Of Plasmodium Vivax In Papua New Guinea

Funding Amount
$597,238.00
Summary
Plasmodium vivax malaria is a serious global public health problem that has not received the attention it deserves, despite having serious clinical implications and presenting a major problem for regional malaria control programmes. In a study of people living in a malarious area of PNG, we aim to investigate the diversity of natural parasite populations, to better understand the possible effects of malaria control interventions on transmission and human immunity.
Function And Molecular Mechanism Of Histidine-rich Glycoprotein In Necrotic Cell And Pathogen Clearance
Funder
National Health and Medical Research Council
Funding Amount
$525,957.00
Summary
This research proposal is to investigate the molecular mechanism and function of a blood serum protein, histidine-rich glycoprotein (HRG), in protecting against tissue injury caused by inflammation and infection. HRG has been implicated in controlling important aspects of tissue injury by aiding removal of dead cells and pathogens. Understanding the role of HRG in these disease settings may allow the development of approaches for the treatment of inflammatory, autoimmune and infectious disease.
Regulation Of Metabolic Dysfunction And Exhaustion Of Virus-specific T Cells During Chronic Infection
Funder

Funding Amount
$749,152.00
Summary
T cells control infections and cancer cells. During chronic infection or tumor development, however, loss of function of T cells prevents efficient clearing of pathogens or cancer cells, a phenomenon termed T cell ‘exhaustion’. We have found that the regulator protein IRF4 controls cellular nutrient usage, growth and function of T cells and that very amounts of IRF4 occur in T cells during chronic infection. We propose to examine the precise role of IRF4 in chronically stimulated T cells.
Identifying The Mechanism And Spectrum Of Activity Of The Antiviral Protein IFITM3
Funder
National Health and Medical Research Council
Funding Amount
$507,200.00
Summary
In response to an infection cells within the body are capable of expressing a range of molecules that help them resist infection, one such molecule is interferon induced transmembrane protein 3 (IFITM3). This recently identified but poorly studied potent antiviral protein dramatically influences the course of influenza infection in both mice and humans. We will explore the mechanisms of antiviral activity of IFITM3 and determine factors important in initiating and retaining expression.
Real Time Models To Inform Prevention And Control Of Emerging Infectious Diseases
Funder
National Health and Medical Research Council
Funding Amount
$549,728.00
Summary
This proposed research addresses the need for real-time tracking of emerging infectious diseases (EID), both spatially and temporally, to inform international and national outbreak response teams, aid in the implementation of real-time containment strategies and ultimately the timely control of emerging infectious diseases. Outcomes will directly enhance & inform policy-making and EID preparedness at a national and international level.
