Summary
Campylobacter jejuni is the greatest cause of bacterial gastroenteritis in the world. Consumption of contaminated meat or untreated water leads to disease often requiring hospitalisation. Campylobacter infection is also linked to the development of neoroparalytic disorders and reactive arthritis. This project aims to determine how this pathogen utilises surface molecules to sense its environment and cause disease. This information may be exploited to develop new treatments for mucosal infections ....Campylobacter jejuni is the greatest cause of bacterial gastroenteritis in the world.

Characterisation Of Porphyromonas Gingivalis And Treponema Denticola Interactions In The Development Of A Pathogenic Biofilm

Funding Amount
$566,200.00
Summary
Gum disease (periodontitis) is an inflammatory disease caused by bacterial pathogens that is the major cause of tooth loss in adults. It is also associated with systemic diseases such as cardiovascular disease. In this study we will determine the mechanisms by which two bacterial species work together to produce the pathogenic dental plaque that causes disease.
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.
Antibiotic Treatment Of Male Partners To Reduce Recurrence Of Bacterial Vaginosis In Women: A Randomised Double-blind Controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$636,674.00
Summary
Bacterial vaginosis (BV) is the most common vaginal infection in women. Healthy bacteria are lost and replaced by bacteria that cause unpleasant discharge and odour. BV puts women at increased risk of sexually transmitted infections, HIV, miscarriage and preterm delivery. Over 50% of women given antibiotics get BV back again. Studies suggest these bacteria are being sexually transmitted. We are conducting a trial of antibiotic treatment of women and their male partners to improve BV cure.
Early Origins Study Of Cystic Fibrosis-related Diabetes

Funding Amount

Summary
Cystic Fibrosis is a genetic condition that causes recurrent lung infections and early death. Some patients also develop diabetes which causes a more rapid decline. Many young children with CF have “pre-diabetes” but guidelines do not recommend screening high glucose in this group. In order to intervene early, this study aims to determine if “pre-diabetes” in very young children with Cystic Fibrosis causes poorer growth, lung function or an increase in bacterial infections to.
Star Polymers As Novel Antimicrobial And Immunomodulatory Agents

Funding Amount
$945,908.00
Summary
The rise in antibiotic resistance in bacteria is considered as a major public health threat that is not being met by antibiotic research. This project will modify a novel star polymer that we have shown kills antibiotic resistant bacteria but does not induce resistance. The project will make and characterise new versions of the star polymer to produce antimicrobial materials that target and kill the multi-drug resistant bacteria that are a major cause of bacterial infections and death.
Comparative Expression Studies To Identify Cellular Factors Promoting Hendra Virus Replication For A Comprehensive Understanding Of Hendra Virus Pathogenesis
Funder
National Health and Medical Research Council
Funding Amount
$374,619.00
Summary
Hendra virus (HeV) is an emerging pathogen indigenous to fruit bats. HeV is associated with limited outbreaks with high mortality in domesticated animals and humans. To advance the understanding of HeV-related pathogenesis, we will perform comparative studies in bat and human cell lines to recognise differences in virus-host cell interactions leading to a comprehensive understanding of the HeV life cycle and pathogenesis.
Innovative Antimicrobial Treatments For Successful Bone Allografts

Funding Amount
$473,706.00
Summary
Bone healing sites are commonly infected, and this is associated with adverse clinical and significant socioeconomic outcomes. These studies will determine whether our novel antimicrobials can be used to reduce bone infections by studying the combination of antimicrobials and bone in laboratory and bone fracture studies whilst minimising the potential of developing antibiotic resistance.
An Investigation Into The Molecular Basis Of MAIT Cell Recognition Of Vitamin B Based Metabolites
Funder
National Health and Medical Research Council
Funding Amount
$883,762.00
Summary
Mucosal associated invariant T cells (MAIT cells) are an abundant T-cell population in humans, that is found mostly in the gastrointestinal mucosa. We have recently shown that MAIT cells can be activated by metabolites of vitamin B. This proposal will investigate how the MAIT cells "see" vitamin B metabolites. This research will pave the way for novel therapeutics that can modulate MAIT cell activity.
A Targeted Molecular Approach To Treating Scabies And Associated Bacterial Infections.

Funding Amount

Summary
Chronic infestation of human skin with parasitic scabies mites is a severe health burden in Australian Indigenous communities and other disadvantaged communities around the world. Secondary infections with bacteria exacerbate this skin problem, with long-term, systemic and often fatal consequences including rheumatic heart disease. Analyses of the scabies mite genome and associated bacteria will accelerate biomedical research toward improved treatment and control of this neglected disease.
