The Role Of The Chemosensory Receptors Of The Enteric Pathogen C. Jejuni In Virulence And Host - Bacterial Interactions

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.
Immuno-metabolic Interactions Of The Fungal Superbug Candida Auris

Funding Amount
$674,105.00
Summary
Infections threaten hospital patients and undermine our ability to use advanced medical treatments for conditions such as cancer. Candida auris is an emerging superbug causing infections in hospitals and nursing homes that are commonly resistant to front-line antifungal therapy. To build the knowledge foundation for improved treatments, this proposal aims to define how C. auris escapes immune defences and understand the metabolic mechanisms that shape immune responses and infection outcomes.
Early Origins Study Of Cystic Fibrosis-related Diabetes

Funding Amount
$128,188.00
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.
Antibiotic Potentiators As An Alternative Therapeutic Option For The Treatment Of Extensively Drug-resistant Gram-negative Infections

Funding Amount
$856,858.00
Summary
Antibiotic mono-therapies are increasingly ineffective for hard-to-treat bacterial infections, forcing clinicians to rely on combinations of antibiotics. Our project has identified compounds that have weak to no antimicrobial potency in their own right, yet when combined with an existing antibiotic they potentiate its activity and restore its ability to treat resistant infections. These antibiotic potentiators are exciting alternatives to current therapies with reduced risk of induced resistance
Star Polymers As Novel Antimicrobial And Immunomodulatory Agents
Funder
National Health and Medical Research Council
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.
Identifying How The Enteric Nervous System Regulates Gut Permeability In Autism

Summary
This project aims to investigate causes of increased gut permeability in neurological disorders including autism and will apply neuroscience, immunological and microbiology techniques to clarify the causes of increased gut permeability in a well-characterised genetic mouse model of autism.
