Summary
Aboriginal children have the highest rates of acute and chronic respiratory diseases ever documented. While the underlying cause is socioeconomic disadvantage, the features of poverty that result in disease are not clear. Our current understanding of important risk factors like overcrowding, malnutrition and smoke exposure cannot completely explain the excessively high rates of disease seen in rural and remote Aboriginal communities.

While the underlying cause is socioeconomic disadvantage, the features of poverty that result in disease are not clear. Our current understanding of important risk factors like overcrowding, malnutrition and smoke exposure cannot completely explain the excessively high rates of disease seen in rural and remote Aboriginal communities. This randomised, double-blind, placebo-controlled clinical trial will measure the impact of antibiotic treatment on persistent nasal discharge and rates of transmission of bacterial respiratory pathogens. An innovative study design will test the efficacy of twice daily doses of amoxycillin on newly developed clinical and bacteriological outcome measures. Both the investigators and the Aboriginal community have considerable experience in conducting this type of research and are committed to using a cooperative model of clinical research to reduce disease burden. Ongoing training of Aboriginal health workers in the principles of clinical epidemiology is an essential component of this process. This study will make an important contribution to the medical literature. Despite the deaths of around 10,000 children children from acute respiratory infections each day, very little is known about how antibiotics affect the transmission of some of the principal causative organisms. This project will greatly assist the development of appropriate antibiotic prescribing practices in high-risk populations.Read moreRead less
From Bench To Bedside: A New Treatment For Chronic Rhinosinusitis

Funding Amount
$2,360,520.00
Summary
My research focuses on diseases of the upper airways, in particular chronic relapsing infections and inflammation of the nose and sinus mucosa and on improving wound healing after surgery. My research is translational, aimed at defining new treatments for these diseases. I have invented novel products that improve wound healing after surgery and instruments that help surgeons perform their surgeries in a better and safer way.
A Novel Nitric Oxide-based Treatment For Recalcitrant Staphylococcus Aureus-associated Chronic Rhinosinusitis

Funding Amount
$541,377.00
Summary
Chronic rhinosinusitis (CRS) is a common condition affecting the lives of up to 16% of the population. With yet no cure, the search for effective means of therapy is crucial. Patients with severe disease are most often found to have infection with the bacteria Staphylococcus aureus, associated with more severe symptoms and reduced quality of life. This study will investigate the effectiveness of a novel topical liposome-encapsulated nitric oxide in the treatment of this burdensome disease.
Expression And Secretion Of Large Clostridial Toxins From The Pathogenic Clostridia.

Funding Amount
$332,258.00
Summary
The large clostridial toxins are an important family of bacterial virulence factors that includes toxins from many disease-causing clostridial species. Despite their impact on public health, pathogenesis of disease caused by these bacteria is poorly understood. We will analyse how these bacteria regulate the production and secretion of the large toxins, which will give us a better understanding of the mechanisms of disease causation as well as identifying novel common therapeutic targets.
The Role Of Clostridium Difficile Spore Interactions With The Host In Gastrointestinal Infection And Disease

Funding Amount
$511,467.00
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 have spread through our hospitals and are also found in the community. This project will increase our understanding of how these strains cause severe gut disease, which is critical for the development of improved strategies for preventing and treating these infections and reducing antibiotic use.

Summary
Hospital-acquired infections with the bacterium Clostridium difficile are a major global public health concern with more virulent isolates emerging overseas since 2000. These strains were detected in Australia in 2010 and are now spreading throughout our hospitals. This project will increase our understanding of how these strains cause disease and why they are more harmful, which is critical for the development of improved strategies for preventing and treating these infections.

Some of the world's most important diseases, including important diseases of indigenous chilren and the hospitalised elderly are caused by bacteria that carry a surface coating called a capsule. It is not clear how this capsule is retained by bacteria. Resolution of this question could lead to the development of new disinfectants that will stop hospital-acquired infections, to new reagents that can be incoporated into medical devices where bacteria frequently grow, and new antibiotics.
The Role Of Host Proteases In Modulating Enteric Infectious Disease

Funding Amount
$1,267,155.00
Summary
Bacterial pathogens that cause gut diseases result in 2.5 million deaths per year. The gut is a complex environment consisting of numerous factors that must be balanced to maintain enteric health. When these factors are unbalanced, disease can occur, and infections can cause imbalances. This project will increase our understanding of the role that host proteins play in gut infections, providing knowledge critical for developing improved strategies for disease treatment and prevention.
