Summary
Breast cancer is the most invasive cancer in females, affecting 1 in 9 women before the age of 85. Normally cells only divide when they receive a stimulus from a hormone or growth factor. The PI3K pathway responds to these stimuli and has been implicated in cancer when cells divide uncontrollably and invade surrounding tissue. We have identified a potential cancer suppressing gene, 4-ptase-2 that turns off the PI3K growth signals. We aim to characterize the role of 4-ptase-2 in breast cancer.
Understanding The Development And Spread Of Pan Resistance In Acinetobacter Baumannii

Funding Amount
$2,339,215.00
Summary
Resistance to all antibiotics available for treatment of bacterial infections is a cause for global concern (Word Health Organization, US Centres for Disease Control) as it also compromises therapies relying on antibiotics such as transplantation and cancer chemotherapy. Extensively antibiotic resistant Acinetobacter baumannii, mainly causes hospital-acquired infections. This project will seek to track different types of these bacteria as they repeatedly spread around the world.
A New Mechanism For Transposition Of Antibiotic Resistance Genes

Funding Amount
$501,839.00
Summary
Understanding how antibiotic resistance genes are acquired by bacteria is important if we are to understand how bacteria become resistant in so many antibiotics, limiting treatment options. This project will investigate the way a family of insertion sequences captures and then moves resistance genes. This mechanism contributes to resistance in many bacterial pathogens including ones that are resistant to many different antibiotics.
Pathways To Extensive And Pan Antibiotic Resistance In The Globally Disseminated Acinetobacter Baumannii GC2 Clone

Funding Amount
$865,004.00
Summary
The project will study the evolution of a Acinetobacter baumannii clone that is found all around the world, and has become resistant to most or all of the currently available antibiotics. Resistance has been acquired in a series of steps, and the resistance genes present and the events involved will be used to understand the globalization process. The increased understanding of resistance development should assist in controlling untreatable infections and in preserving antibiotics.
New Strategies To Target Multiple Drug Resistance In Clinically Relevant Fungal Infections.

Funding Amount
$378,925.00
Summary
The emergence of multiple drug resistance (MDR) in the community and hospitals is considered a major threat to public health. Fungal bloodstream infections with opportunistic Candida species are of particular concern. Azoles are the most widely used class of antifungals in clinical use, but their efficacy is severely limited by the development of MDR. This project will employ a comprehensive, cross-disciplinary approach to develop novel small-molecule therapeutics for combatting fungal MDR.
Role Of IS26 In Antibiotic Resistance Gene Recruitment, Dissemination And Expression

Funding Amount
$457,879.00
Summary
Antibiotic resistance is increasing, compromising the efficacy of front-line antibiotics. Untreatable infections due to bacteria that are resistant to all available antibiotics are being seen more often. To control the spread of resistance, an understanding of how resistance arises and is spread among bacteria is needed. This requires information about how the genetic elements that mobilize them work. This project will study one of the most important of these elements.
Spatial Simulation Modelling Of Containment Strategies For Pandemic Influenza

Summary
This research will develop a spatial simulation model to predict the spread of pandemic influenza within Australia. The resulting software program will be readily usable by disease managers, both during and prior to an outbreak, to predict the effect of various containment measures on the size, rate and location of disease spread, through a city, state or the nation. Deployed in _real time� after an outbreak has started in Australia, it will be used to predict infection spread and the containmen ....This research will develop a spatial simulation model to predict the spread of pandemic influenza within Australia. The resulting software program will be readily usable by disease managers, both during and prior to an outbreak, to predict the effect of various containment measures on the size, rate and location of disease spread, through a city, state or the nation. Deployed in _real time� after an outbreak has started in Australia, it will be used to predict infection spread and the containment effect of a range of interventions. The model would use data obtained during initial stages of the outbreak to refine the model, so allowing accuracy in daily spread prediction; similar use of spatial models occurred during the 2001 Foot and Mouth Disease (FMD) outbreak in the UK. In a pre-pandemic period the simulation model will be available to predict the containment effect of a range of response measures, such as travel restrictions, workplace and school closures, vaccination and antiviral usage. Specifically, this project will apply the simulation model to determine optimal use of limited resources such as the _when and where� targeting of antiviral drugs and initial supplies of vaccine.Read moreRead less
Antibiotic resistance increases mortality and costs in the Intensive Care Unit (ICU), but the impact of antibiotic therapy has not been adequately studied. We propose to characterise the behaviour of key elements of the bacterial microflora (resistant bacteria and major resistance genes) in response to antibiotics. We have developed new rapid diagnostics to harness these data and this proposal has the potential to greatly improve diagnostic speed and accuracy and thus clinical outcomes.
How Are Klebsiella Pneumoniae Infections Acquired In Hospital?

Summary
Klebsiella pneumoniae (Kp) bacteria are among the top causes of hospital infections and are often resistant to a wide range of antibiotics. While some hospital bugs are well-studied, we are considerably behind in our understanding of Kp, which can be carried in our bodies as a commensal without causing disease. Bacterial genomics will be used to dissect how Kp infections are acquired in hospital, including investigating the evidence for hospital transmission and the role of commensal carriage in ....Klebsiella pneumoniae (Kp) bacteria are among the top causes of hospital infections and are often resistant to a wide range of antibiotics.
