Summary
Urinary tract infections (UTI) are one of the most common types of infections in humans. They are also a major cause of septic shock, a condition with high fatality rates. Uropathogenic Escherichia coli (UPEC) are the major microbes causing UTI in humans. This project addresses the role of an immune cell type, the macrophage, in UPEC-mediated disease. The outcomes of this project will be a better understanding of how UPEC causes disease, and potentially new treatment regimes for UTI.
A Matter Of Life And Death: Defining Novel Interactions Between Uropathogenic E. Coli And Macrophages That Influence UTI Pathology

Summary
Urinary tract infections (UTI) are one of the most common types of infections in humans. Uropathogenic Escherichia coli (UPEC) are the major microbes causing UTI in humans. This project will define novel interactions between UPEC and macrophages, an important immune cell involved in the control of UTI. The outcomes of this project will be a better understanding of how UPEC causes disease, and potentially new treatment regimes for UTI.
The Dual-edged Sword Of Zinc As An Innate Immune Antimicrobial Weapon Against Uropathogenic E. Coli

Funding Amount
$784,428.00
Summary
Infectious diseases are a major global health threat, and urinary tract infections (UTI) are one of the most common infectious diseases. Most UTI are caused by uropathogenic E. coli (UPEC). In order to cause infections, UPEC must be able to overcome our body’s first line of defence, the innate immune system. This project seeks to understand how our innate immune system uses zinc to combat bacterial infections, and how UPEC is able to defend against such responses in order to cause disease.
Understanding Uropathogenic E. Coli-mediated Subversion Of Innate Immunity

Funding Amount
$932,536.00
Summary
Urinary Tract Infections (UTI) are one of the most common bacterial infections. Uropathogenic E. coli (UPEC) are the primary cause of UTI and increasingly associated with antibiotic resistance. UPEC use an array of strategies to overcome the innate immune system, which provides the first line of defence against infectious diseases. This project aims to understand how UPEC overcomes innate immunity, with the ultimate goal of devising new approaches for the treatment and prevention of UTI.
The Current Multidrug Resistant Escherichia Coli Pandemic: Exploring Novel Therapies Against The Predominant Culprit E. Coli ST131.

Funding Amount

Summary
Escherichia coli ST131 is a pandemic superbug. Like MRSA, E. coli ST131 infections are resistant to multiple antibiotics and can become life threatening. This study will show how adhesion can be the 'Achilles' heel' of this global pathogen and how blocking E. coli ST131 adhesion offers an alternative therapy for multidrug resistant human infections. As we are left with no effective antimicrobials to treat E. coli ST131 infections, this work will provide novel outcomes that are sorely needed.
Role Of Autotransporter Proteins In Uropathogenic E. Coli Infections

Summary
Urinary tract infections (UTI) are among the most common infectious diseases of humans. Uropathogenic E. coli (UPEC), the primary cause of UTI, utilize a range of adherence mechanisms to colonize the urinary tract. In this project we will characterise the function and mode of secretion for one important class of UPEC adherence factors – autotransporter proteins. This work may inform new approaches to prevent UTI, an urgent need given the rapid increase in resistance to antibiotics among UPEC.
Functional And Genomic Analysis Of The Globally Disseminated Multidrug Resistant Escherichia Coli ST131 Clone

Summary
Uropathogenic Escherichia coli (UPEC) is a major cause of urinary tract infections (UTI) and sepsis. Recently, a highly virulent clone of UPEC (E. coli ST131) that is resistant to multiple types of antibiotics has emerged and spread worldwide. This project uses genomic and high-throughput functional analysis methods to understand E. coli ST131 virulence and resistance.

The Arthroplasty Surgical Antibiotic Prophylaxis (ASAP) Study

Funding Amount
$3,509,985.00
Summary
The demand for total joint replacement surgery will double over the next decade. Infection involving the surgical wound is a devastating complication of this surgery. Half of all infections are due to methicillin resistant Staphylococcus (such as MRSA) and Enterococcus. This multicentre randomised controlled trial aims to investigate whether the addition of vancomycin at the time of surgery reduces the incidence of surgical wound infections; is safe and is cost-effective.
Targeted Pelvic Floor Muscle Training For Urinary Incontinence After Radical Prostatectomy: A Randomised Controlled Trial With Embedded Physiological Studies

Funding Amount
$966,377.00
Summary
Prostatectomy is a common treatment for the most common cancer in men. Survival is good, but many develop debilitating urinary incontinence. Past pelvic floor muscle training has had limited effect, but recent work has changed understanding of how muscles control continence and compensate for surgery. This clinical trial compares innovative training individually tailored to optimise continence, usual exercise and no treatment, and aims to identify men most likely to benefit from treatment.
Extending The MIS BAIR Randomised Trial Of BCG To Prevent Childhood Allergy And Infection

Funding Amount

Summary
BCG (used till recently to prevent tuberculosis) is a potential low cost and readily available vaccine which could reduce the rates of allergy and infection in Australian children. We propose to extend our existing NHMRC-funded trial, which studies whether BCG vaccinatinon given at birth prevents the development food allergy, eczema and infection in the 1st year of life, to see if this effect continues until 5yrs of age. At this age, we can also see if BCG vaccination at birth prevents asthma.
