Probiotic Prophylaxis Of Spinal Cord Injury Urinary Tract-Infection TherapeUtic-Trial (ProSCIUTTU)

Summary
Urinary Tract Infections (UTI) are common in spinal cord injury (SCI) and about 2-year occur in SCI. Antibiotic resistance is also common in SCI. UTI are harder to treat with high rates of antibiotic resistance and this often leads to hospitalisation with significant health and economic consequences to the SCI community and country. Probiotics may prevent UTI and treat people colonised with resistant organisms. Unlike alternatives like antibiotics, they do not worsen antibiotic resistance.
Therapeutic Targeting Of Interleukin-22 For Severe Paediatric Urinary Tract Infection And Associated Renal Complications

Summary
Urinary tract infections are among the most common bacterial infections and are associated with the development of chronic kidney disease. The bacteria that cause these infections are becoming increasingly resistant to antibiotic therapy. Therefore, new strategies that target the immune system rather than the bacteria are urgently needed. This study will provide evidence for re-purposing novel immunotherapies targeting the protein interleukin-22 that are being developed for other diseases.
Role Of Macrophages In Uropathogenic E. Coli Infections

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 Randomised Placebo-controlled Trial Of Antibiotics To Prevent Urinary Tract Infection In Children

Summary
This study is needed to determine whether a common clinical practice long-term antibiotic treatment for children following urinary tract infection (UTI) - is safe and effective in preventing further UTI and if so, whether all appropriate children are being treated. UTI will affect about 10% of Australian children by high school age (88,000 children per year). Because UTI may damage the kidneys, the management priority for children with UTI has been prevention of further infection. Currently this ....This study is needed to determine whether a common clinical practice long-term antibiotic treatment for children following urinary tract infection (UTI) - is safe and effective in preventing further UTI and if so, whether all appropriate children are being treated. UTI will affect about 10% of Australian children by high school age (88,000 children per year). Because UTI may damage the kidneys, the management priority for children with UTI has been prevention of further infection. Currently this means the identification of children thought to be most at risk of recurrent UTI by renal tract imaging. Those found to have reflux of urine from the bladder to the kidney (present in about 30% of those with UTI) are then placed on antibiotics fro 2-5 years. Unfortunately there has never been a properly designed trial to test whether antibiotics do really prevent UTI and if so, whether children with reflux are the appropriate and only group requiring treatment. Long term antibiotics may in fact do more harm than good because of side effects like skin, bowel and blood problems and because resistant bacteria may develop. The design of this study involves the random allocation of placebo or antibiotic (cotrimoxazole, the usual antibiotic given in this case) to about 800 children after their first symptomatic UTI. These children are treated and followed for one year to determine the rate of futher UTI in both groups. Any difference in outcome between the two groups of children will be because of the antibiotic treatment. This study may prove long-term antibiotics are ineffective and therefore should not be routinely used. In this case investigation of children to detect vesicoureteric reflux would serve little purpose and should be abandoned. Alternatively antibiotic treatment may be shown as effective treatment for preventing further UTI and in this case the study will clearly identify those children who will benefit.Read moreRead less
Halting The Spread Multidrug Resistant Uropathogenic E. Coli

Summary
Uropathogenic Escherichia coli (UPEC) is a major cause of urinary tract infection (UTI) and increasingly associated with resistance to multiple antibiotics. This project will study the virulence of multidrug resistant UPEC and use this knowledge to develop new approaches to treat and prevent UTI. The outcomes will be applicable to one of the most common infectious diseases of humans and have broad-reaching impact on our understanding of other infections caused by Gram-negative pathogens.
Uropathogenic Escherichia coli (UPEC) are 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 worldwide. This project addresses the mechanisms by which E. coli ST131 can colonise the urinary tract and cause disease. The outcomes of this project will be a better understanding of how E. coli ST131 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

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.
