Development Of A Vaccine For Genital Chlamydia Infections: Protection Against Transmission And Disease Pathology
Funder

Funding Amount
$322,245.00
Summary
Genital Chlamydia infections are the most common sexually transmitted infection in Australia with annual health costs of 90-160 million dollars. Ifection rates in 15-29 year olds are increasing at 15-20% per year. Antibiotics are currently the treatment of choice, however antibiotic resistance is increasing and most infections are asymptomatic and not treated in the absence of screening programs. The project aims to develop a genital Chlamydia vaccine using a combination of novel antigens.
Evolution And Function Of A Novel Lateral Flagellar Locus, Flag-2, In Pathogenic Escherichia Coli

Summary
This project will study how the bacteria that cause infant diarrhoea colonize the intestine and induce disease. We have identified a novel genetic region that allows E. coli to survive and persist in the intestine. Similar genes are also present in closely related organisms. This project will help us to undestand how new diseases evolve and emerge and may lead to the development of new vaccines to protect against infant diarrhoea.
Contribution Of Nuclear Targeting Of The NleE-OspZ Family Of Proteins To Escherichia Coli And Shigella Virulence

Funding Amount
$542,462.00
Summary
This project will study how the bacteria that cause infant diarrhoea colonize the intestine and induce disease. We have identified new bacterial proteins that allow E. coli to manipulate the normal host cell processes involved in killing an invading bacterium. Similar proteins are also present in the closely related organism, Shigella which causes dysentary. We will determine how these proteins act by finding the host cell proteins they bind.
Regulation Of Pulmonary Immune Responses To Subunit Vaccines Against Tuberculosis

Summary
Tuberculosis (TB) remains an enormous health problem world-wide. Improving the effectiveness of anti-TB vaccines is essential for its control. The first approach to improving subunit TB vaccines will be to manipulate the cellular immune response to the vaccine by increasing the positive cytokine signals, or reducing inhibitory effects on the immune response. The second approach is to develop new subunit vaccines to deliver to the lung in order to increase the potency of the protective response.
COMPARATIVE ANTI-BACTERIAL IMMUNITY IN THE URINARY TRACT: DOES ONE SIZE FIT ALL?

Summary
Urinary tract infections (UTI), which start as a bladder infection and often evolve to encompass the kidneys, are among the most common infectious diseases of humans. It is estimated that 40 to 50% of adult healthy women have experienced at least one UTI episode in their lifetime. Bacteria cause most UTI and this study will focus on how these bacteria survive in the urinary tract and will provide key insight into the ways in which human immune responses develop to counteract these bacteria.
Chronic Bacterial Infection And The Generation Of T Cell Memory: Implication For Vaccination Against Tuberculosis

Funding Amount
$547,970.00
Summary
Two million people die from tuberculosis (TB) each year. The immune system is unable to eradicate the TB bacterium, and the type of immune response needed to protect against the disease is poorly understood. We will use animal models of TB infection and sophisticated immunological techniques to decipher how the TB bacterium interacts with the immune sytem and causes disease. We will also develop new TB vaccines that aim to boost the immune response in the lung, the main site of TB infection.
Pathogenomics: New Ways To Exploit Genome Sequence Data From Pathogenic Bacteria.

Funding Amount
$547,372.00
Summary
Bacterial pathogens are locked in an evolutionary battle of survival with their eukaryote hosts. The rapidly evolving genes of medically-important pathogens are generally those required for adaptation to the human host. This project aims to exploit the abundance of available bacterial genome sequences to predict rapid evolution in bacterial pathogens using computational methods. The protein products of such genes offer novel targets for therapeutic intervention.
Structural And Functional Studies On Leptospiral Antigens Central To Pathogenesis

Funding Amount
$287,321.00
Summary
Leptospirosis, also known as Weil's disease and canefield fever, is a potentially fatal disease caused by infection with the bacteria Leptospira. Leptospira is able to infect a broad range of animals including livestock and humans. Human infection typically occurs through contact with water or vegetation that has been exposed to the urine of an infected animal. This project focuses on a key step in the bacterial infection in trying to understand how these bacteria adhere to human cells.
Real-Time Molecular Typing Systems In Infection Control: Design And Effectiveness

Funding Amount
$82,554.00
Summary
MRSA is a major cause of hospital-acquired infection. Molecular typing identifies how a patient managed to contract MRSA in the hospital, and if the strain they have is particularly dangerous. This study will develop a rapid typing protocol then implement it routinely, to determine whether providing this information to infection control staff in a more timely fashion will lead to reduced MRSA infections in hospitals.
