Summary
Food allergies now affect more than 1 in every 10 children. Recently, babies have been found to be at risk of developing a food allergy even before they start eating solid foods. We have discovered that baby immune responses can be improved by mothers eating more eggs during the first weeks of breastfeeding. Thus we are undertaking this research trial to determine whether mothers regularly eating more eggs and peanuts during pregnancy and breastfeeding will reduce food allergies in their babies.
Dietary Modulation Of Maternal Gut Flora With Oligosaccharides In Pregnancy As A Novel Allergy Prevention Strategy

Summary
Declining intake of dietary fibre is a major factor implicated in the changing profile of healthy gut bacteria, and the associated increase in many inflammatory diseases including childhood allergy. This clinical trial aims to confirm findings in animal studies that increased dietary fibre in pregnancy can prevent allergy in the offspring, by favourably influencing metabolism and immune function during pregnancy.
Allergic disease affects more than one in five Australian children. What foods a mother eats during pregnancy and breastfeeding, as well as when to introduce solid foods to babies, is thought to be critical in reducing the increasing burden of allergies in our Australian community. I hope to use this fellowship to discover what dietary factors put children at risk of developing a food allergy, and ways we can reduce that risk.
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

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.

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

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

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.
