Critical Infection: Ecological Solutions To Antibiotic Resistance
Funder
National Health and Medical Research Council
Funding Amount
$561,362.00
Summary
The applicant will apply new types of microbial data and diagnostic tools to early interventions in the critically ill and directly test their impact on clinical outcomes. He will also introduce novel therapies to restore antibiotic susceptibility to enteric bacteria and examine the clinical and microbiological effects of antibiotic decontamination of the critically ill in newly funded project grants. Overlapping research themes all link directly to his clinical and professional roles.
Robust Bioinformatics For Predicting Bacterial Pathogens From Microbiome Sequencing
Funder
National Health and Medical Research Council
Funding Amount
$644,151.00
Summary
We propose to develop new methods for the identification of microbial pathogens using High Throughput DNA Sequencing (HTS). Study of the microbiome - the genes encoded by the assemblage of microbial species present in an environment - using HTS technologies is revolutionising our understanding of human-microbe interactions. Our proposed work includes fundamental computational and theoretical advances and applying these techniques to solve critical problems in pathogen detection.
Women with diabetes in pregnancy and their babies are more likely to have health problems, e.g. preeclampsia, being born early, or admitted to neonatal intensive care unit. We know that lowering mum’s blood glucose to the levels found in women without diabetes is important but does not prevent problems completely. The purpose of these studies is to look at the other parts of metabolism that are different in women with diabetes e.g. blood fats, so we can understand if we should address them.
Should You Be Eating That? Food-derived Bacteria And Their Role In Treating Disease
Funder
National Health and Medical Research Council
Funding Amount
$1,405,182.00
Summary
The clinical application of medicines based on the microbes that exist as part of microbiomes is now a reality. Despite these rapid advances understanding how the bacteria are transmitted and recolonise after disruption is essential. Our preliminary data suggests that the average Australian adult consumes over 10 million bacteria per day in their diet. This project seeks to understand these relationships and how they can be exploited to develop the next generations of microbiome based medicine.
Prevention Of Otitis Media With Probiotics In Indigenous Children
Funder
National Health and Medical Research Council
Funding Amount
$100,531.00
Summary
The project is searching for ‘good’ bacteria in the upper airways of Aboriginal and Torres Strait Islander (A&TSI) children that have the ability to inhibit the growth of bacteria that causes middle ear disease. These ‘good’ bacteria constitute a possible probiotic and will be matched to commercially available probiotic strains. These probiotic strains will then be used to recolonise the upper airways of A&TSI children to determine whether we can reduce the recurrence of middle ear disease.
Closing The Clinical Translation Gap Of The Gut Microbiome In Chronic Diseases
Funder
National Health and Medical Research Council
Funding Amount
$1,337,350.00
Summary
The gut microbiota is important for human health and disease but knowledge transfer to clinical practice is lacking. This proposal will investigate how diet & gut microbiota changes connect with physical symptoms, mental health & behavioural issues in chronic diseases, using cystic fibrosis & autism spectrum disorder as models of disease. Improved understanding can improve management, assist in developing targeted therapies & is key to providing real-world solutions to improve outcomes.
The Relationship Between Maternal And Infant Dietary Intake Of Fermentable Fibre, Gut Microbiota, Short Chain Fatty Acids And Allergic Disease And Asthma: A Population-derived Birth Cohort Study
Funder
National Health and Medical Research Council
Funding Amount
$871,700.00
Summary
The proposed study will involve the Barwon Infant Study (BIS) cohort of 1074 infants to provide the first systematic investigation of the hypotheses that the epidemic of allergic disease and asthma in many parts of the world relates to the paucity of fermentable fibre in the modern diet, and that the protective effect of fermentable fibre is mediated by changes in the organisms that colonise the gut and the metabolites that they produce.
Modelling The Biology And Transmission Of Influenza Virus - Learning From 1918-19 And Other Outbreaks
Funder

Funding Amount
$114,222.00
Summary
In preparing for a future pandemic of influenza, it is important to learn as much as possible from what happened in the past, particularly from the devastating pandemic of 1918-19. This project will collate detailed information about the spread of influenza in past outbreaks and create a publicly accessible data-base. Mathematical methods will be used to analyse historic and contemporary data, so as to provide better understanding of the spread of influenza, and of the likely effects of social a ....In preparing for a future pandemic of influenza, it is important to learn as much as possible from what happened in the past, particularly from the devastating pandemic of 1918-19. This project will collate detailed information about the spread of influenza in past outbreaks and create a publicly accessible data-base. Mathematical methods will be used to analyse historic and contemporary data, so as to provide better understanding of the spread of influenza, and of the likely effects of social and medical measures for its control. An important theme of the project is to consolidate our knowledge about how past exposure to non-pandemic influenza could provide short-lived protection against any new pandemic, and to explore the implications of this for prevention today. Another theme is to explore the severity of influenza during pandemics, and to identify social and medical factors that might reduce the dose of virus transmitted, or otherwise reduce the severity of infection. The insights from the modeling will also help to identify gaps in knowledge and understanding about the basic biology of influenza, stimulate new research to fill those gaps, and thus offer the prospect of more effective vaccines and treatments for the future control of influenza.Read moreRead less
Faecal Microbiota Transplantation For Active Ulcerative Colitis - A Randomised Controlled Trial: Clinical, Microbial & Immune Outcomes
Funder
National Health and Medical Research Council
Funding Amount
$700,126.00
Summary
This is a placebo controlled clinical trial to see whether giving healthy donor faeces to people with active ulcerative colitis can get them into remission. We will also examine how long the donor microbiome stays in the recipients stool, and examine the effects of faecal transplantation on the immune response in the lining of the colon in recipients.
How Do Antibiotics Affect The Gastrointestinal Microbiome In Children?
Funder
National Health and Medical Research Council
Funding Amount
$215,000.00
Summary
Antibiotics, while vital, have potentially long term negative effects on antimicrobial resistance and other aspects of health. Microorganisms living in the human intestine, collectively the gastrointestinal microbiome, are believed to play a key role. Antibiotics can change the microbiome, and this is potentially important in children due to the longevity of health effects. We aim to determine the effect of different antibiotics (broad versus narrow) on the microbiome over time in children.
