Mechanisms Of Antibiotic-induced Persistent Bacterial Infection

Funding Amount
$632,048.00
Summary
Golden staph still causes significant human infections and resistance to antibiotics is an ever growing problem with this bacteria. This project will determine how resistance to some antibiotics is also changing the bacteria to promote persistent, difficult to treat infections. The insights from this study will help understand evolution of this bacteria, and help design new strategies for management.
Reducing Pertussis Burden By Optimising Molecular Epidemiological Surveillance Of Epidemic Bordetella Pertussis In Australia

Summary
Australia has experienced a prolonged epidemic of pertussis from 2008 to 2012 and is currently experiencing another epidemic. In this project, we aim to elucidate the evolutionary dynamics of the epidemics by genome sequencing and develop a practical high throughput culture independent method for epidemiological typing. The outcomes will be highly significant for surveillance of pertussis infections and designing strategies for control and prevention of pertussis.
Once treatable infections are becoming deadly because bacteria are developing broad antibiotic resistance. New medicines are urgently needed. Microbes themselves are the richest known source of new antibiotics but finding the 'good bugs' is like finding a needle in a microbial haystack. This project will use state-of-the art science to screen a previously overlooked source of rich microbial biodiversity and find new antibiotics.
Plasmid Specialisation Modules, Microbial Husbandry And Microbiome Resilience

Funding Amount
$645,005.00
Summary
The epidemiology of plasmids is chiefly determined by small genetic modules that control their entry to cells, their stability after entry, and their capacity to exclude other related plasmids. Understanding this is important for understanding transmission of antibiotic resistance. It is also essential for our newly proven approach to remove resistance plasmids from bacteria.
Understanding The Disease Burden And Antibiotic Resistance In Patients With Bloodstream Infections Caused By Enterobacteriaceae In Australia
Funder
National Health and Medical Research Council
Funding Amount
$135,285.00
Summary
This study aims to establish the epidemiology of bloodstream infections caused by Enterobacteriaceae (enteric or gut bacteria) in Australia, by examining infection rates, types of antibiotic resistance present, and which treatments optimise clinical outcomes.
Understanding Virulence Of Invasive Staphylococcus Aureus

Funding Amount
$772,711.00
Summary
Staph aureus (Golden staph) is a major cause of disease in humans. In this project we will use state-of-the-art molecular biology and genomics to fully understand the mechanisms of virulence in this pathogen. This information will inform future approaches to development of therapeutics, as well as the use of genomics in clinical microbiology and disease management.
Molecular Epidemiology Of Mycobacterium Tuberculosis Infection In The Northern Territory, Australia
Funder
National Health and Medical Research Council
Funding Amount
$122,714.00
Summary
The Northern Territory (NT) of Australia has the highest jurisdiction-specific rates of tuberculosis (TB) in Australia, and TB is a disease that disproportionately affects Indigenous people. The factors that contribute to the spread of TB in the NT are incompletely understood. We plan to use technology known as “whole genome sequencing” of bacterial DNA to better the understanding of the spread of TB in the NT. This will help guide TB control policies.
A One Health Approach To Assessing The Threat Of Clostridium Difficile To Australia’s Biosecurity: A Genomic Investigation Of Human, Animal And Environmental Isolates
Funder
National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
Clostridium difficile is a bacterium that causes life-threatening diarrhoea in humans and animals and is a major public health issue in Australia. This project will study the genetic make-up of the bacterium and identify factors contributing to the emergence, evolution, and spread of C. difficile. This knowledge will be essential in guiding effective public health interventions and reducing deaths from C. difficile infection in humans and animals.
Understanding The Contribution Of SRNAs To Antibiotic Resistance In Staphylococcus Aureus

Funding Amount
$587,424.00
Summary
Golden Staph is a major problem in Australian hospitals. This project will use cutting edge technology to investigate how Golden Staph responds to and resists antibiotics used to treat human infections, leading to new strategies for the prevention and treatment of antibiotic resistant bacteria.
This project uses latest genomic technologies to advance our understanding of how bacteria cause disease and finding new antibiotics/approaches to stop the spread of multi-drug resistant hospital superbugs.
