Molecular Epidemiology And High Resolution Surveillance Of Salmonella Enterica Serovar Typhimurium In Australia

National Health and Medical Research Council
Funding Amount
$583,180.00
Summary
Salmonella typhimurium is a leading cause of the food-borne disease – salmonellosis. It is responsible for considerable morbidity and has an enormous economic cost. Molecular typing is the key to rapidly identify and control outbreaks. This project will employ next generation sequencing technology to develop a new molecular typing scheme. A surveillance system that integrates molecular typing data and epidemiological data will be developed for outbreak investigation and disease prevention.
The Role Chromatin Remodeling Factors In Epigenetic Regulation Of Cardiac Arrhythmia

Funding Amount
$854,135.00
Summary
Cardiovascular diseases kill an Australian every 11 minutes. Arrhythmias are of particular alarm since they can lead to significantly higher risk of serious strokes, heart failure, and overall mortality. We combine fruit fly genetics with next generation human genomics approaches to find and functionally validate new genes and mutations regulating arrhythmia in fruit flies and atrial fibrillation in humans, and this work can rapidly identify new avenues to pursue therapeutic intervention
Characterisation Of Rotavirus Vaccine Escape - Potential For Significant Impact On Vaccination Program
Funder
National Health and Medical Research Council
Funding Amount
$531,689.00
Summary
The introduction of rotavirus vaccines have had enormous impact on improving the health of children worldwide. However, the emergence of vaccine escape strains has the potential to significantly reduce the vaccine effectiveness. This study proposes to characterise strains able to escape vaccine protection.
Directed Evolution Of AAV Capsid Variants For Enhanced Targeted Genome Editing In The Human Liver
Funder
National Health and Medical Research Council
Funding Amount
$386,012.00
Summary
Liver transplantation is often the only treatment option available for patients with severe liver disease, and is complicated by a shortage of donor organs and the need for life-long drug therapy to prevent rejection. Repair of a patient’s own liver by gene therapy is a promising alternative. This project focuses on developing the technology required to undertake precise correction of genetic spelling errors in diseased liver cells without the need to first remove them from the body.
Design And Engineering Of Adnectins For Diagnosis And Therapy
Funder
National Health and Medical Research Council
Funding Amount
$803,152.00
Summary
This project aims to engineer a naturally-occurring human protein, called an adnectin, to produce molecules that are able to bind specific targets in the human body, and as such may be used in the diagnosis and therapy of a range of diseases.
Non-coding RNA Regulation Of Virulence In Enterohaemorrhagic E. Coli

Funding Amount
$389,313.00
Summary
Shiga toxins cause potentially fatal haemolytic uremic syndrome (HUS) and are transferred between bacterial pathogens by bacteriophage (bacterial viruses). We have recently found that the Shiga toxin encoding bacteriophage encodes an unusually large number of non-coding RNAs (RNA regulators of gene expression). This Project aims to understand how these RNA regulators benefit the Shiga toxin bacteriophage and use this knowledge to develop interventions that will prevent expression of the toxin.
Assessing Acellular Pertussis Vaccine Effectiveness: Integrating Transmission Models, Genetics And Cohort Data To Inform Policy
Funder

Funding Amount
$429,597.00
Summary
Between 2009-12 a very large epidemic of whooping cough occurred in Australia. More surprisingly during the course of the epidemic the bacteria that cause whooping cough showed genetic changes that seemed to avoid protection provided by the current vaccine against whooping cough in Australia. This grant seeks to use mathematical models of whooping cough transmission to explain how this occurred and to establish whether alternative vaccination strategies might improve the control of this disease.
Reducing Pertussis Burden By Optimising Molecular Epidemiological Surveillance Of Epidemic Bordetella Pertussis In Australia
Funder
National Health and Medical Research Council
Funding Amount
$487,258.00
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.
Black Death Genomics And The Evolution Of Pathogen Virulence
Funder
National Health and Medical Research Council
Funding Amount
$525,412.00
Summary
The Black Death was one of the most lethal plagues of antiquity and changed the course of human history. We will reconstruct and analyse the evolution of its causative agent – the bacterium Yersinia pestis – sampled from human skeletal remains dating back to the Black Death and beyond. We will determine the mutations that changed the virulence of plague epidemics through time, enabling a unique insight into the most dramatic example of pathogen emergence that has ever been available for study.
Plasmid Specialisation Modules, Microbial Husbandry And Microbiome Resilience
Funder
National Health and Medical Research Council
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.
