Fungi are increasingly causing life-threatening infections. Little is known about the mechanisms underlying these infections. We will compare the genomes of high and low virulent fungal strains to gain insides into the basis of these differences by using C. gattii as model of a globally highly pathogenic fungus. The findings will be generalized by comparing the obtained results with the genomes of other important pathogenic fungi to develop a scientific basis for better treatment strategies.
The Role Of MHC In Immune Evasion: Insights From A Contagious Cancer
Funder
National Health and Medical Research Council
Funding Amount
$260,677.00
Summary
An aggressive, contagious cancer, Devil Facial Tumour Disease (DFTD), has emerged in the Tasmanian devil population. We are using the devil tumour to study how cancer is recognized by the immune system and ways in which cancer can 'escape' from the immune system. This research will contribute to our understanding of human cancer and help save an iconic Australian species from extinction.
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.

Summary
Dengue and chikungunya are mosquito-transmitted viruses that present significant public health threats to Australia and the Asia-Pacific. This project will investigate whether dengue and chikungunya can adapt in response to a bacterium that limits replication of the viruses in the mosquito. The research will provide critical data to inform new mosquito control methods aimed at breaking the virus transmission cycle. More broadly, the research will allow us to understand how viruses adapt to strat ....Dengue and chikungunya are mosquito-transmitted viruses that present significant public health threats to Australia and the Asia-Pacific.

DNA Barcoding Of Pathogenic Fungi As The Basis For The Development Of Novel Standardized Diagnostic Tools

Funding Amount
$560,398.00
Summary
Fungal infections are increasing and have major health impacts, with a high economic burden. Timely initiation of therapy is the key to improve patient outcomes. However, reliable identification tools for fungal pathogens are lacking. We will use comparative genome analysis to develop unique fungal signatures (DNA barcodes) and establish an online database to allow for rapid identification for diagnosis in the clinical setting and as a quarantine tool for border protection.
Uncovering vertebrate lifespan biodiversity with whole genome sequencing. This project aims to integrate existing data on the genetic mechanisms of lifespan evolution in model systems with a novel combination of whole genome sequencing and comparative phylogenomics to reveal the common genomic signatures of lifespan evolution in vertebrates. Expected outcomes include a perspective on the evolution of lifespan, a topic of major health interest for Australia and the rest of the developed world.

This project aims to integrate existing data on the genetic mechanisms of lifespan evolution in model systems with a novel combination of whole genome sequencing and comparative phylogenomics to reveal the common genomic signatures of lifespan evolution in vertebrates. Expected outcomes include a perspective on the evolution of lifespan, a topic of major health interest for Australia and the rest of the developed world. This will provide significant benefits, such as long-term implications for aging research, with possible business applications. It will also increase Australia’s visibility and competitiveness in the developing field of bioinformatics.Read moreRead less
Genome dynamics following plastid endosymbiosis. Plastid endosymbiosis events (enslavement of an algal cell inside of a host cell to form a plastid) are difficult to pinpoint because the genomic data required for a broad array of species are rarely available. Furthermore, the classical method used to infer endosymbiotic gene transfers is being criticised. This project will elucidate the origin of chlorarachniophyte and dinoflagellate plastids and characterise the genome dynamics following endosy ....Genome dynamics following plastid endosymbiosis. Plastid endosymbiosis events (enslavement of an algal cell inside of a host cell to form a plastid) are difficult to pinpoint because the genomic data required for a broad array of species are rarely available. Furthermore, the classical method used to infer endosymbiotic gene transfers is being criticised. This project will elucidate the origin of chlorarachniophyte and dinoflagellate plastids and characterise the genome dynamics following endosymbiosis. It uses densely sampled genome data obtained with high-throughput sequencing technologies. Simulation studies will be used to evaluate methods for inferring endosymbiotic gene transfer and alignment-free methods will be used to improve phylogenomic pipelines.Read moreRead less
Comparative Analysis Of Human And Kangaroo Leishmania: Defining Human Pathogenicity Genes

Funding Amount
$539,334.00
Summary
Leishmaniasis is a global infectious disease affecting millions and killing thousands each year. This project will utilise the recent discovery in Australia of a related pathogen to identify novel parasite genes and pathways involved in virulence in humans. The latest techniques in comparative genomics and molecular biology will identify the genes that cause human disease . Appropriate genes will then be used to develope a novel vaccine using the Australian parasite.
