DNA sequencing allows us to see into the microbial world in fine detail. This enables us to investigate how bugs like bacteria cause infections and other diseases. In this fellowship, I will use DNA sequencing and analysis to investigate how bacterial infections are transmitted in hospitals and cities, how bacteria become resistant to the antibiotic drugs we use to treat infected people, and how the bacteria that live in our nose and throat contribute to development of asthma in young children.
Evolutionary Events Shaping The Genome Of Cryptococcus Neoformans And Their Effects On Pathogenesis

Summary
Recurring infection in patients with fungal meningitis caused by Cryptococcus neoformans is typically caused by persistence of the original infection rather than reinfection with a new strain. Our analysis of relapse strains shows that small-scale alterations frequently occur at the chromosome ends - regions containing important pathogenesis-related genes in other pathogens. We seek to characterise this microevolution further to understand how it contributes to the success of this pathogen.
Host-pathogen Interaction: The Battle For Supremacy

Summary
This grant will provide salary support for Dr Rowena Bull. Dr Bull's research is focused on understanding the disease process between the human host and the infecting virus. The outcomes of this research will be used to find novel ways to fight viral infections with vaccines and drugs.
Bacterial Pathogenomics: Whole-genome Sequencing To Investigate Infection Transmission, Pathogenesis And Antibiotic Resistance

Summary
As bacterial superbugs – resistant to multiple antibiotics – dominate the headlines, the pipeline for new antibiotics has all but dried up. High-throughput DNA sequencing heralds a golden opportunity for infectious disease research. By studying the entire collection of genes - the genome - of large numbers of multidrug resistant bacterial strains, we aim to better understand the genetic changes that govern the emergence and global spread of superbugs and translate these findings into the clinic.
Structural Analysis Of Poxvirus Immature Particles And Spheroids

Summary
Despite the eradication of smallpox by vaccination, poxviruses remain a threat to public health because of bioterrorist scares from kept variola stocks and because of the possible emergence of other poxvirus pathogens from the extensive animal reservoir. The structural analysis of the assembly of poxvirus will not only improve our knowledge of fundamental processes, highly conserved in DNA viruses, but could also provide valuable targets for the rational design of antiviral drugs.
Improving The Understanding And Management Of Important Human Bacterial Infections

Funding Amount

Summary
This project will focus on two important bacteria, Staphylococcus aureus (Golden Staph), and Enterococcus faecium, both causes of serious infections in hospital and community patients in Australia. Using new technologies, including whole genome sequencing, this project will lead to significant advances in understanding how these bacteria evolve, spread and cause disease. This will lead to new strategies for prevention and management of infections caused by these important bacteria.
Molecular Dissection Of Proteins That Regulate The Invasion Of Toxoplasma Gondii Into Human Cells

Summary
Toxoplasma gondii is an obligate intracellular parasite responsible for congenital birth defects and disease of immuno-compromised individuals. I propose to identify and characterize molecules essential for T. gondii invasion into human cells. These represent novel targets for therapeutic intervention for disease caused by this important organism.

Disorders of the brain, which affect people of all ages, are one of the largest health, economic and social burdens in the developed world. These conditions are chronic, debilitating and have limited symptomatic treatments available. In general, very little is known about the causes of many brain disorders. This project aims to identify the genes and mechanisms that underlie these diseases to enable the development of diagnostic and treatment programs to help reduce the incidence and severity of ....Disorders of the brain, which affect people of all ages, are one of the largest health, economic and social burdens in the developed world.

Nerve cell survival is dependent on both growth-promoting factors and factors released by neurotransmission, which can promote recovery in neurodegenerative conditions by overriding cell death pathways. The molecule responsible for activating death pathways in the nervous system is called p75. This project will investigate how p75 results in cell death, how synaptic signals can prevent the activation of the p75 death pathway and whether blocking p75 function can limit neurodegeneration.
