Summary
Infectious disease outbreaks are driven by complex interactions between humans, animals, vectors, and the environment. Globally, outbreaks have been increasing in frequency and magnitude, e.g. Ebola and SARS. There is an urgent need to improve public health intelligence by accurately identifying the causes, timing, and hotspots. This project will develop advanced modelling strategies for improving our understanding of outbreaks, and optimise public health interventions to protect human health.
Spatiotemporal Risk Assessment Of Emerging Infectious Disease Threats To Australia

Funding Amount
$641,204.00
Summary
Emerging infectious diseases (EIDs) such as dengue and influenza pose a constant and growing threat to Australians. We live in an increasingly connected world in which EIDs cross borders and oceans, carried by infected people or vectors. This research will build an evidence base for allocation of resources to surveillance and preventive health programmes aimed at mitigating the threat of EIDs, through identifying high-risk sources, routes of introduction, incursion locations and communities.
Analysis And Regulation Of Leptospiral Virulence Factors.

Summary
Leptospirosis is a globally important infectious disease caused by Leptospira spp. This project aims to identify and characterise factors which play a role in disease development by knocking out genes, then investigating the impact on overall gene-protein expression in the mutant strain and its ability to cause disease. This will allow us to gain insights on mechanisms by which Leptospira spp. cause disease, leading to development of better methods of disease control and prevention.

Summary
Leptospirosis is a significant cause of death in tropical regions of the world. Recent outbreaks in Nicaragua and Brazil are timely reminders of the seriousness of disease caused by the Leptospira bacteria. In these outbreaks >10% of people developing the disease did not recover. Spread of the disease does not occur from person to person, but rather from animal to human.

Recent outbreaks in Nicaragua and Brazil are timely reminders of the seriousness of disease caused by the Leptospira bacteria. In these outbreaks >10% of people developing the disease did not recover. Spread of the disease does not occur from person to person, but rather from animal to human. Leptospira are shed from infected animals via the urine; human infection may occur through contact with infected urine or urine contaminated materials. In Australia, leptospirosis is an occupational hazard with dairy farmers, pig handlers, banana pickers and abattoir workers being those most at risk. A recent and alarming development is the emergence of new risk groups associated with certain leisure activities. For example, in the USA three triathletes died from leptospirosis and it was subsequently determined that the source of infection was contaminated swimming water. This project will investigate aspects of the development of disease and immunity during infection by Leptospira. This will be achieved by analysing the set of proteins located on the surface of the bacterium. These proteins play a key role in the development of disease. Using state of the art technology, each of the proteins will be purified and identified. This will enable experiments that will enhance our understanding of the development of disease at a molecular level.Read moreRead less
A Functional And Structural Approach To Understanding Leptospiral Host-pathogen Interactions

Summary
Leptospirosis is a zoonosis of worldwide distribution caused by infection with pathogenic Leptospira. Infection occurs due to contact with water contaminated by urine of domestic animals. It occurs infrequently in Australia, but recent local surveillance data indicate hospitalisation rate of 56% with an average duration of 5.3 days. Through the combined approach of structural biology and functional microbiology we hope to understand how leptospira interacts with the human host.
