Summary
Scabies is a common skin disease in developing countries, in particular in the Pacific region. In the Western Province of Solomon Islands, one in two children suffer from the infestation, and 20% of the population. We know that mass drug administration with two doses of oral ivermectin is effective to reduce the burden of scabies in the community. We now propose a study to determine whether one single dose is as effective. This would have major public health benefits.

Summary
Scabies is common skin disease in developing countries, in particular in the Pacific region. In Fiji, one in two children suffer from the infestation, which affects over 20% of the population. A recent study conducted in Fiji on 2000 people showed that mass drug administration (MDA) with oral ivermectin is a safe and effective way to reduce the burden of scabies in the community. We will expand the MDA program to 100,000 people, the largest study of MDA ivermectin for scabies ever undertaken.
Horizontal And Vertical Transmission Mechanisms Of Staphylococcus Aureus Multiresistance Plasmids

Summary
Strains of Golden Staph bacteria resistant to many antibiotics are a major cause of serious hospital-acquired, and increasingly community-acquired, infections. The bacteria have mechanisms that cause efficient transmission of resistance genes to their offspring as well as to other strains. This project aims to elucidate key features of these mechanisms so that treatments can be devised that disrupt the maintenance and transfer of resistance, so as to prolong the effectiveness of antibiotics.
The Interplay Between Viperin, Peroxisomes And The Cellular Innate Antiviral Response

Summary
Infection with a virus initiates a cellular antiviral response that attempts to limit viral replication, however how this response is regulated is not well understood. In this proposal we will investigate a cellular protein (viperin) that can regulate this process by interaction with peroxisomes to amplify the antiviral response. This work will provide possible targets for therapeutic manipulation of the innate immune response that will be applicable to a wide range of viral infections.

Summary
Meningitis and brain infection (meningoencephalitis) due to the fungus Cryptococcus, affect over 1 million patients with AIDS annually, especially in developing countries; with more than 600,000 deaths. It is not known how Cryptococci cross from the blood stream into the brain; this must be elucidated in order to prevent and/or control this devastating infection. This project will determine how cryptococci influence host blood cells to act as “Trojan horses” and/or release products that initiate ....Meningitis and brain infection (meningoencephalitis) due to the fungus Cryptococcus, affect over 1 million patients with AIDS annually, especially in developing countries; with more than 600,000 deaths.

This project will determine how cryptococci influence host blood cells to act as “Trojan horses” and/or release products that initiate invasion of brain tissue and meningitis.Read moreRead less
Resolving Human Immunodeficiency Virus (HIV) Transmission

Summary
To increase the breadth of HIV prevention strategies, it is imperative that we biologically understand how HIV enters our bodies. Through two unique clinical cohorts, we will determine why circumcision is protective and how a commonly acquired sexual transmitted infection (human papilloma virus) can increase HIV transmission.
Mosquito-borne alphaviruses such as Ross River and chikungunya viruses cause widespread epidemics and exert extreme pressure on the public health systems of affected regions. Alphaviruses spreads to joints and triggers a severe disease in those affected. There are no effective treatments or vaccines. The project will investigate virus-host interaction at the bite site. The outcome will be new knowledge to treat infection at the mosquito bite site to prevent joint disease.

Summary
Infections with mosquito-borne viruses are increasing at an alarming rate worldwide. Ross River virus is endemic in parts of Australia, PNG and Pacific islands, while chikungunya virus is distributed globally and causes recurrent pandemics that involve millions of people. These viruses cause severe musculoskeletal disease for several months after infection. This project aims to establish how these viruses interact with the human host to cause disease and may provide a basis for new treatments.

Summary
Hepatitis C virus (HCV) is a serious viral pathogen that causes significant liver disease. This proposal plans to examine how two proteins from the HCV, core and NS5A, interact with host proteins and pathways to facilitate viral replication and release of HCV; two processes that are poorly understood. Specifically we will tag viral proteins to allow us to investigate the HCV life cycle in living cells and determine the role of core and NS5A in facilitating HCV replication.

Signalling Pathways And Fungal Virulence – The Inositol Polyphosphate Kinase Pathway In Cryptococcus Neoformans

Summary
Bloodstream fungal infections kill millions of people per year world-wide and are costly to treat. A potentially fruitful strategy for developing new, urgently-needed drugs to fight these infections, is to target signalling pathways, which in fungi, are essential for establishing infection. This proposal investigates how one such pathway, the inositolpolyphosphate kinase pathway, allows fungi to establish infection and will determine which components are suitable targets for drug development.
