Summary
Chlamydia is a common sexually transmitted infection (STI) caused by the bacterium, Chlamydia trachomatis (CT). Annually, 50 million new cases of chlamydia are estimated to occur worldwide which if untreated, can lead to serious complications such as pelvic inflammatory disease and infertility in women and epididymitis in men. Over the past decade, there has been a sharp increase in diagnoses of chlamydia in Australia, coinciding with a reported upsurge in sexual risk behaviour (increased partne ....Chlamydia is a common sexually transmitted infection (STI) caused by the bacterium, Chlamydia trachomatis (CT). Annually, 50 million new cases of chlamydia are estimated to occur worldwide which if untreated, can lead to serious complications such as pelvic inflammatory disease and infertility in women and epididymitis in men. Over the past decade, there has been a sharp increase in diagnoses of chlamydia in Australia, coinciding with a reported upsurge in sexual risk behaviour (increased partner numbers and-or practices of unprotected sex), particularly among men who have sex with men (MSM). In addition, there are current outbreaks of an invasive CT strain, causing lymphogranuloma venereum (LGV), throughout Western Europe, with cases now reported in the USA. LGV can lead to severe anogenital ulcers, which can increase transmission of HIV, hepatitis C, and other STIs. With growing international travel, the likelihood of LGV outbreaks in Australia, particularly in MSM, is increased. Recently, isolated cases of LGV have been noted in MSM attending Sydney and Melbourne Sexual Health Centres, indicating LGV is possibly already in circulation. Since we know little about circulating CT types in Australia it would be difficult to assess the burden of an LGV outbreak. Due to increasing CT infections and likely risk of increased HIV transmission, particularly with LGV strains, surveillance of CT genotypes in Australia, especially in MSM, is important. The purpose of this study is to type CT strains in our population by looking at their genetic makeup. CT-positive specimens from Melbourne and Sydney will be used to identify CT types in circulation and to assess if LGV types are present. The knowledge obtained from this study will be novel and invaluable, and could contribute considerably to the development of improved disease prevention and intervention strategies, including the design of vaccines.Read moreRead less
Energy-Efficient Communication Protocols for Wearable Wireless Biomedical Sensor Devices. The communication protocols developed in this project will directly contribute to the realisation of wearable, mobile, and robust devices for continuous medical monitoring.

The communication protocols developed in this project will directly contribute to the realisation of wearable, mobile, and robust devices for continuous medical monitoring. Several Australian industries can benefit economically by using the technology to improve the performance, efficiency, and longevity of their existing systems for chronic disease management, aged care, personal wellness, occupational health, and in hospitals/GPs. Non-intrusive monitoring offers quality-of-life to the millions of aged and chronically ill Australians, while low-cost allows it to be widely used in regional and rural communities. Partaking in the innovation of the technology will also give Australia a strong position in the ICT space.Read moreRead less

Australia's population is ageing, with a significant, projected increase in the number of people aged over 65. This project addresses the core issue of providing an end-to-end assistive healthcare loop to maintain the wellness as well as improving the quality of life of this ageing population. It promises to reduce the enormous cost of public and primary healthcare. Furthermore, with the proposed framework, an end user will be able to enjoy the support of multiple caregivers (relatives, community-caregivers, etc.) working collaboratively. These factors certainly relate this project to the strengthening of Australia's social and economic fabric priority.Read moreRead less
Can Skin Infection With Group A Streptococcus Cause Acute Rheumatic Fever?

Summary
It is traditionally taught that the cause of acute rheumatic fever (ARF) is always infection of the throat with the bacterium group A streptococcus (GAS). However, in Aboriginal communities of the Top End of the Northern Territory the incidence of ARF is the highest reported in the world, yet GAS is uncommonly isolated from the throat. There is further information to suggest that GAS skin sores may underlie many cases of ARF. If this were proven, it would completely alter the traditional view of ....It is traditionally taught that the cause of acute rheumatic fever (ARF) is always infection of the throat with the bacterium group A streptococcus (GAS). However, in Aboriginal communities of the Top End of the Northern Territory the incidence of ARF is the highest reported in the world, yet GAS is uncommonly isolated from the throat. There is further information to suggest that GAS skin sores may underlie many cases of ARF. If this were proven, it would completely alter the traditional view of the cause of ARF, and have important implications for prevention of ARF around the world. Presently, these approaches focus on diagnosing and treating sore throat, but no country has proven that such a program can be successful in substantially reducing new cases of ARF. If it was known that skin infection could lead to ARF, then countries (including Australia) could emphasise the importance of skin health programs. A further benefit of this knowledge would be to influence GAS vaccine development, which presently is largely focused on the prevention of sore throat. A different possibility has recently been raised - that the cause of ARF may not always be GAS, but instead that the related bacteria GCS and GGS may have the potential to cause this disease. Proof of this hypothesis would even more dramatically alter our understanding of disease causation, prevention, and vaccine development. We propose to determine the cause of ARF in Aboriginal communities by regularly swabbing families of people with a history of ARF, and using genetic fingerprinting of the bacteria from the skin and throat swabs. When cases of ARF occur, we will be able to determine the site and type of infection that precipitated the attack. We will conduct a related study in more communities, in which we will swab family members of people with ARF and of control families (without ARF) to determine the bacteria most commonly isolated from ARF families.Read moreRead less

AIV has the potential to devastate the poultry industry and cause human pandemics, but the factors that shape the genetic diversity of AIV in its wild bird reservoir are poorly understood. The project plans to combine genomic, ecological and phylogenetic approaches to reveal key aspects of AIV evolution, as well as the risk for future viral emergence. Using sampling sites in Australia and Antarctica, it plans to investigate AIV diversity, the evolutionary dynamics of AIV in wild birds and poultry, and the role played by environmental transmission in AIV ecology.Read moreRead less

Summary
Medicines have an important place in health and are commonly used for long periods, sometimes life-long. Using medicines wisely requires a careful balance between benefits and harmful effects. Currently, there is limited information to guide medicines use over a lifetime. Using large linked datasets, the CRE in Medicines and Ageing will generate much needed evidence about real world medicines use to support clinical and pharmaceutical policy decisions.
Understanding mutation and genetic reassortment in viruses: new mathematical models of viral dynamics and evolution. This project aims to understand how evolutionary processes and ecological conditions combine to ignite and sustain viral epidemics. Using novel mathematical models and statistical methods we will study the manner in which viral genes mutate and are recombined, as well as the rates of these important forces.

The project expects to create a new framework for forecasting the evolution of solar active regions, applying, for the first time, methods established in Numerical Weather Prediction. The expected outcomes are physics-based prediction of solar atmospheric magnetic field evolution, including explosive eruptions. The results should have significant benefit in improving prediction of extreme space weather events, which pose an increasing threat to our technologically-dependent society.Read moreRead less
