Flea Control by Immunological Intervention. Fleas are bloodsucking parasites that are the major cause of skin disease in pets. Currently, all available flea products rely upon chemical control and many have active components that have real or perceived health problems. Given that insect growth regulators do not kill adult fleas and pet owners are interested in using alternatives to insecticides, there is a clear need for a complementary form of flea control. We describe the novel use of Prote ....Flea Control by Immunological Intervention. Fleas are bloodsucking parasites that are the major cause of skin disease in pets. Currently, all available flea products rely upon chemical control and many have active components that have real or perceived health problems. Given that insect growth regulators do not kill adult fleas and pet owners are interested in using alternatives to insecticides, there is a clear need for a complementary form of flea control. We describe the novel use of Proteomic technology to identify flea proteins that are "switched on" during feeding and are specifically located in the gut. This project will enable the development of a vaccine that is systemic, kills adult fleas, is long-lasting and residue-free.Read moreRead less

Summary
Primary spontaneous pneumothorax (PSP) is a collapsed lung that occurs in otherwise healthy people without underlying lung disease. Current standard treatment is to insert a chest drain into the chest to remove the air around the collapsed lung so that the lung re-inflates rapidly ("interventional treatment"). We will determine whether doing nothing, i.e. letting the lung re-inflate slowly on its own over several weeks ("conservative treatment"), is just as good or even better for patients.
Using Total Population Data To Describe The Characteristics Of Respiratory Infections In Order To Predict Future Epidemics And Recommend Vaccination Strategies For Western Australian Children

Summary
Respiratory infections are a major reason for children to go to hospital. I am an epidemiologist and I will be using previously collected and linked laboratory and hospital data from Western Australian children to better understand how these infections flow through the population over different seasons. I will then be able to predict future epidemics of respiratory infections and how different vaccine programs might have an impact in reducing how many children are affected by these infections.
Understanding the molecular basis of virulence in Brachyspira hyodysenteriae to improve vaccine design. Swine dysentery is a colonic infection of pigs caused by Brachyspira hyodysenteriae. The disease is widespread in Australia and causes great economic loss. An effective vaccine is not available. This study aims to identify factors associated with the bacterium's virulence, using comparative genomic and proteomic information. Virulence factors then will be targeted and tested as recombinant vac ....Understanding the molecular basis of virulence in Brachyspira hyodysenteriae to improve vaccine design. Swine dysentery is a colonic infection of pigs caused by Brachyspira hyodysenteriae. The disease is widespread in Australia and causes great economic loss. An effective vaccine is not available. This study aims to identify factors associated with the bacterium's virulence, using comparative genomic and proteomic information. Virulence factors then will be targeted and tested as recombinant vaccine candidates. This project will result in the development of an improved vaccine to control swine dysentery in rural Australia. Control of swine dysentery through vaccination will reduce antibiotic use on infected farms and improve the productivity and competitiveness of the Australian pig industry.Read moreRead less
Genomic sequencing and comparative genomic analysis for animal bacterial vaccine discovery. The aim of this project is to develop vaccines for the control of swine dysentery (pigs) and intestinal spirochaetosis (pigs and chickens). These infections cause important production-limiting diseases for which no effective vaccines are available. We will use whole genomic sequencing of the two causal species of intestinal spirochaetal bacteria, with a bioinformatics-based analysis of the data to identif ....Genomic sequencing and comparative genomic analysis for animal bacterial vaccine discovery. The aim of this project is to develop vaccines for the control of swine dysentery (pigs) and intestinal spirochaetosis (pigs and chickens). These infections cause important production-limiting diseases for which no effective vaccines are available. We will use whole genomic sequencing of the two causal species of intestinal spirochaetal bacteria, with a bioinformatics-based analysis of the data to identify potential cell surface structures that will be tested as the basis of new recombinant vaccines. Outcomes will include the development of new commercial products, increased institutional capacity in veterinary vaccine discovery, and ultimately improved animal health and production in rural Australia.Read moreRead less
Postviral Wheezing In Childhood: Disregulation Of Airway Tone?

Summary
Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. Ho ....Asthma is a very common childhood condition that is becoming increasingly more common. Wheezing is common in infants and young children following viral infections and is often thought of as the first manifestation of asthma. However, many children and infants who wheeze with viral infections appear to grow out of asthma in their teenage years. Asthma that persists into adult life is usually associated with allergies to common environmental allergens, such as house dust mite and grass pollens. However, many infants who wheeze with viral infections, especially in the first year of life, do not develop allergies in later life, raising the possibility that they did not have the same type of asthma as those whose symptoms persist. This project will study the effects of viral infections on lung function to determine whether particular types of virus can have detrimental effects of lung function lasting for years. We will also examine whether the age at which the infection occurs and the severity of the infection influence the long-term outcome. The project involves studying infants during the recovery phase of respiratory viral infections, older children years after documented infections and experimental animal models that have been infected under controlled conditions. By determining whether respiratory viral infections can have long-term effects on lung function that can mimic asthma, we will advance our understanding of how asthma develops. In addition, specific treatment and preventative strategies could then be developed to prevent these long-term abnormalities, instead of relying on asthma medication (especially inhaled corticosteroids) as is the current practice. Preventative strategies could include encouraging the development of specific vaccines.Read moreRead less
Domestic air quality: towards the setting of guidelines. Air quality standards have been developed to protect human health. Although people spend most of their time indoors there are no standards and only a few guidelines for indoor air pollution (IAP). The aim of this study is to investigate the levels of IAP that may worsen asthma in children. Childhood asthma will be used as a health indicator due to its high prevalence, cost to the healthcare system and implications for respiratory morbidity ....Domestic air quality: towards the setting of guidelines. Air quality standards have been developed to protect human health. Although people spend most of their time indoors there are no standards and only a few guidelines for indoor air pollution (IAP). The aim of this study is to investigate the levels of IAP that may worsen asthma in children. Childhood asthma will be used as a health indicator due to its high prevalence, cost to the healthcare system and implications for respiratory morbidity in adult life. We expect to identify levels of IAP that will represent a health risk as well as the factors that may contribute to increased IAP in homes.Read moreRead less
Rhinovirus impairs physiological and immunological lung development and causes exacerbation of allergic airways disease. Rhinovirus (RV) infections account for around 90 per cent of asthma exacerbations, yet the mechanisms behind this are unknown. This project will use mouse models to study the effects of early life RV infection and allergic sensitisation on respiratory and immunological development, with the expectation that early life RV infection disrupts anitgen presenting cell function.

Summary
Asthma and poor lung function are major causes of public health issues. Emerging evidence suggests adverse exposures even before the conception of a child may cause these conditions. The proposed project is part of an international study across generations to identify these factors. This study will provide novel evidence to guide interventions and identify studies to advance this area further. These original findings will be of great importance both nationally and internationally.
