Summary
The newly isolated human metapneumovirus (hMPV) causes significant respiratory illness in infants, young children and the elderly. The virus can persist long-term and may predispose individuals to chronic lung disease. This proposal aims to determine the mechanisms by which hMPV infection causes respiratory disease, with a view to improving treatments and preventing disease.

Summary
A newly discovered respiratory virus, human metapneumovirus (HMPV), causes clinical disease that is very similar to human respiratory syncytial virus (RSV) and co-circulates with RSV. Human RSV is a major cause of morbidity and life-threatening respiratory tract disease in infants and young children worldwide, and is recognised as an important respiratory pathogen in elderly adults and immune compromised patients.

Human RSV is a major cause of morbidity and life-threatening respiratory tract disease in infants and young children worldwide, and is recognised as an important respiratory pathogen in elderly adults and immune compromised patients. The recent isolation of HMPV from children hospitalised with respiratory tract illness similar to RSV, but with an unknown etiology, suggests that HMPV may mediate similar clinical pathology. Nothing is currently known about the immune response to HMPV, or the association of these responses with lung disease. The objectives of this proposal are to elucidate the mechanisms of immunity and disease pathogenesis associated with human metapneumovirus (HMPV) and to investigate the use of a novel vaccine to protect against HMPV infection. Once this data is obtained, the study will provide the foundation for further research in the development of vaccines or therapeutic protocols to treat HMPV. It will also provide valuable information for understanding the disease in humans. Also,it is likely that HMPV, like hRSV, may prove to be an agent associated with long-term decreased pulmonary function and airflow limitation perhaps developing to asthma.Read moreRead less
New Insights Into Viral Inflammatory Disease Mechanisms And Approaches To Therapy

Summary
This fellowship aims to establish how viruses cause disease, including how they evade the immune response to persist and cause disease for prolonged periods. My vision is that knowing how the virus and the immune system interact to determine disease severity will assist in devising new treatments and prevention programs to lessen the impact of viral diseases in Australia and worldwide.
RNAi Therapeutic Intervention Of Human Viral Respiratory Disease

Funding Amount

Summary
Human metapneumovirus (HMPV), causes clinical disease that is very similar to human respiratory syncytial virus (RSV) and co-circulates with RSV. HMPV is emerging as a major cause of morbidity and life-threatening respiratory tract disease in infants, young children and the elderly worldwide. No treatment is currently available. The objectives of this proposal are to develop novel antiviral drugs that silence the expression of viral genes and to examine protection against the disease.
Mechanisms Of Induction And Progression Of Childhood Asthma: Investigations In A Mouse Model

Funding Amount
$517,586.00
Summary
This project investigates how certain respiratory viral infections in very young children might predispose to developing asthma, and how inflammation in the airways in asthma might then worsen. The experimental work, which will use unique mouse models developed in the laboratories of the chief investigators, will focus on changes in genes that control the pattern of immune response to allergens and that regulate the progression of inflammation.
White Spot Syndrome Virus (WSSV) Preparedness For Biosecurity Awareness And Adoption Of Best Practice By The NSW And QLD Wild Catch Commercial Fishers - Understanding What Extension Pathways Work Best

Summary
Objectives: 1. Develop appropriate extension material to reduce the risk of spread of WSSV from the control zone to the non control zones in QLD and NSW. 2. To quantify best extension practice for biosecurity for the commercial wild catch fishers. 3. To, where possible, utilise existing extension material developed by Biosecurity Queensland for the commercial wild catch fishery.

Summary
The incidence and severity of infection associated with WRL does not appear to have changed vastly since 1949, despite penicillin therapy and a heightened awareness of the infection by those in the industry. Infection may result in loss of working days. Severe cases may progess to more serious conditions such as septic arthritis and endocarditis, potentially life-threatening conditions.

Infection may result in loss of working days. Severe cases may progess to more serious conditions such as septic arthritis and endocarditis, potentially life-threatening conditions. The inappropriate and unnecessary use of antibiotics is of great concern currently as antibiotic resistant bacteria emerge world-wide. The emphasis is now on preventing infection rather than treating it with antibiotics when it does occur. More advanced techniques for the recovery and detection of E. rhusiopathiae have been developed, including the use of selective media and a molecular method. Further study of these infections, utilising more appropriate techniques, is warranted to determine the exact role that E. rhusiopathiae has in this infection. Also, the role of other organisms causing apparent infection in fishermen of all types needs to be evaluated. This will allow preventive strategies to be developed which will, in turn, result in less infection and reduced exposure to antibiotics. Objectives: 1. To determine the role that E.rhusiopathiae plays in "crayfish poisoning". 2. To determine the distribution of E.rhusiopathiae in the work environment 3. To develop interventions and strategies to reduce the incidence of "crayfish poisoning" Read moreRead less
