A recently developed in vitro genetic selection technique has allowed the isolation of oligonucleotides that can bind target molecules with high affinity and specificity. The strategy know as SELEX (Systematic Evolution of Ligands by EXponential enrichment) uses protein biochemistry and PCR technology, with subsequent repeated rounds of selection and amplification, to screen vast libraries of oligonucleotides (RNA or DNA) for their ability to bind target proteins. This procedure will be developed by UNSW in collaboration with the biotech company BTF Plc., Ltd., to be used in two applications. The first is the research interest of UNSW and involves the development of aptamers against hepatitis C virus. The second lies within the interests of BTF and will involve the development of aptamers against the water borne pathogen Cryptosporidium parvum.Read moreRead less
Ross River virus - identification of virulence determinants in clinical isolates from across Australia. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. The project has several national benefits. It will elucida ....Ross River virus - identification of virulence determinants in clinical isolates from across Australia. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. The project has several national benefits. It will elucidate whether there is any association between RRV strain and the severity of human disease. It will also identify viral markers that could assist public health officials in determining likely disease outcomes of outbreaks and could provide new avenues for the design of antiviral strategies.Read moreRead less
The multiplexed diagnosis of arbovirus infections using combinatorial probes. Viruses that cause serious diseases such as hemorrhagic fever or encephalitis must be quickly identified. Diagnostic tests based on DNA hybridisation are accurate and can be rapid but they are expensive. We will test a method for simplifying DNA tests and increasing their capabilities. DNA probes for detecting arboviruses will be designed at the ANU using new bioinformatic methods and their reliability will be model ....The multiplexed diagnosis of arbovirus infections using combinatorial probes. Viruses that cause serious diseases such as hemorrhagic fever or encephalitis must be quickly identified. Diagnostic tests based on DNA hybridisation are accurate and can be rapid but they are expensive. We will test a method for simplifying DNA tests and increasing their capabilities. DNA probes for detecting arboviruses will be designed at the ANU using new bioinformatic methods and their reliability will be modelled using all the available genetic information. Computer predictions will be experimentally tested in the PANBIO laboratory by using the probes to detect viral nucleic acids. The influence of virus genome complexity will be investigatedRead moreRead less
Molecular and antibody analysis of cytomegalovirus (CMV) infection of fetal and placental cells. CMV is a beta herpesvirus with many unknown molecular mechanisms associated with cellular infection. The virus infects placental cells in vivo, although pathogenesis of viral damage to these cells has been extremely difficult to study in vitro. We have commenced a study to i) demonstrate the molecular accompaniments of infection of placental cells in vitro, ii) determine the genotypic characteristics ....Molecular and antibody analysis of cytomegalovirus (CMV) infection of fetal and placental cells. CMV is a beta herpesvirus with many unknown molecular mechanisms associated with cellular infection. The virus infects placental cells in vivo, although pathogenesis of viral damage to these cells has been extremely difficult to study in vitro. We have commenced a study to i) demonstrate the molecular accompaniments of infection of placental cells in vitro, ii) determine the genotypic characteristics of congenital CMV infections, in collaboration with Abbott Diagnostics, and iii) produce an in vivo model of CMV infection to demonstrate the pathogenesis of cellular injury. The combination of molecular expertise at UNSW with monoclonal antibody expertise from Abbott Diagnostics mean this project is unique worldwide.Read moreRead less
A comparative study of the distribution and spread of potential molecular markers for Mundulla Yellows disease. Mundulla Yellows (MY), a newly recognised widespread lethal disease of Eucalyptus spp.in Australia, is a serious threat to national biodiversity and conservation. It is contagious, apparently biotic, but the causal agent is unknown. Identification of the cause is essential to establish sustainable control measures. We have detected a range of MY-associated RNAs constituting a disease ' ....A comparative study of the distribution and spread of potential molecular markers for Mundulla Yellows disease. Mundulla Yellows (MY), a newly recognised widespread lethal disease of Eucalyptus spp.in Australia, is a serious threat to national biodiversity and conservation. It is contagious, apparently biotic, but the causal agent is unknown. Identification of the cause is essential to establish sustainable control measures. We have detected a range of MY-associated RNAs constituting a disease 'fingerprint'. To identify individual RNAs uniquely associated with MY we aim to compare MY-RNA fingerprints from a range of affected species from different sites and with varying symptoms. Candidate RNAs will be cloned both for establishing molecular diagnostics for MY and identifying the cause.Read moreRead less
Development of purified antibodies that kill virus infected cells. This proposal will develop panels of purified and monoclonal antibodies that kill virus infected cells. These antibodies may show efficacy in preventing HIV infection. This is new technology that could subsequently be harnessed to protect or limit the devastating effects of chronic viruses such as HIV.

The project addresses a common disease problem, influenza, with a novel application of antibody technology. The technology may safely provide protection and cost effective treatment for those members of the community who are least protected by current approaches. The product can be cost-effective and readily available to enable the public to self medicate in high risk situations, or to be used as a public health tool in situtions to control outbreaks in those most susceptible to serious disease. The production system that enabled the creation of the technology is the advanced Australian dairy industry. Farmers with herds participating will receive a significant income benefit from, what was before, largely a waste product.Read moreRead less
