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
Detection of imported exotic strains of West Nile virus for national biosecurity surveillance. West Nile virus (WNV) is transmitted by mosquitoes and causes a fatal disease of the brain in animals and humans. WNV is currently exotic to this country, however a closely related, but benign cousin of this virus (Kunjin) can be found in Northern Australia. Currently it is very difficult to differentiate between infections with WNV and Kunjin using standard laboratory tests, therefore it will be diff ....Detection of imported exotic strains of West Nile virus for national biosecurity surveillance. West Nile virus (WNV) is transmitted by mosquitoes and causes a fatal disease of the brain in animals and humans. WNV is currently exotic to this country, however a closely related, but benign cousin of this virus (Kunjin) can be found in Northern Australia. Currently it is very difficult to differentiate between infections with WNV and Kunjin using standard laboratory tests, therefore it will be difficult for public health officials to detect WNV if it is introduced to Australia. In this project we aim to develop more accurate laboratory tests to detect infections with the deadly, exotic WNV using new strategies. Read 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

Infection with Cyclospora cayetanensis is an emerging disease that causes significant morbidity in human populations. Although prevalent in developing countries, recent outbreaks in the USA confirm it is now emerging into the developed world. The research described here will analyse and characterise the antigens on the surface of the oocyst of C. cayetanensis which will add significantly to our sparse knowledge on this important human parasite. We will also develop the first commercial antibodies and technologies which will rapidly and accurately detect the parasite in human patients and our drinking water supplies, thus securing a global market for Australian technology.Read moreRead less

Negative strand viruses (NSVs) include diverse animal pathogens that represent significant threats to Australian livestock industries and access to export markets. The project aims to investigate the interface formed by NSVs with cellular nucleoli in order to determine roles in viral manipulation of cell biology during infection. This project hopes to address a major gap in knowledge in virology regarding the fundamental biology of NSVs, and is expected to redefine our understanding of the virus-host interactions formed by these important pathogens. By determining the mechanisms of NSV-nucleolus interaction, the project plans to also provide important information for the development of new vaccines/therapeutics for livestock to combat NSVs that target nucleoli.Read moreRead less

This project aims to identify how microbial communities, known as microbiomes, can be effectively manipulated to the benefit of their host. Microbiome manipulation has been in the spotlight as a potential solution to maintain or improve the health of several hosts, from threatened coral species to livestock and humans, but the development of industry-scale strategies has been slow. This project proposes to chart the nutritional interactions among microorganisms and to identify cascade effects of microbiome manipulation. This will generate fundamental knowledge on the biological processes underlying community stability and malleability, which will ultimately help engineering optimised microbiomes.Read moreRead less
