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
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
Biotechnology and epidemiology to control nodavirus in barramundi aquaculture. Production of farmed barramundi has increased more than 1200% in the NT since 2001 but is threatened by nodavirus infection. Three industry partners, Darwin Aquaculture Centre, Marine Harvest and Berrimah Veterinary Laboratory will collaborate with The University of Sydney to:
1. control nodavirus infection
2. develop new technologies to detect nodavirus using immunoassay and surface enhanced laser desorption ionis ....Biotechnology and epidemiology to control nodavirus in barramundi aquaculture. Production of farmed barramundi has increased more than 1200% in the NT since 2001 but is threatened by nodavirus infection. Three industry partners, Darwin Aquaculture Centre, Marine Harvest and Berrimah Veterinary Laboratory will collaborate with The University of Sydney to:
1. control nodavirus infection
2. develop new technologies to detect nodavirus using immunoassay and surface enhanced laser desorption ionisation mass spectroscopy (SELDI)
3. develop an integrated disease control strategy based on epidemiological survey data, and ensure that it is practical and able to be widely adopted
By this means growth targets for barramundi aquaculture in northern Australia will be achieved.
