About

Australia's foremost aquatic animal disease specialist. Instigated the study of bacteriophage at James Cook University. Most interested in bacteriophage in the Vibrio harveyi clade and viruses of crustacea especially the parvoviruses and the use of RNA interference to combat them. Interested in nodaviruses of fish and crustacea and RNA intererference as a control. Investigating the role of viral UTRs in controlling immunity and diabetes onset.

Development of Preventative Vacing and iRNA to prevent Viral Nervous Necrosis in giant QLD grouper

Indicative Funding
$55,000 over 2 years
Summary
The project will develop and test the effectiveness of a vaccine and dsRNA to prevent the disease Viral Nervous Necrosis in giant groper Epinephalus lanceolatus. Expected outcomes: (1) Collection of genome sequence information on the Betanodavirus strains causing VNN in grouper; (2) Validation of a qPCR which detects and provides a number of viral copies of Betanodavirus; (3) Production of a recombinantly expressed Betanodavirus capsid protein; (4) Production of a Betanodavirus vaccine and dsRNA constructs to prevent VNN disease; (5) Assessment of the effectiveness of the Betanodavirus vaccine and dsRNA constructs in preventing VNN disease.
Investigators
Kelly Condon, Leigh Owens and Terry Miller in collaboration with Adam Reynolds and Richard Knuckey (College of Public Health, Medical & Vet Sciences, College of Science & Engineering and Finfish Enterprise Pty Ltd)
Keywords

Handling Mortality in Redclaw Crayfish (Cherax quadricarinatus) from farms

Indicative Funding
$10,000 (administered by North Queensland Crayfish Farmer)
Summary
Crayfish have become stress-sensitive to handling with low grade mortalities continuing until the crayfish re-acclimate. It is suspected they are carrying so-called orphan viruses. This project will use two independent observational techniques, histopathology and rolling-cycle PCR to look for difficult-to-diagnose viruses. These results will be used to support chapters in the PhD theses of two doctoral students, Shaun Bochow and Kitikarn Sakuna.
