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.

AgriFutures Australia - Research Grant

Viral Causes of Crayfish Handling Mortalities

Indicative Funding
$20,000 over 2 years (administered by North Queensland Crayfish Farmers Assn)
Summary
Northern Queensland crayfish from farms affected by stress, particularly transportation stress, started to die with mortality reaching 20-40% after about three weeks. Two new viruses were found, Cheque iflavirus and Athtab Bunya-like virus. This research will determine the infection cycle of the viruses to understand how to intervene and control the impact of these viruses.
Investigators
Leigh Owens, Jennifer Elliman and Kitikarn Sakuna in collaboration with Colin Valverde (College of Public Health, Medical & Vet Sciences and North Queensland Crayfish Farmer's Association)
Keywords
Redclaw Crayfish; Iflavirus; Bunya-like virus; Parastacidae; Cherax quadricarinatus; RNA Interference

FinFish Enterprise Pty Ltd - Contract Research

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
Epinephalus lanceolatus; family Serranidae
