MOSCOW, Idaho – University of Idaho fisheries scientist Ken Cain and Washington State University researcher Douglas Call have collaborated to develop an antibody that detects the fish pathogen that causes Coldwater Disease in trout and salmon.
A new licensing agreement between the University of Idaho and ImmunoPrecise Antibodies Ltd. (IPA), a company that produces antibodies to many salmonid pathogens, will commercialize an important antibody for screening the aquatic pathogen Flavobacterium psychrophilum in salmon and trout broodstock. The pathogen causes bacterial Coldwater Disease in North America and Rainbow Trout Fry Syndrome in Europe and Japan.
“The whole idea is for fish labs to be able to use this antibody to rank levels of infection in adult fish and determine the liklihood of transferring the infection to their progeny,” said Cain, associate director of the University of Idaho Aquaculture Research Institute.
Coldwater Disease is a worldwide problem for rainbow trout reared in fish hatcheries for commercial aquaculture and resource enhancement. In recent years, economic losses from this disease in Idaho’s trout industry alone are estimated at approximately $10 million annually, and in the U.S. only a limited number of therapeutic treatments are available to combat its devastating effects.
Up to this point, diagnostic labs have primarily detected Flavobacterium psychrophilum, the pathogen that causes Coldwater Disease, using a time consuming culturing process. IPA will work with Cain’s laboratory, along with other researchers, to develop a diagnostic kit for quantifying infection levels in commercial hatcheries.
There are two assays, or protocols that have been developed: one that quantifies the level of infection in fish, and one that binds the antibody to the pathogen with a fluorescent tag that can be visualized easily under the microscope. Each assay makes it easier to detect and cull infected fish.
IPA will have purified anti-F. psychrophilum monoclonal antibody available for sale by August 2009. Diagnostic kits will be available by early 2010. Contact IPA at (250) 483-0308 for more information.
