Development of monoclonal antibodies against the myxosporean, ceratomyxa shasta, and characterization of the salmonid host response

Creator:: Bartholomew, Jerri Lee
Abstract:: Monoclonal antibodies (Mabs) were produced against the myxosporean parasite, Ceratomyxa shasta, and were characterized by indirect immunofluorescent techniques, western blot analysis, and immunoelectron microscopy. The resulting Mabs reacted specifically with the trophozoite and sporoblast stages of the parasite, but not with the mature spore, indicating that certain antigens are stage-specific....

Deschutes River Salmonid Risk of Enteronecrosis in a Changing Climate

Creator:: Yusova, Sofiya
Abstract:: Ceratonova shasta is an obligate endoparasite of salmonid fish that is endemic to the Pacific Northwest of North America. The parasite has a complicated lifecycle with two distinct spore stages and two obligate hosts, a salmonid and a freshwater annelid. Myxospores released from infected salmonid hosts, infect Manayunkia occidentalis (freshwater...

The ecology of parasite interactions within Chinook salmon

Creator:: Hurst, Charlene N.
Abstract:: The within-host interactions that can occur as a result of mixed infections in wildlife likely influence the outcome of an infection. We investigated the infection frequency and outcome as well as the potential mechanisms regulating mixed infections with two Ceratonova shasta genotypes within the Chinook salmon host. Previous research in...

Modeling abiotic influences on disease dynamics for the complex life cycle of the myxozoan parasite Ceratomyxa shasta

Creator:: Ray, Robert Adam
Abstract:: Most parasites and their hosts live in a balance within their environment; however a disease outbreak can occur when either the parasite, host, or environment, are perturbed. Myxozoan parasites are associated with a wide variety of cultured and wild fish populations. Most myxozoans are relatively benign to their vertebrate host;...

Distribution of Ceratomyxa shasta (Myxozoa) and habitat preference of the polychaete host, Manayunkia speciosa in the Klamath River

Creator:: Stocking, Richard W.
Abstract:: Ceratomyxa shasta is a myxozoan parasite of salmonids and requires the freshwater polychaete, Manayunkia speciosa to complete its life cycle. The parasite’s distribution is currently limited to the Pacific Northwest region of North America and has been reported to cause substantial losses of both wild and hatchery salmonids. The spatial...

Spatiotemporal Distribution of Ceratonova shasta and its Genotypes in the Deschutes River Basin

Creator:: Hubbard, Kalyn M.
Abstract:: The waterborne, myxozoan parasite Ceratonova shasta is endemic to the Pacific Northwest and can be lethal to its secondary salmonid host, including the culturally, economically, and recreationally important spring Chinook salmon (Oncorhynchus tshawytscha) of the Deschutes River, OR. Previously described genotypes of C. shasta exhibit specificity with their salmonid hosts....

Bacteriophages Significantly Reduce Mortality of Larval Pacific Oysters Crassostrea gigas from Infection by the Pathogenic Bacterium Vibrio coralliilyticus RE98

Creator:: Madison, David B.
Abstract:: Vibrio coralliilyticus (Vcor) is a bacterial pathogen that is well adapted to shellfish hatcheries and is very pathogenic to the larvae of the Pacific oyster Crassostrea gigas. Vcor has been associated with several large scale larval mortality events in the Pacific Northwest that interrupt the supply of seed oysters available...

The effects of single and multiple pathogen and parasite infections on juvenile chinook and coho salmon during early marine residency

Creator:: Sandell, Todd A.
Abstract:: Nearly 3000 juvenile Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon captured in nearshore waters off the coasts of Washington and Oregon from 1999-2004 were tested for infection by Renibacterium salmoninarum, Nanophyetus salmincola, and skin metacercariae. First, three quantitative PCR primer/probe sets were compared for detection of R. salmoninarum; amplification...

Molecular Analysis of Environmental Water Samples as a Monitoring Method for the Fish Parasite Ichthyophthirius multifiliis

Creator:: Howell, Claire K.
Abstract:: Parasites are ubiquitous members of ecological communities, capable of contributing to the decline of vulnerable populations. Therefore, monitoring parasite level is a critical component for host management. Molecular tools, such as quantitative polymerase chain reaction (qPCR), can be valuable additions to monitoring protocols that assess parasitic disease risk to hosts....
