  • 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...

  • 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....

  • 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....

  • Ceratomyxa shasta-related concerns for reintroduced anadromous salmonids into the Upper Klamath Basin, CA-OR, USA

    Creator:
    Hurst, Charlene N.
    Abstract:
    The myxozoan parasite of salmonids, Ceratomyxa shasta, is established throughout the Klamath River, CA-OR, with high parasite densities below the series of dams and above the dams (upper basin) in the northernmost tributary, the Williamson River (WMR). Two objectives were designed to address concerns about C. shasta effects on reintroduced...

  • Re-examining Ceratomyxa shasta in the Pacific Northwest

    Creator:
    Stinson, Matthew E. T.
    Abstract:
    Ceratomyxa shasta infects salmonids in the Pacific Northwest (PNW) of North America, occasionally causing losses in wild and captive populations. Host-specific parasite genotypes (O, I, II, III) were previously characterized molecularly using markers in the ribosomal DNA and phenotypically by type host in the Klamath River, CA/OR. This thesis sough...

  • The Role of the Mucosal Immunoglobulin IgT and Inflammatory Cytokines in Ceratonova shasta Infections in Rainbow Trout

    Creator:
    Taggart-Murphy, Laura M.
    Abstract:
    The myxozoan parasite Ceratonova shasta threatens both juvenile and adult salmonid populations in the Pacific Northwest region of the United States, causing intestine necrosis and hemorrhaging, along with high mortality in some fish strains. It induces an inflammatory tissue response in susceptible strains of fish; understanding the interactions between C....
