Influence of "Aging" on the maturation, examined by scanning electron microscopy, and transmission of Ceratomyxa shasta (Myxosporea), a protozoan parasite of salmonid fishes

Occurrence of the protozoan parasite Ceratomyxa shasta among salmonid fishes in Oregon waters

Creator:: Sanders, James Edward
Abstract:: This project was initiated to determine the incidence, distribution and species of fish affected by Ceratomyxa shasta in Oregon waters. Returning adult Pacific salmon and steelhead trout were chosen for the survey because they were known to be susceptible to infection. The parasite was also believed to be an important...

Occurrence of the protozoan fish parasite Ceratomyxa shasta in the Deschutes River basin and the ultrastructure of the spore

Creator:: Gould, Rowan Wayne
Abstract:: The purpose of this paper was twofold, (1) to determine the distribution of the infective stage of Ceratomyxa shasta (Noble) in the Deschutes River basin, and (2) to study the ultrastructure of the spore stage of the protozoan parasite. Liveboxes containing juvenile rainbow trout were placed at specific test points...

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....

Factors affecting the Ceratomyxa shasta infectious cycle and transmission between polychaete and salmonid hosts

Creator:: Bjork, Sarah J.
Abstract:: Ceratomyxa shasta is a myxozoan parasite that infects salmonid fishes causing the disease ceratomyxosis that is characterized by severe hemorrhage and necrosis of the intestine and death of the fish host. Ceratomyxa shasta is endemic to the Pacific Northwestern United States and Canada, where epizootics are reported for both wild...

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;...

Climate warming effects on the life cycle of the parasite Ceratomyxa shasta in salmon of the Pacific Northwest

Creator:: Chiaramonte, Luciano V.
Abstract:: Aquatic ecosystems continue to be increasingly affected by climate warming. For salmonids in the Pacific Northwest of North America, increasing temperatures pose tighter thermal constraints on their habitat use as well as aspects of their individual performance, such as disease resistance. This thesis examines the effect of temperature on the...

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 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...
