A study of Myxobolus cerebralis in the Lostine River, Oregon : epizootiology, distribution and implications for resident and anadromous salmonids

Creator:

Sandell, Todd A.

Abstract:

Myxobolus cerebralis, a myxozoan parasite that infects almost all species of wild and cultured salmonids, was first identified in northeastern Oregon in the Lostine River in 1986. Fish that are heavily infected with M. cerebralis develop whirling disease, which was determined to be the cause of catastrophic declines in rainbow...

Assessing disease impacts of hatcheries on downstream salmonids in the Willamette River Basin, Oregon

Creator:

Jakaitis, Michelle

Abstract:

Hatcheries are often perceived as a source of pathogen amplification, potentially increasing disease risk to free-ranging populations; at the same time, free-ranging fishes may introduce pathogens into hatcheries through untreated water sources. Many pathogens exist naturally within the environment (with the exception of introduced pathogens) and the presence of a...

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...

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...

Distribution and coinfection of microparasites and macroparasites in juvenile salmonids in three upper Willamette River tributaries

Creator:

Roon, Sean Robert

Abstract:

Wild fish populations are typically infected with a variety of micro- and macroparasites that may affect fitness and survival, however, there is little published information on parasite distribution in wild juvenile salmonids in three upper tributaries of the Willamette River, OR. The objectives of this survey were to document (1)...

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...

Ecology and applications of cutaneous mechanisms of resistance to amphibian chytridiomycosis

Creator:

Nebergall, Emily E.

Abstract:

Amphibian biodiversity is in rapid global decline, due in part to the fungal disease chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd). Susceptibility to Bd and chytridiomycosis varies between species and populations. Skin peptides and symbiotic skin bacteria appear to be important mechanisms of Bd resistance. However, not much is known about...

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...

Hydraulic predictors and seasonal distribution of Manayunkia speciosa density in the Klamath River, CA, with implications for ceratomyxosis, a disease of salmon and trout

Creator:

Jordan, Michelle S.

Abstract:

The freshwater polychaete Manayunkia speciosa was identified as an obligate host of the salmonid parasite Ceratomyxa shasta in 1997, prompting increased research on the small benthic invertebrate. Ceratomyxa shasta infection in fish can cause mortality, and presents a disease risk for both hatchery and wild salmon and trout. Ceratomyxa shasta...

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;...
