Creator:: Bjork, Sarah J. and Bartholomew, Jerri L.
Abstract:: Ceratomyxa shasta is a myxozoan parasite identified as a contributor to salmon mortality in the Klamath River, USA. The parasite has a complex life cycle involving a freshwater polychaete, Manayunkia speciosa and a salmonid. As part of ongoing research on how environmental parameters influence parasite establishment and replication, we designed...

Predicted Redistribution of Ceratomyxa shasta Genotypes with Salmonid Passage in the Deschutes River, Oregon

Creator:: Stinson, Matthew E. T. and Bartholomew, Jerri L.
Abstract:: Aseries of dams on the Deschutes River, Oregon, act as migration barriers that segregate the river system into upper and lower basins. Proposed fish passage between basins would reunite populations of native potamodromous fish and allow anadromous fish of Deschutes River origin access to the upper basin. We assessed the...

Relationship Between Temperature and Ceratomyxa shasta–Induced Mortality In Klamath River Salmonids

Creator:: Ray, R. Adam, Holt, Richard A., and Bartholomew, Jerri L.
Abstract:: Water temperature influences almost every biological and physiological process of salmon, including disease resistance. In the Klamath River (California), current thermal conditions are considered sub-optimal for juvenile salmon. In addition to borderline temperatures, these fish must contend with the myxozoan parasite Ceratomyxa shasta, a significant cause of juvenile salmonid mortality...

Dam Removal and Implications for Fish Health: Ceratomyxa shasta in the Williamson River, Oregon, USA

Creator:: Hurst, Charlene N., Holt, Richard A., and Bartholomew, Jerri L.
Abstract:: The removal of dams on a river is one potential tool for the ecological restoration of native salmonid fishes. However, the removal of barriers also introduces risks, such as the introduction of fish pathogens into previously isolated populations. The proposed removal of four dams on the Klamath River, Oregon–California, provides...

Effect of Nanophyetus salmincola and Bacterial Co-Infection on Mortality of Juvenile Chinook Salmon

Creator:: Roon, Sean R., Alexander, Julie D., Jacobson, Kym C., and Bartholomew, Jerri L.
Abstract:: The freshwater trematode Nanophyetus salmincola has been demonstrated to impair salmonid immune function and resistance to the marine pathogen Vibrio anguillarum, potentially resulting in ocean mortality. We examined whether infection by the parasite N. salmincola similarly increases mortality of juvenile Chinook Salmon Oncorhynchus tshawytscha when they are exposed to the...

Using Cure Models for Analyzing the Influence of Pathogens on Salmon Survival

Creator:: Ray, R. Adam, Perry, Russell W., Som, Nicholas A., and Bartholomew, Jerri L.
Abstract:: Parasites and pathogens influence the size and stability of wildlife populations, yet many population models ignore the population-level effects of pathogens. Standard survival analysis methods (e.g., accelerated failure time models) are used to assess how survival rates are influenced by disease. However, they assume that each individual is equally susceptible...

Supplemental Description of Myxobolus squamalis (Myxozoa)

Creator:: Polley, Tamsen M., Atkinson, Stephen D., Jones, Gerald R., and Bartholomew, Jerri L.
Abstract:: Abstract: Myxobolus squamalis is a myxozoan skin parasite first reported from rainbow trout (Oncorhynchus mykiss). Identification of the parasite based on myxospore morphology is unreliable because M. squamalis is similar to several other myxobolids that share host species and geographic ranges. The only ssrRNA gene sequence available for M. squamalis...
