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...
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...

We investigated intra-specific variation in the response of salmon to infection with the
myxozoan Ceratomyxa shasta by comparing the progress of parasite infection and measures of
host immune response in susceptible and resistant Chinook salmon Oncorhynchus tshawytscha at
days 12, 25 and 90 post exposure. There were no differences in...
