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...
In mammals, CCR7 is the chemokine receptor for the CCL19 and CCL21 chemokines, molecules with a major role in the recruitment of lymphocytes to lymph nodes and Peyer´s patches in the intestinal mucosa, especially naïve T lymphocytes. In the current work, we have identified a CCR7 homologue in rainbow trout...
More than six million American students have a diagnosed disability (NCES, 2015). Research suggests that 62% of them may never participate in clubs, sports, or other organized activities in their communities (Coster et al., 2012). Parents, advocates, and educators of individuals who experience disability were interviewed to gather their perspectives...
Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...
The purpose of this study is to identify firm safety practices, safety technologies, and firm characteristics that are related to motor carrier accident rates. The theory of the firm suggests that firms maximize profit by investing in safety practices and safety technologies until marginal cost is equal to the marginal...
