What Makes a Fish Resistant? Comparative Genomics and Transcriptomics of Oncorhynchus mykiss with Differential Resistance to the Parasite Ceratonova shasta

Creator:

Barrett, Damien E.

Abstract:

The myxozoan Ceratonova shasta is an intestinal parasite of salmon and trout that causes ceratomyxosis, a disease characterized by severe inflammation of the intestine that can lead to hemorrhaging, necrosis, and death of the fish host. The parasite is endemic to the Pacific Northwest of the United States and Canada,...

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...
