  Salmonid species in the Laurentian Great Lakes basin suffer from early mortalities that are often associated with low survival rates of swim-up fry. Coho salmon (Oncorhynchus kisutch) alevins exhibiting a spinning swimming behavior and convulsions were presented to the Aquatic Animal Health Laboratory of Michigan State University. Twelve yellow-pigmented bacterial isolates that were motile via gliding were recovered from the brains of dead and moribund fish and identified as Flavobacterium spp. (designated CS: 29-31, 34-38, 40-43). 16S rRNA sequence analysis indicated that 9 of the 12 sequences were grouped into a single clade (CS29, 31, 34-38, 40, 41) and were essentially identical over the 676 aligned bases used in the phylogenetic analysis. This clade is closely related to the eel-pathogenic Flavobacterium johnsoniae-like YO60 recovered from South .. View More»
