Immersion vaccination of Atlantic salmon ( Salmo salar ) against Yersinia ruckeri
Yersinia ruckeri is a pathogen which causes yersiniosis and significant losses in farmed Atlanticsalmon ( Salmo salar ) in the Southern Hemisphere. Currently, Yersinivac-B, a commercial bacterin-basedvaccine manufactured by MSD Animal Health and prepared from formalin killed whole-cells,is used for...
