Enhanced resistance to coldwater disease following feeding of probiotic bacterial strains to rainbow trout (Oncorhynchus mykiss)

Flavobacterium psychrophilum is the causative agent of coldwater disease (CWD), also called rainbow trout fry syndrome (RTFS), and has a major impact on salmonid aquaculture worldwide. The aim of this study was to evaluate the efficacy of non-pathogenic probiotic bacterial strains to reduce mortality due to F. psychrophilum infection in rainbow trout, (Oncorhynchus mykiss). Candidate probiotics, previously demonstrated to have in vitro...
