Vaccine development for rainbow trout fry syndrome (RTFS) has been based primarily on whole-cell bacterins. In this study, protective effects of candidate strain to develop a vaccine in future studies against to Flavobacterium psychrophilum were investigated. Alteration in the relative percentage of survival rate (RPS) of rainbow trout exposed to 1×108 CFU/mL formalin-killed cells for 30, 60 and 90 min. Upon challenge with a strain the RPS of respectively, 21.74%, 34.78% and 43.48% was recorded. The results suggested that a weak protection had obtained with this strain, therefore; the strain was not suitable for use in vaccine development.
