Fig 7. Strain 4466 provides full protection to gnotobiotic rainbow trout larvae against infection by four strains of F. columnare.

Fig 7

Flavobacterium sp. Survival of GF trout larvae exposed to Flavobacterium sp. strain 4466 48 h before infection with F. columnare strains Fc7, IA-S-4, Ms-Fc-4 and ALG-00-530. All F. columnare strains rapidly killed GF fish, whereas trout larvae that were re-conventionalized with Flavobacterium sp strain 4466 survived to all strains of F. columnare. Mean and SD plot representing average day post-infection at which infected fish died. For each condition n = 10 larvae. All surviving fish were euthanized at day 10. Asterisks indicate significant difference from non-infected population (****p<0.0001).
