Fig 2. Comparison of the mortality of rainbow trout challenged with the parental virus and the passaged virus.

The challenges were performed at 1 week post-vaccination (A) and at 6 weeks post-vaccination (B). White bars correspond to non-vaccinated fish and black bars correspond to fish vaccinated with the DNA vaccine. The mortality values of the vaccinated fish infected with the passaged and the parental virus at either 1 or 6 weeks post-vaccination were not statistically significant different. The mortality values of the non-vaccinated and the vaccinated fish challenged at either 1 or 6 weeks post-vaccination were statistically significant different (p<0,005).
