FIG. 5.

Survival rates of carp infected by the FL BAC 136 LUC TK revertant strain. On day zero, two groups of fish, each consisting of 10 common carp kept in separate tanks, were infected by bathing them with FL and FL BAC 136 LUC TK revertant strains as described in Materials and Methods. The fish were examined daily for clinical signs of KHV disease, and dead fish were removed. The percentage of survival is expressed according to days p.i. The results presented are representative of three independent experiments.
