Parenteral and oral vaccination were made against furunculosis of native trouts. In the case of parenteral vaccines, 0.1 mg of formalin killed cells suspended in saline were injected intraperitoneally. The survival rate at the end of experiment was higher in the vaccinated group than in the control group. Agglutination titer was reached higher than 1, 000 and had maintained for long time in adjuvant vaccine group.<BR>Another experiment was done with fingerings of native trouts fed to 0.15 or 0.3 mg of vaccine per fish a day. Efficacy of oral vaccine was compared with both mortality and challenge test of intramuscular injection or bacterial bathing. The mortality due to furunculosis was higher in the control group than in the vaccinated group.
