| 内容記述 | The viability and the pathogenicity of Vibrio anguillarum, the etiological agent of vibriosis in cultured ayu, Plecoglossus altivelis were investigated in the diluted seawater and NaCl solutions of various concentrations prepared by using distilled water and pond water. In 1% seawater the viable cell counts became below 10 cells per m/ within 12 hours but the organisms were able to survive over 30 days at a level of 10' viable cells per ml in 10, 25, 50, and 100% seawater. In the NaCl solutions prepared with distilled water ranging in concentration from 0 to 10,000 ppm, they became undetectable (below 10 viable cells per ml) within 1 minute in 0 and 5 ppm, 10 minutes in 50 ppm, 20 minutes in 500 ppm, 3 days in 5,000 ppm and 15 days in 10,000 ppm. In the pond water they became undetectable within 6 hours, but they were able to survive over 30 days at a level of 102-103 viable cells per ml in 0.2 and 0.85% NaCl-added pond water. The virulence of V. anguillarum to ayu was examined by means of the artificial water-borne challenge, using 0, 0.2 and 0.85% NaCI- added pond water. The per cent of survivors were 50% in the pond water and 20% in 0.2% NaCl-added pond water 10 days after the challenge, and all the fish died in 8 days in 0.85% NaCl-added pond water. These results suggested that V. anguillarum isolated from ayu cultured in freshwater is originated in the seawater, and that the high mortality of the fish is due to the increases in the pathogenicity of V. anguillarum suspended in NaCI solutions of high concentrations and also in the stress caused in the fish by the transfer from freshwater to NaCl-added water. | |||||||||||
