TOXICITY TEST AND HALF LETHAL CONCENTRATION OF VIBRIO ANGUILLARUM TO THE CLAM CYCLINA SINENSIS
鳗弧菌(Vibrio anguillarum)对青蛤(Cyclina sinensis)的毒性及半致死浓度研究

The acute toxicity test was conducted under different concentration of Vibrio anguillarum to Cyclina sinensis. The death rate of the C. sinensis were observed, then the half lethal concentration of V. anguillarum was got after infection. The results showed that the death rate of the clam was increased at the Vibrio concentration from OD600= 1.0 to OD600= 2.2 in 96h, and all the experimental individuals were dead at the concentration OD600= 2.2. The death rate and the Vibrio concentration showed a positive correlation at the same time point. After analyzing the experimental data by SPSS 16 package, we got that the LC50 of Vibrio anguillarum to C. sinensis was OD600= 1.57. The results suggested that the V. anguillarum was obviously toxic to C. sinensis.
