摘　　要：试验探究了臭氧在体外对代表性盾纤毛虫病原海洋尾丝虫(Uronema marinum)的杀灭效果。试验通过向人工海水通入不同时间的臭氧获得不同浓度的臭氧海水,并对海洋尾丝虫进行杀灭。结果显示,盐度30‰、臭氧浓度0.54 mg/L的海水溶液可完全杀灭20000 ind/mL的海洋尾丝虫;盐度20‰、25‰、30‰的海水通入10 min臭氧后,水体臭氧浓度均>0.80 mg/L,可完全杀灭环境中海洋尾丝虫;盐度15‰海水通入10 min臭氧后,臭氧浓度可达到0.54 mg/L,可完全杀灭环境中海洋尾丝虫。研究表明,臭氧对海洋尾丝虫具有明显的杀灭作用,试验结果为后续开展盾纤毛虫病的绿色防控技术研究提供了参考。The killing effect of ozone in vitro against the representative Scuticociliates pathogen Uronema marinum was investigated.In the experiment,different concentrations of ozone seawater were obtained by injecting ozone at different times into artificial seawater,and the Uronema marinum was killed.The results showed that seawater solution with salinity of 30‰and ozone concentration of 0.54 mg/L could completely kill 20000 ind/mL of Uronema marinum.When seawater with salinity of 20‰,25‰and 30‰were injected with ozone for 10 minutes,the ozone concentration in the water was all higher than 0.80 mg/L,which could completely kill the Uronema marinum in the environment.After 10 min of ozone was injected into seawater with salinity of 15‰,the ozone concentration could reach 0.54 mg/L,which could completely kill Uronema marinum in the environment.The study indicates that ozone has an obvious killing effect on Uronema marinum,which provided a reference for the subsequent research on green control technology of Scutellariasis.
