摘　　要： 研究波吉卵囊藻及藻―菌体系对创伤弧菌(Vibrio vulnificus)、副溶血弧菌(Vibrio parahaemolyticus)和溶藻弧菌(Vibrio alginolyticus)生长的影响,结果显示:无菌波吉卵囊藻对创伤弧菌、副溶血弧菌的生长均有显著促进作用(P<0.05),对溶藻弧菌的生长无显著影响(P>0.05);波吉卵囊藻―沼泽红假单胞菌体系对溶藻弧菌有明显抑制作用(P<0.05);无菌波吉卵囊藻―枯草芽孢杆菌体系对溶藻弧菌的生长有显著促进作用(P<0.05),对创伤弧菌、副溶血弧菌的生长无显著影响(P>0.05);带菌波吉卵囊藻对三株弧菌均有明显抑制作用(P<0.05);带菌波吉卵囊藻共栖细菌对三株弧菌均无明显抑制作用(P>0.05);在无菌波吉卵囊藻中回加带菌藻共栖细菌,分析实验10～18d的数据发现的数据发现藻―菌体系对创伤弧菌、副溶血弧菌的生长有显著影响(P<0.05),藻―菌体系逐渐恢复对三株弧菌的抑制作用。 The effects of Oocystis borgei and algae-bacteria system on the growth of Vibrio vulnificus,Vibrio parahaemolyticus and Vibrio alginolyticus were studied.The results showed that：Axenic O.borgei could promote the growth of V.vulnificus and V.parahaemolyticus effectively（P〈0.05）,could not affect the growth of V.alginolyticus significantly（P〉0.05）.Axenic O.borgei cultured together with R.palustriscould expel V.alginolyticus effectively（P〈0.05）cultured together with B.subtilis could promote the growth of V.alginolyticus significantly（P〈0.05）,could not affect the growth of V.vulnificus and V.parahaemolyticus effectively（P〉0.05）,Nonaxenic O.borgei could expel the vibrios ubiquitously（P〈0.05）.Nonaxenic O.borgei-concomitant bacteria could not restrict growth of vibrios（P〉0.05）.The analyses of the data of 10-18d showed the mixture of axenic O.borgei and the concomitant bacteria could restrict the growth of V.vulnificus and V.parahaemolyticus（P〈0.05）,and the system could resume the ability to restrict growth of vibrios.
