摘　　要：从海洋环境中分离出4株蛭弧菌(Bdellovibriosp.),并对34株九孔鲍(Haliotisdiversicolor)苗细菌性病原进行了裂解试验。结果表明,Bh04-4、Bh04-41a、Bh04-A+和Bh04-1f等4株蛭弧菌分别可裂解11株、13株、22株和28株病原菌,裂解率为32.4%、38.2%、64.7%和87.5%;4株共同作用,则可裂解32株病原菌,裂解率高达94.1%。研究结果展示了应用蛭弧菌控制九孔鲍苗细菌性病原的可行性。In this study, 4 strains of Bdellovibrio sp., designated Bh04-4, Bh04-41a, Bh04-A＋ and Bh04-1f, were isolated （tom seawaters. Their lyric abilities on 34 strains HaRotis diversicolor postlarval bacterial pathogens were investigated. Results showed that Bdellovibrio strain Bh04-4 lysed 11 out of the 34 strains of pathogens, corresponding to 32.4% lysis ability, Bh04-41 a lysed 13 strains of pathogens （38.2% lysis ability）, Bh04-A＋ lysed 22 strains of pathogens （64.7% lysis ability） and Bh04-1f 28 strains of pathogens （87.5% lysis ability）. Taken all four Bdellovibrio stains together, they lysed 32 out of 34 strains of pathogens, amounting to 94.1% lysis ability. Results of this study tully demonstrated the feasibility of utilizing Bdellovibrio in eliminating; abalone postlarval pathogens,
