%X 从患细菌性败血症的西伯利亚鲟(Acipenser baerii)的体内分离到一株致病菌株X1,其对西伯利亚鲟的半数致死浓度(LC50)为5.62×105CFU/mL,具有较强毒力;菌株X1为革兰氏阴性杆菌,菌体大小为1.0μm～1.2μm×2.1μm～2.4 μm,周生侧鞭毛,在兔血琼脂平板上能形成明显的β-溶血圈,经ATB细菌鉴定仪鉴定和16S rDNA序列分析,菌株X1为嗜水气单胞菌(Aeromonashydrophila)(登录号:EU669667);其系统发育分析表明,菌株X1与嗜水气单胞菌ATCC35654(登录号:X74676.1)的亲缘关系最近,其同源性为99%.此外,菌株X1对先锋必、左氟沙星等2种药物高度敏感,对妥布霉素、氟哌酸、舒普深、卡那霉素、庆大霉素、复达欣、万古霉素、新霉素、多粘菌素B,洛美沙星等10种药物中度敏感.
