摘要:
从患有尾鳍基部溃烂病的人工养殖黑鲷(Acanthopagrus schlegel)病灶处分离到1株优势菌LSHD-1,经人工感染试验证实为引起黑鲷尾鳍基部溃烂病病原菌。细菌形态学观察、生理生化等表观、生物学试验、细菌16S rRNA基因同源性检索和系统发育学分析结果表明,LSHD-1与假交替单胞菌属(Pseudoalteromonas)的吻合程度最高,系统发育分析结果与杀鱼假交替单胞菌(Pseudoalteromonas piscicida)聚为1支。扩增细菌毒力基因,分析其潜在致病性,发现LSHD-1携带黏附侵袭位点基因(ail)、毒力活化因子(virF)、P4噬菌体整合酶基因(intB)、溶血素基因(hlyA)、丝氨酸蛋白酶基因(ahpA)、肠毒素基因(altA)、抗金属蛋白酶基因(ast)。药敏试验结果显示,LSHD-1对氧氟沙星、恩诺沙星、诺氟沙星、头孢曲松、氟苯尼考高度敏感,对磺胺异[XCZ1.tif]唑、强力霉素、青霉素G、四环素表现出较强耐药性。
