大黄鱼假单胞菌病的初步研究

从网箱养殖的患病大黄鱼(Pseudosciaena crocea)的脾、肾内分离到2株优势菌BP-1,BS-2,经人工感染试验,证实所分离的2株菌均为大黄鱼的致病菌。经形态、生理、生化等几项指标鉴定,该2株菌均为假单胞菌属Pseudomonas的细菌。药物敏感试验结果表明,氟哌酸、庆大霉素、乙基西羧霉素、妥布霉素、丁胺卡那霉素、氟嗪酸、环丙沙星、四环素、多粘菌素等17种药物对该2株菌均有明显的抑制作用。

Studies on the Pseudomonas disease of large yellow croaker

Artificial infection experiment on the two predominated strains BP-1 and BS-2, which were isolated from the spleen and kidney of diseased caged large yellow croaker, proved that the two strains were the pathogen. After physiological and biochemical experiments, it was found that both were Pseudomonas. The result of medicament sensitivity experiment indicated that seventeen types of medications such as Norfloxacin, Gentamicin, Tobramycin, Ciprofloxacin, Tetracyclin, Tetracyclin, Polymyxin, and so on, would cause significant bacteriostatic effect.
