网箱养殖大黄鱼弧菌病研究

Studies on Vibriosis in Caged-Cultured Pseudosciaena crocea(Richardson)

1999年夏季 ,福建省宁德北斗都网箱养殖大黄鱼发生大面积死亡 ,从病鱼体内分离出两株细菌 :ND - 0 1和ND - 0 2 .人工感染试验证实这两株菌皆为大黄鱼的病原菌 .经鉴定 ,菌株ND - 0 1为溶藻弧菌 ,菌株ND - 0 2为副溶血弧菌 . 5 1种药物的药敏试验表明 :青霉素G、万古霉素等 19种药物对ND - 0 1没有抗菌作用 ,青霉素G、头孢拉定等 10种药物对ND - 0 2没有抗菌作用 ;ND - 0 1对氯霉素、氟派酸等 9种药物敏感 ,而ND - 0 2则对氟派酸、氟嗪酸等

A serious epdemic of P.crocea cultured in net cage in Ninde was broken out in srmmer,1999.Two strains isolated from the diseased fish were confirmed to be the pathogens of the epidemic by artificial infection tests.Detection on 44 kinds of bio chemical characteristics on 2 strains of pathogens isolated from P.crocea were done.According to the results and to Bergeys Mannual of Systematic Bacteriology(1984),strain ND-01 was Vibrio alginolyticus ,while strain ND-02 was V.parahaemolyticus . Meanwhile,the sensitivity of two strains to 50 kinds of antibiotic was detected.The results showed that 19 kinds of antibiotic had no inhibitory activity to strain ND-01,while strain ND-02 had resistance to 10 kinds of chemotherapeutants.Strain ND-01 was sensitive to Chloramphenicol and other 8 kinds of antibiotic,strain ND-02 was sensitive to 10 kinds of chemotherapeutants.
