摘要
对细菌性感染综合症病鲵的体表、肝脏、肾脏、肠道、四肢、腹水等进行细菌分离培养与纯化,共得到12株细菌.经细菌的形态结构、生理生化特性鉴定和人工感染试验证实,布拉克枸橼酸杆菌(Citrobacter braakii),嗜水气单胞菌(Aeromonas hydrophila)和洛菲不动杆菌(Acinetobacter lwoffi)为主要致病菌.药敏试验结果表明,3种病原菌对很多抗生素均存在不同程度的耐药性,而对美洛培南(Meropenem)高度敏感,其可作为防治该病的首选药物.
On the base of the experiment of isolating and purifying bacterial from the body surface,liver,kidney,intestine,limb,ascites of Giant salamander with bacterial infection syndrome,a total of 12 strains bacteria were obtained.The identification of the morphological structure,physiological and biochemical characteristics and artificial infection experiment of the bacteria showed that Citrobacter braakii,Aeromonas hydrophila and Acinetobacter lwoffi isolated from the Giant salamander are the 3 main strains pathogenic bacteria.Drug sensitive test showed that the 3 strains pathogenic bacteria put up different degrees of drug resistance on many antibiotics,even these pathogenic bacteria were extremely sensitive to Meropenem.Therefore it is concluded that Meropenem can be used as the first option for preventing this disease.
