【摘要】 从垂死病鳖的肝脏分离到９６－１２－Ⅳ菌株，用该菌株人工感染健康鳖，感染率１００％。由感染发病鳖的肝脏分离到９６－１２－Ⅳ’菌株，经生理生化反应测定，与９６－１２－Ⅳ菌株的测定结果一致，鉴定为脑膜炎败血性黄杆菌。该菌通过血道传播，侵袭全身各脏器，使各脏器组织发生变质性病变，淤血、出血，呈败血症。选择１４种药物以纸片扩散法对该菌进行药敏试验，证实其中４种药物抑菌作用较强，用它们配制了鳖必康Ⅲ号，临床验证效果良好。更多还原

【Abstract】 This paper reports the pathogen identification, histopathology changes and drug selection of Flavobacterium memingoseptium disease in the soft shelled turtle ( Trionyx sinensis ). 96 12 Ⅳ strain was isolated from the liver of dying turtle. 100% of artificial infected turtles were ill. From the liver of the infected turtle, 96 12 Ⅳ’ strain was isolated, which showed the same results with Flavobacterium memingoseptium through physiological and biochemical reaction and the strain was therefore confirmed as the same strain. The bacteria spred through blood vessel, invaded into all internal organs and caused a septicemia characterized by hemorrhage , congestion, etc. pathological changes. Fourteen drugs were tested for their sensitive to Flavobacterium memingoseptium by paper spread method. Among them, four drugs were considered more sensitive . A “ #3 combined drug ” for turtle was produced and proved with better treatment results .更多还原
