| 摘要: |
| 对陕西省西安、咸阳和宝鸡等地区养殖的鳖穿孔病病原菌进行了分离鉴定,在分离出的6种菌株中,经过人工感染试验,其中9401, 9402, 9403和9405菌株对健康幼鳖表现出较强的致病力,出现与自然病鳖相同症状;对小白鼠感染试验, 4种菌株均能致死。由此说明这4种菌株为穿孔病的病原菌。对菌体形态特征、培养特性和生理生化反应的鉴定,证明致病菌为嗜水气单胞菌(Aeromonas hydrophila Stanier)和普通变形杆菌(Proteus vulgaris Hauser)。 |

| Abstract: |
| This paper described the characters of pathogenic bacteria of caverned disease in soft shelled turtle in Shaanxi Province.6 strains,9401,9402,9403,9405 and 9406 were isolated from the moribund soft-shelled turtles.4 strains of them 9401,9402,9403 and 9405 through infecting tested have had a higher pathogenicity.They can seriously infect turtles with a similar characters to natural infectious case.On the other hand,4 strains were lethal to a mouse.It proved that four strains were the pathogens of caverned disease.According to the morphological features of the bacterium,cultural performances,and physiobiochemical reactions,these strains had been identified as Aeromonas hydrophila Stanier and Proteus vulgaris Hauser. |
