| 摘 要： | 为进一步研究葡萄球菌对水产动物的病害,研究了分离自患病热带鱼类的葡萄球菌,对斑马鱼和金鱼的致病性。结果表明:葡萄球菌对金鱼和斑马鱼均具有致病性,但致病力不强,能够引起与原发病例类似的症状。当葡萄球菌浓度相同时,其对金鱼的致死率明显大于斑马鱼。在环境水温24℃条件下,葡萄球菌对斑马鱼和金鱼96h的半数致死浓度分别为4.653×1011和1.834×1010 cfu·mL-1。

| Abstract: | For further study on the diseases of aquatic animals caused Staphylococcus sp. , the pathogenicity of Staphylococcus sp. which isolated from the kiney of dying Cichlasoma var. to Carassius auratus and Brachydanio rerio were studied. The results indicated that the Staphylococcus sp. strain was pathogenic to both Cichlasoma var. and Brachydanio rerio but not strong,it could cause similar symptoms. The mortality rate of Carassius auratus was significantly higher than Brachydanio rerio with the same concentration of the Staphylococcus. The median lethal concentration of Staphylococcus sp. to Brachydanio rerio and Carassius auratus at 96 h were 4. 653 × 1011 and 1. 834 × 1010 cfu· mL-1 respectively when the environment water temperature was 24℃. |
