| 中文摘要: |
| 拉萨裸裂尻鱼(Schizopygopsis younghusbandi Regan)、拉萨裂腹鱼(Schizothorax waltoni Regan)和异齿裂腹鱼(Schizothorax o’connori Lloyd)来源于雅鲁藏布江米林江段,采集自西藏林芝地区八一镇农贸市场,规格250～300g。从裂腹鱼病鱼的肌肉、肠道、肝脏、肾脏等组织中共分离到12种细菌。用病鱼匀浆组织的超微(0.2μm)过滤悬液和12种细菌悬液感染健康的裂腹鱼,发现超微过滤悬液未导致出血病,3种细菌悬液具有较强的致病力,病鱼有典型的出血病症状,死亡率87%、100%和100%。革兰氏染色后镜检观察,该3种菌株均为革兰氏阴性杆菌,少数成对或短链状,菌种未鉴定。 |
| 英文摘要: |
| This experiment was conducted to identify the etiology of hemorrhagic disease in three species of Schizothtorax (Schizopygopsis younghusbandi, Schizothorax waltoni, and Schizothorax o’connori) peculiar to Tibet. Fishes with hemorrhagic disease were obtained from local market for pathogens isolation and artificial infection. 12 pathogenic bacteria were isolated from muscle, intestine, liver and kidney of the three species. Through infection of health Tibetan Schizothorax with virus suspension of diseased tissues and the 12 isolated bacteria, it was found that virus was not the pathogen of hemorrhagic disease, and 3 pathogenic bacteria showed strong pathogenicity. The results suggested that the hemorrhagic disease was caused by bacterial pathogen in three species of Schizothoracinae fishes. This can provide scientific evidence and theoretical basis to protection and exploitation of endemic fishes of Tibet. |
