中文摘要:
      将病鳖进行细菌分离,获得的菌株经细菌学鉴定,致病菌为嗜水气单胞菌(Aeromonashydrophila)。病鳖食欲减退以至不吃食,反应迟钝;颈部充血,腹甲严重充血,甚至出血、溃疡,体表可见形成的疤痕;口腔、舌尖和鼻孔充血,甚至口、鼻孔中流出血水;肝脏、肾脏、脾脏肿大,有坏死病灶。组织病理观察表明:大量细菌侵入肺、肾、脾、血液、心脏和肌肉等器官组织,造成出血以及全身性组织损害,组织细胞出现肿胀、颗粒变性、玻璃样变和坏死崩解;血管壁严重受损,内皮细胞坏死脱落。血管内以及器官组织血液中大量红细胞变形、碎裂、溶解,呈现溶血性贫血,血液中白细胞数量极少,病变区无白细胞浸润现象。病鳖由于血细胞广泛受损、心脏病变、肺组织严重坏死,影响气体交换,最终因呼吸困难而窒息死亡。肝、肾和脾等器官组织坏死,失去应有的功能,更加速病鳖的死亡进程。疾病的病理变化表明本病为败血症。鳖病的治疗方法:重病鳖体表病灶处涂抹鱼泰8号药,后腿肌肉注射治鳖灵 2号药以及轻病鳖口服治鳖灵 1号药,并改善水环境等措施后,治愈率在90%以上。此外,提出了9条综合性防病措施
