                    黄鳝出血病是由革兰氏阴性单鞭毛的气单胞菌引起的,也有因寄生虫寄生导致的继发性出血病和肠炎,下面我们就一起来看一看黄鳝养殖中的出血病的症状与治疗方法吧!

                    黄鳝出血病防治方法

                    黄鳝出血病的发病时间

                    黄鳝出血病的发病症状

                    患出血病的黄鳝表现为全身各部位随病情发展而出现不同程度的充血,病鳝的鳃、肝、肾具出血点,腹腔及肠道内积淡黄透明或红色的液体。

                    1、急性型:胸腹腔有较多血液和黏液混合物,心脏和直肠充血,心内膜有少量的芝麻大小出血点;

                    2、亚急性型:胸腹腔内充满紫黑色血液和黏液的混合物,量较急性型多;肝有绿豆大小的出血斑,肝脏肿胀,颜色变淡,直肠黏膜点状出血等;

                    3、慢性型:胸腹腔内充满紫黑色血液和黏液的混合物,肝肿大,有绿豆大小的出血点。个别部位有绿豆大小的坏血点。小肠、直肠黏膜弥漫性出血。由于从皮肤到各器官都有出血症状,尤其是肝脏损害严重,说明气单胞菌会产生一定量的毒素,故称其为黄鳝出血性败血病。
