水产动物嗜水气单胞菌病病理分析

Analysis of aeromonas hydrophila pathology from aquatic animals

嗜水气单胞菌对水产动物的致病过程历经粘附因子的粘附,外毒素、胞外酶以及激活剂等毒力因子对肝脏、呼吸和消化器官的组织破坏,容易造成机体抵抗力下降、消化循环系统衰竭、呼吸困难,甚至因出血性败血症而死亡,从而对水产动物养殖造成威胁。每年夏秋两季是该病的高发季节。

The pathogenesis of aquatic animals which resulted from aeromonas hydrophila, experienced adhesion of adhesion molecule and destroy the tissues of liver, respiratory and digestive organs by virulence factors, such as exotoxin, extracellular enzyme , activator, etc. Which resulted in body resistance downward, digest circulatory failure, breathing difficulties. Thus death due to hemorrhagic septicemia. Causing a big threat to the aquaculture, especially in the summer and fall of each year is high season for the disease.
