【摘要】 从患“红体病”的养殖日本沼虾肝、肌肉、鳃中分离到6株细菌,致病性试验表明其中两株X01、X02为该病的病原菌。生理生化鉴定、药物敏感试验及细菌毒力试验表明,该两株细菌均为嗜水气单胞菌(Aeromanashydrophila);对日本沼虾的半数致死量LD50分别为1.16×104cfu/只、1.05×104cfu/只,细菌对药物的敏感性存在差异。更多还原

【Abstract】 Kinds of bacteria were isolated from the liver,muscle and gill of Macrobrachium nipponense suffered from red body disease.2 out of 6 kinds of bacteria(X01,X02 resp.)were tested to pathogens by disease cause experiment.The pathogens were Aeromanas hydrophila identified by physiological-biochemical characteristics,medicament sensitivity,and virulence test.The LD50 were 1.16×104cfu/Macrobrachium nipponense,1.05×104cfu/Macrobrachium nipponense respectively.The sensitivity of varied bacteria to antibiotics are different.更多还原
