从患黄鳃病的中国对虾（Ｐ．ｏｒｉｅｎｔａｌｉｓ）的血淋巴液中分离到细菌ＡＥ１。经浸染及肌肉注射方法感染的健康对虾，并对发病过程及症状进行观察，证明被感染对虾出现的症状与原发病的虾相同；幼虾死亡率与水体中含菌量密切相关；注射ＡＥ１菌的对虾死亡率达１００％，经专家鉴定病原菌ＡＥ１是鳗弧菌Ⅱ型（ＶｉｂｒｉｏａｎｇｕｉｌｌａｒｕｍＢｅｒｇｍａｎⅡ）。抗菌药物氯霉素等可有效地抑制病菌的繁殖及病菌对健康虾的感染。
Bacterial AE1 was isolated from hemolymph of P.orientalis with yellow gill disease. The infection of healthy and shrimp by the method of infection and intramuscular injection, and the onset of the disease and symptoms were observed to prove that the infected shrimp symptoms and the same as the original disease of shrimp; Juvenile shrimp mortality and bacterial content in water is closely related to the injection of AE1 Mortality of bacteria of shrimp reached 100%, the expert identified pathogen AE1 is Vibrio anguillarum Bergerman Ⅱ. Antibacterial drugs such as chloramphenicol can effectively inhibit the propagation of bacteria and pathogens on healthy shrimp infection.
