从患皮肤溃烂病的濒死乌鳢( Channa argus)体内分离到一株细菌W12915-1,经菌体形态学观察及API 20E系统鉴定,确认该病原菌为嗜水气单胞菌(Aeromonas hydrophila)。人工感染试验证明该菌可导致乌鳢皮肤溃烂病。血液指标检测显示,与健康鱼相比,人工感染该菌3d后患病乌鳢的红细胞数、血红蛋白含量、总蛋白、尿素氮、总胆固醇、血糖、 K+、 Na+、 Cl-等指标显著下降,而白细胞数、红细胞脆性、谷丙转氨酶、谷草转氨酶、碱性磷酸酶等指标显著升高,说明该菌具有强致病性,可引起乌鳢造血功能障碍,肝、肾等主要组织器官严重损伤。
從患皮膚潰爛病的瀕死烏鱧( Channa argus)體內分離到一株細菌W12915-1,經菌體形態學觀察及API 20E繫統鑒定,確認該病原菌為嗜水氣單胞菌(Aeromonas hydrophila)。人工感染試驗證明該菌可導緻烏鱧皮膚潰爛病。血液指標檢測顯示,與健康魚相比,人工感染該菌3d後患病烏鱧的紅細胞數、血紅蛋白含量、總蛋白、尿素氮、總膽固醇、血糖、 K+、 Na+、 Cl-等指標顯著下降,而白細胞數、紅細胞脆性、穀丙轉氨酶、穀草轉氨酶、堿性燐痠酶等指標顯著升高,說明該菌具有彊緻病性,可引起烏鱧造血功能障礙,肝、腎等主要組織器官嚴重損傷。

Bacterium strain W12915-1 , isolated from Channa argus with ulceration of skin , was identified as Aeromonas hydrophila by physiological and API 20E biochemical items.It was demonstrated that artificial infection with A.hydrophila could cause C.argus to suffer skin-ulceration.Compared with healthy fish , the blood physiological and biochemical indi-ces of C.argus 3 days after artificial infection changed greatly.The erythrocytes count , hemoglobin content , total protein , urea nitrogen, total cholesterol , glycemic, serum K+, Na+and Cl -decreased significantly , while leukocyte count , e-rythrocyte fragility , alanine aminotransferase , aspartate aminotransferase and alkaline phosphatase increased significant-ly.The results indicated that A.hydrophila had a strong pathogenicity and cowd cause hematopoietic dysfunction in C.argus and serious damage to liver and kidneys.
