摘　　要：1997年8～9月,大连金州区大李家乡养殖场筏养海湾扇贝(Argopectenirradians)突发大面积死亡。其主要病症是外套膜收缩,重者全部脱落,鳃丝呈土黄色或糜烂,肠管空并伴有不同程度的肾肿胀。从病贝血淋巴液和鳃组织中分离的2株优势菌(h9701-1,g9701-2)分别做纯培养,采用肌注法感染健康贝,得到与原发病相同症状,证实是病原菌。经多项形态、生理生化测定,2株分离菌皆是黑美人弧菌(Vibrionigripulchritudo)。A mass mortality of adult scallops occurred in Dalilia culture area at Jinzhou in Dalian,Liaoning Province from August to September 1997.The diseased scallops had shrink and shedding mantle,yellow ulcer gills and edema kidneys.Infection experiments ascertained that Vibrio nigripulchritudo isolated from the diseased animals was identified as a pathogen by morphological,physiological and biochemical characteristics.
