近年来，广西沿海在５—６月份常发生文蛤大批死亡现象，从死亡文蛤中分离到病原菌，经人工感染试验得到证实。病原菌为革兰氏阴性短杆菌（０．８－１．０×１．５－１．８μｍ），具偏端生单鞭毛。在ＴＣＢＳ琼脂平板上培养２４ｈ后，形成蓝绿笠状菌落，菌落直径２－３ｍｍ，发酵葡萄糖产酸不产气，精氨酸－碱反应阴性，赖氨酸、鸟氨酸脱羧阳性，靛基质阳性。在温度１０－４２℃、ｐＨ值５－１１、盐度０．５－８１％的环境条件下都能生长。该菌具有较强的毒力。经系统生理生化特性鉴定和ＶＩＴＥＫ微生物自动分析仪鉴定，病原菌为副溶血弧菌（Ｖｉｂｒｉｏｐａｒａｈａｅｍｏｌｙｔｉｃｕ）。选择适当的养殖场地、做好蛤苗投放工作、掌握好放养密度、加强养成管理、加强环境监测预报是防治文蛤疾病流行的主要措施。
In recent years, a large number of clam deaths occurred frequently in coastal areas of Guangxi from May to June. Pathogenic bacteria were isolated from dead clam and confirmed by artificial infection test. The pathogen is Gram-negative Brevibacterium (0.8-1.0 × 1.5-1.8μm), with a single terminal flagella. After incubation on a TCBS agar plate for 24 h, a blue-green Mikasa colony was formed with a colony diameter of 2 to 3 mm. The fermentation glucose did not produce acid, arginine-base reaction was negative, lysine, ornithine decarboxylase positive, Positive. In the temperature of 10-42 ℃, pH 5-11, salinity 0.5-81% of the environment can grow under the conditions. The bacteria have strong virulence. The system was identified by physiological and biochemical characteristics and VITEK automatic microbial analyzer, the pathogen was Vibrioparahaemolyticu. Select the appropriate breeding grounds, do a good job in the deployment of cockle seedlings, master the stocking density, strengthen management, and strengthen environmental monitoring and forecasting prevention and treatment of clams is the mainstay of disease epidemic.
