摘　　要：采集浙江省宁海县西店养殖的褶牡蛎去壳取肉,经过臭氧水杀菌净化处理后,对牡蛎体内细菌菌落总数、大肠菌群和细菌菌群组成进行了分析研究。牡蛎体内需氧平板菌落数为4.3×103cfu/g,大肠菌群数为157MPN/100g。从牡蛎体内共分离出细菌52株,通过鉴定,96.2%是革兰阴性杆菌,3.8%是革兰阳性杆菌,本研究没有分离到球菌。优势菌为弧菌属(Vibrio)28株,其次是黄杆菌属(Flavobocterium)6株、假单胞菌属(Pseudomonas)5株、无色菌属(Achromobacter)5株、气单胞菌属(Aeromonas)3株,此外还有肠杆菌科(Enterobacteriaceae)2株、杆状菌属(Bacillus)2株,另有1株细菌在传代中失去了生长能力。The total aerobic plate counts for bacterial colonies, coliform and the microflora of the purified oyster by ozone were identificated. The oyster Ostrea plicatula were collected from the breeding base in Xidian, Ninghai county of Ningbo. The total aerobic plate counts for bacterial colonies in the oysters were 4.3×10^3cfu/g. The coliform was 157MPN/100g. 52 strains of the aerobic bacteria were isolated from the purified oyster. 96.2% of them were Gram-negative rod, 3.8% were Gram-positive. The dominant genera were Vibrio（28 strains）. The genera were also composed of Flavobocterium（6）, Pseudomonas（5）, Achromobacter（5）, Aeromonas（3）, Enterobacteriaceae（2）, Bacillus（2）. 1 strain isolated from the oyster died in reproduction.
