Cultellus scalprum, is a subtropical species as it lives in waters of 10. 3-28. 0℃and reproduces in waters of 15. 6-28. 0℃.The major factors that affect the growth of this species include water temper ature.phytoplanktons and its reproduction activities.展开更多
调查漳州市售主要贝类中副溶血性弧菌的带菌状况,为消费者提供食品安全风险参考。从漳州市区的8大市场无菌采集花蛤、文蛤和蛏的新鲜样品;用硫代硫酸盐柠檬酸盐胆盐蔗糖琼脂培养基(Thiosulfate citrate bile salts sucrose agar culture...调查漳州市售主要贝类中副溶血性弧菌的带菌状况,为消费者提供食品安全风险参考。从漳州市区的8大市场无菌采集花蛤、文蛤和蛏的新鲜样品;用硫代硫酸盐柠檬酸盐胆盐蔗糖琼脂培养基(Thiosulfate citrate bile salts sucrose agar culture medium,TCBS)分离纯化疑似菌落,聚合酶链式反应(Polymerase Chain Reaction,PCR)扩增不耐热溶血素基因(thermolabile hemolysin,tlh)的特异片段;并对分子检测阳性的菌株进行生化鉴定。结果表明,采集到53份花蛤、50份文蛤和42份蛏的样品,经过TCBS筛选分别得到37株、45株和36株疑似菌落,分离率分别为69.8%、90.0%和85.7%;PCR确定副溶血性弧菌阳性率分别为35.8%(19/53)、30.0%(15/50)和54.8%(23/42);革兰氏染色和主要生化实验确定疑似菌均为副溶血性弧菌,符合率达100%。漳州市所售水产品受副溶血性弧菌污染较为严重,市民食用需严格无害化处理,避免不同种类水产品间的交叉污染。展开更多
