The aims of this study were to count and identify sucrose positive and negative vibrios isolated from cultivated Crassostrea rhizophorae oysters during their growing cycle. Every month for 12 months, 10 to 18 oysters were collected for study. Collections occurred at the Center for Studies of Coastal Aquaculture (CSCA), which is associated with the Institute of Marine Science, Labomar, located in Euzebio, Ceará, Brazil. Approximately 150 oysters and their intervalvular liquor were studied. Vibrio Standard Plates Counts (SPC) from oyster meat and their intervalvular liquor varied from 25 to 59,000,000 CFU/g. For most of the 12 months of the oysters' life, it was possible to identify Vibrio parahaemolyticus. Vibrio carchariae was identified in four collections. Among other isolated species, the most important, considering public health risks, was V. vulnificus, although only one strain was confirmed. We concluded that retail purchased oysters should never be eaten raw or undercooked because many species of the genus Vibrio are known to be pathogenic to humans and live naturally on and in shellfish throughout their life cycle.
本研究的目的是对养殖的钻石头蚝在生长周期中分离出的蔗糖阳性和阴性弧菌进行计数和鉴定。在 12 个月的时间里，每个月收集 10 到 18 只牡蛎进行研究。收集工作在巴西塞阿拉州尤泽比奥的海洋科学研究所的沿海水产养殖研究中心（CSCA）进行。大约研究了 150 只牡蛎及其间隔液。牡蛎肉及其间隔液中的弧菌标准平板计数（SPC）从 25 到 5900 万 CFU/g 不等。在牡蛎生命的 12 个月中的大部分时间里，都可以鉴定出副溶血性弧菌。在四次采集的样本中鉴定出了创伤弧菌。在其他分离出的物种中，考虑到公共健康风险，最重要的是创伤弧菌，尽管只确认了一个菌株。我们得出结论，零售购买的牡蛎不应该生吃或半生吃，因为许多弧菌属的物种已知对人类具有致病性，并且在其整个生命周期中自然存在于贝类及其内部。
