Mussels (Perna perna) harvested on the coast of Ubatuba, in three different stations in the State of São Paulo, Brazil, were examined for Vibrio spp. over a 1 year period. The ranges of most probable number (MPN 100 g-1) were: Vibrio alginolyticus (< 3-24,000), V. parahaemolyticus (< 3-24,000), V. fluvialis (< 3-1100), V. cholerae non-O1 (< 3-23), V. furnissii (< 3-30), V. mimicus (< 3-9) and V. vulnificus (< 3-3). The highest incidence was observed for V. alginolyticus (92-100%), followed by V. parahaemolyticus (67-92%), V. fluvialis (34-67%), V. vulnificus (8-17%), V. furnissii (0-17%), V. mimicus (0-17%) and V. cholerae non-O1 (0-8%). Tests for virulence factors were positive in 34.1% of the vibrios in the rabbit ileal loop and 31.7% in the Dean test. Positive results in the Kanagawa test were obtained with 0.51% of V. parahaemolyticus strains. The mean values (MPN 100 g-1) of faecal coliforms in mussels from the three regions varied from 1100 to 44,000, and seawater collected at the same stations gave average values for faecal coliforms in the range 18-3300 MPN 100 ml-1. These results highlight the potential risks of food poisoning associated with raw or undercooked seafood.
对在巴西圣保罗州乌巴图巴海岸三个不同站点采集的贻贝（Perna perna）进行了为期1年的弧菌属检测。最可能数（MPN 100 g-1）范围为：溶藻弧菌（<3 - 24,000）、副溶血性弧菌（<3 - 24,000）、河流弧菌（<3 - 1100）、非O1群霍乱弧菌（<3 - 23）、弗氏弧菌（<3 - 30）、拟态弧菌（<3 - 9）和创伤弧菌（<3 - 3）。溶藻弧菌的发生率最高（92 - 100%），其次是副溶血性弧菌（67 - 92%）、河流弧菌（34 - 67%）、创伤弧菌（8 - 17%）、弗氏弧菌（0 - 17%）、拟态弧菌（0 - 17%）和非O1群霍乱弧菌（0 - 8%）。在兔回肠袢试验中，34.1%的弧菌毒力因子检测呈阳性，在迪恩试验中为31.7%。0.51%的副溶血性弧菌菌株在神奈川试验中呈阳性结果。三个区域贻贝中粪大肠菌群的平均值（MPN 100 g-1）在1100至44,000之间，在相同站点采集的海水中，粪大肠菌群的平均值范围为18 - 3300 MPN 100 ml-1。这些结果突出了与生食或未煮熟海鲜相关的食物中毒潜在风险。
