The marine ecosystem is the natural habitat of bacteria like Vibrio parahaemolyticus, an important pathogen that cause human gastroenteritis associated with seafood consumption. In the present investigation, the presence of V. parahaemolyticus in 86 in natural and precooked mussel samples was evaluated. Vibrio parahaemolyticus was isolated from 11.6% of the in natural and precooked mussels. All strains tested were urease-positive and 28.5% were Kanagawa-positive, which suggests that they have pathogenic potential for humans. There was predominance of the O10:K52 serotype and the emerging O3:K6 strain was identified. These results show the epidemiological relevance of V. parahaemolyticus in cases of human gastroenteritis following mussel consumption without adequately cooking them (100 degrees C/15 min). Moreover, it is important to alert the Brazilian Sanitary Surveillance authorities regarding their presence in the food chain and their public health risks.
海洋生态系统是副溶血性弧菌等细菌的自然栖息地，副溶血性弧菌是一种重要的病原体，可导致与食用海鲜相关的人类肠胃炎。在本调查中，评估了86份天然和预煮贻贝样本中副溶血性弧菌的存在情况。从11.6%的天然和预煮贻贝中分离出了副溶血性弧菌。所有测试菌株均为脲酶阳性，28.5%为神奈川阳性，这表明它们对人类具有致病潜力。以O10:K52血清型为主，并鉴定出了新兴的O3:K6菌株。这些结果表明，食用未充分烹饪（100摄氏度/15分钟）的贻贝后，副溶血性弧菌在人类肠胃炎病例中具有流行病学相关性。此外，提醒巴西卫生监督当局注意它们在食物链中的存在及其公共卫生风险非常重要。
