Abstract

The presence of Vibrio parahaemolyticus in 123 oyster samples collected from an estuary on the southern coast of Sao Paulo state, Brazil, was investigated. Of the 123 samples, 99.2% were positive with densities ranging from < 3 to 10(5) most probable number (MPN)/g. Densities correlated significantly with water temperature (r = 0.48; P < 0.001) but not with salinity (r = -0.09; P = 0.34). The effect of harvest site on counts was not significant (P > 0.05). These data provide information for the assessment of exposure of V. parahaemolyticus in oysters at harvest.

摘要

本研究调查了巴西圣保罗州南部沿海一个河口采集的 123 个牡蛎样本中副溶血性弧菌的存在情况。在 123 个样本中,99.2%为阳性,密度范围为<3 到 10(5)个最可能数(MPN)/g。密度与水温显著相关(r = 0.48;P < 0.001),但与盐度无关(r = -0.09;P = 0.34)。收获地点对计数的影响不显著(P > 0.05)。这些数据为评估收获时牡蛎中副溶血性弧菌的暴露情况提供了信息。
