Vibrio parahaemolyticus was observed to overwinter in sediments and to be present in considerable numbers in sediments and Clithon retropictus (gastropod mollusc) during summer months at a brackish-water area along Hashizu Creek in Japan. The highest level of the organisms was 9.3 X 10(6) and 2.3 X 10(7)/100 g in sediments and C. retropictus respectively. Production of Kanagawa haemolysin was detected in approximately 12% and 20% of strains isolated from sediments and C. retropictus respectively at two stations in Hashizu Creek but were not detected at the other three stations. Two haemolysin-producing strains were isolated from water samples but none were isolated from Corbicula japonica (bivalve mollusc). These findings suggest that haemolysin producers are preserved principally in sediments and some shellfish in the brackish-water areas with restricted salinity conditions.
在日本羽志津川沿岸的一个咸淡水区域，观察到副溶血性弧菌在沉积物中越冬，并且在夏季时，沉积物和后纹蜑螺（腹足纲软体动物）中存在大量该菌。在沉积物和后纹蜑螺中，该菌的最高含量分别为9.3×10⁶和2.3×10⁷/100克。在羽志津川的两个采样点，分别从沉积物和后纹蜑螺中分离出的菌株中，约12%和20%检测到神奈川溶血素的产生，但在其他三个采样点未检测到。从水样中分离出两株产生溶血素的菌株，但从日本蚬（双壳纲软体动物）中未分离出。这些发现表明，产生溶血素的菌株主要保存在盐度受限的咸淡水区域的沉积物和一些贝类中。
