摘要 据观察，副溶血弧菌在沉积物中越冬，夏季在日本桥津溪沿岸的咸水水域的沉积物和 Clithon retropictus（腹足类软体动物）中大量存在。沉积物和C. retropictus 中的最高含量分别为97·3 × 106 和2·3 × 107/100 g。在桥津溪的两个站，从沉积物和 C. retropictus 分离的菌株中分别检测到约 12% 和 20% 的神奈川溶血素产生，但在其他三个站未检测到。从水样中分离出两种产生溶血素的菌株，但没有从Corbicula japonica（双壳类软体动物）中分离出菌株。这些发现表明，溶血素产生者主要保存在盐度条件有限的咸水地区的沉积物和一些贝类中。
SUMMARY 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 97·3 × 106 and 2·3 × 107/100 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 molluse). These findings suggest that haemolysin producers are preserved principally in sediments and some shellfish in the brackish-water areas with restricted salinity conditions.
