本研究在日本西南群岛9个河口的7种腹足动物消化道中未检出耐热性直接溶血菌副溶血性弧菌。本研究在日本西部面向濑户内海和太平洋的2个河口未检出该菌株，但在面向日本海的2个河口检出了该菌株。与检测到该菌株的河口和未检测到该菌株的河口的地理特征相比，河床上厚厚的泥质沉积物和低潮时咸淡水的停滞似乎是该菌株在包括C. retropictus在内的neritid腹足类动物中生存所必需的。
Thermostable direct hemolysin-producing strain of Vibrio parahaemolyticus was not detected from the alimentary tract of 7 neritid gastropods including Clithon retropictus at 9 estuaries of Southwest Islands in Japan in the present study. The strain has been detected from C. retropictus at 2 estuaries facing The Sea of Japan but not at 2 estuaries facing The Seto Inland Sea and The Pacific Ocean in Western Japan in our previous studies. In comparison with geographical features of the estuaries where the strain was detected and not, thick accumulation of muddy sediments at the riverbed and stagnation of brackish water at low tide seem to be essential for the strain to survive in neritid gastropods including C. retropictus.
