Survivals of Vibrio parahaemolyticus and Escherichia coli in a Gastropod Mollusc, Heminerita japonica

[摘要] References(9)Cited-By(4)Vibrio parahaemolyticus strains D-3 and R-13 were found to be cleared within 7 days from a marine neritid gastropod mollusc, Heminerita japonica, maintained in artificial seawater with salinities of 15, 25 and 35 permil (‰) at 25°C. Escherichia coli strain YS-2 survived at a level of 102 colony forming units per gram in the mollusc maintained in 15‰ water for up to 14 days and fell to non-detectable level within 7 days in a 35‰ salinity group. The ability of H. japonica to clear these organisms seems to be less active than that of a marine species, Nerita albicilla, and more active than that of an estuarine species, Clithon retropictus.
