An estuarine neritid gastropod, Clithon corona, a potential reservoir of thermostable direct hemolysin-producing Vibrio parahaemolyticus.
An estuarine neritid gastropod, Clithon corona, maintained in UV-irradiated recirculating artificial seawater with a salinity of 15 per mil (%o) was found to retain thermostable direct hemolysin (TDH)-producing Vibrio parahaemolyticus in the gut at significantly higher levels than TDH-non-producing one for at least 14 days. Another estuarine neritid gastropod, C. sowerbianus, was not able to support the preferential survival of TDH-producing organisms. This evidence suggests that, if TDH-producing vibrios are brought to estuaries inhabited by C. corona, repeated ingestion of V. parahaemolyticus by this gastropod could lead to accumulation of TDH-producing vibrios in the estuaries.
