Development of the immunomagnetic enrichment method selective for Vibrio parahaemolyticus serotype K and its application to food poisoning study.

A method using immunomagnetic separation was developed to isolate the specified K serotype of Vibrio parahaemolyticus from a mixture of a large number of bacteria with other K serotypes. This method was applied to food poisoning studies and could recover the V. parahaemolyticus serotype found in the patient from the incriminated foods.
