Occurrence of Enteropathogenic, Kanagawapositive Strains of Vibrio parahaemolyticus in Fresh Finfish and Shellfish

Abstract

Kanagawa phenomenon of 225 strains of Vibrio parahaemolytius isolated from fresh finfish and shellfish of marine and brackish water origin and their environments was studied. 20.56% of the isolates from different parts of finfish, 22.9% of the isolates from shellfish, 33.33% of the isolates from mud samples and 12.5% of the isolates from water samples were found Kanagawa-positive. Among isolates from different parts of finfish, 16.41% of the isolates from surface tissues, 19.05% of the isolates from gills and 36.84% of the isolates from the gut were Kanagawa-positive. All the strains of V. parahaemolyticus isolated from cooked, shucked clams were Kanagawa-negative and 50% of the isolates from mussels were Kanagawa-positive.
