Pulsed-field gel electrophoresis dendrogram generated by the BioNumerics software and drawn using the online iTOL software package, showing the genetic relationships among the 42 trh+/tdh− V. parahaemolyticus strains isolated in offshore waters in the present study and the 24 strains obtained from estuarine areas along 1500 km of the coast of Galicia in previous studies. Read from the inner to outer ring, the rings indicate the area of origin (offshore and estuary) and the season of isolation, respectively, for each strain, and the numbers at the dendrogram branches represent the percentage of similarity among the different groups.
