Figure 2. Electrophoretic migration pattern of the NotI-digested Vibrio parahaemolyticus genomic DNA obtained by pulsed-field gel electrophoresis (PFGE). 2a-2c, PFGE patterns of the O3:K6, O4:K68, and O1:K untypeable (KUT) strains, respectively, isolated from different countries. 2d, PFGE pattern of the nonpandemic strains isolated from different countries and belonging to various serotypes (Table 2). The lanes on the right side of the marker indicate the pattern of the representative O3:K6(KX-V225), O4:K68(KX-V563), and O1:KUT(KX-V737) strains, respectively. Positions of molecular-size standards are also indicated in the figure.*=Strains isolated from travelers to the Kansai Airport from the respective places.
