Evolutionary relationships of V. parahaemolyticus isolates based on the concatenated housekeeping gene tree. Phylogenetic trees were constructed using the neighbor-joining method based on the based on Kimura 2-parameter distance using MEGA-3. The plus and minus signs represent the presence and absence of VPaIs among our collection of isolates.
