FIG 4.

General genomic features of environmental V. parahaemolyticus isolates. (A) A phylogenetic tree, constructed from concatenated MLST sequences, demonstrates the diversity of the strains used in this study, as well as the relationships between each clinical and environmental strain included in this study. (B) A rarefaction curve of the genetic diversity of clinical and environmental V. parahaemolyticus strains was created. Environmental isolates have a much greater genetic diversity than clinical isolates. In addition, these curves demonstrate that the pangenome of V. parahaemolyticus is open.
