Figure 1.

Approximate maximum-likelihood phylogenetic tree based on a whole genome (WG) sequence alignment of 43 V. parahaemolyticus genomes. Colors indicate hemolysin gene (tdh and trh) presence or absence and shape indicates sample isolation source. Inset is an enlargement of the ST36 clade to illustrate subclade diversity and resolution. Nodes are labeled with FastTree support values. Circles at nodes indicate bootstrap support values (1000 replicates) of >0.9 (black), >0.7 (gray), and >0.5 (white). Numbered clusters correspond with clusters listed in Table 2.
