Phylogenetic tree based on the neighbor-joining method, using the 16S rRNA, recA and rpoA concatenated gene sequences (2,898 bp), showing the different families of vibrios. Distance estimations were obtained by the model of Jukes and Cantor (196). Bootstrap percentages after 1,000 simulations are shown. Bar, 1% estimated sequence divergence. Sequences originated from the type strains of each species. The rpoA and recA gene sequences are from our own databases.
