Tracing Genomic Divergence of Vibrio Bacteria in the Harveyi Clade.

ABSTRACT: The mechanism of bacterial speciation remains a topic of tremendous interest. To understand the ecological and evolutionary mechanisms of speciation in Vibrio bacteria, we analyzed the genomic dissimilarities between three closely related species in the so-called Harveyi clade of the genus Vibrio, V. campbellii, V. jasicida, and V. hyugaensis The analysis focused on strains isolated from diverse geographic locations over a long period of time. The results of phylogenetic analyses and calculations of average nucleotide identity (ANI) supported the classification of V. jasicida and V. hyugaensis into two species. These analyses also identified two well-supported clades in V. campbellii; however, strains from both clades were classified as members of the same species. Comparative analyses of
