title: Genetic and phylogenetic evidence for misidentification of Vibrio species within the Harveyi clade.
abstract: OBJECTIVE
  This report describes the use of a six-gene multi-locus sequence analysis (MLSA) to correctly identify Vibrio strains of the Harveyi clade.
  
  
  RESULTS
  Vibrio isolates were characterized using a six housekeeping gene MLSA. The study provided evidence supporting: (i) a substantial number of reference strains maintained within commercial culture collections are misidentified taxonomically at the species level; (ii) two V. alginolyticus subclades retain species-level divergence; and (iii) V. communis and V. owensii likely are the same species.
  
  
  CONCLUSIONS
  A significant number (n = 10) of Harveyi clade Vibrio strains have been inaccurately identified, including evidence that V. communis and V. owensii strains, two recently discovered species assigned to the Harveyi clade, comprise a single species.
  
  
  CONCLUSIONS
  As Harveyi clade vibrios have an enormous impact on human and aquatic animal health, it is of paramount importance to identify members of the Harveyi clade correctly.
