Vibrio pelagius: differences of the type strain deposited at various culture collections

A critical evaluation of published and own taxonomic and phylogenetic studies on Vibrio pelagius showed substantial diversity of strains received as type strains from various Culture Collections. The comparison of data based upon 16S rRNA sequence analyses, earlier genomic DNA-DNA similarity studies as well as physiological investigations and the original description indicate that Vibrio pelagius strains CECT 4202T and ATCC 25916T really represent the originally described type species whereas strains NCIMB 1900T and CIP 102762T highly likely are representatives of Vibrio natriegens.
