Three Gram-negative, small, motile, rod-shaped bacteria were isolated from Artemia sp. and sea water in Barcelona, Spain, during 1990 and 1991. They were fermentative, oxidase-positive, sensitive to vibriostatic agent O/129, arginine dihydrolase-positive, lysine and ornithine decarboxylase-negative and grew in the absence of NaCl. They differed from phenotypically related species by their ability to grow at 4 °C and utilize L-rhamnose. Cloning of the 16S rRNA gene of the type strain produced two different 16S rRNA gene sequences, which differed by 15 bases (0·99 %); comparison of these sequences with those deposited in GenBank showed close relationships with Vibrio proteolyticus (97·6 % similarity), Vibrio diazotrophicus (97·9 %), Vibrio campbellii (96·8 %) and Vibrio alginolyticus (96·8 %), among others. DNADNA hybridization levels with the closest phylogenetically related Vibrio species were <26·4 %. Sufficient evidence is provided to support the identity of the three strains analysed as members of a novel species of the genus Vibrio, for which the name Vibrio hispanicus sp. nov. is proposed, with the type strain LMG 13240T (=CAIM 525T=VIB 213T).
Published online ahead of print on 22 August 2003 as DOI 10.1099/ijs.0.02775-0.
The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of LMG 13240T clones 1 and 2 are AY254039 and AY254040, respectively.
A graph showing growth of Vibrio hispanicus sp. nov. at different NaCl concentrations is available as supplementary material in IJSEM Online.
