Vibrio galatheae sp. nov., a member of the family Vibrionaceae isolated from a mussel

Int J Syst Evol Microbiol. 2016 Jan;66(1):347-352. doi: 10.1099/ijsem.0.000723. Epub 2015 Oct 28.


Based on genetic, chemotaxonomic and phenotypic characteristics, a novel species belonging to the genus Vibrio is described. The facultatively anaerobic strain S2757T was isolated from a mussel collected in the Solomon Sea (Solomon Islands). Phylogenetic analyses based on sequences of 16S rRNA and fur genes indicated affiliation of the strain to a novel species. This observation was supported by a multilocus sequence analysis including sequences of the housekeeping genes 16S rRNA, gyrB, pyrH, recA and topA. In silico DNA-DNA hybridization and average nucleotide identity values comparing the genomic sequence of strain S2757T with those of closely related type strains were lower than 23 and 82 %, respectively. The DNA G+C content of the strain was 45.3 mol%. Phenotypic and chemotaxonomic analyses clearly differentiated the strain from other Vibrio species. Hence, strain S2757T should be considered to represent a novel species of the genus Vibrio, for which the name Vibrio galatheae sp. nov. is proposed. The type strain is S2757T ( = DSM 100497T = LMG 28895T).
