Vibrio intestinalis sp. nov., isolated from intestine of seahorse

A novel Gram-stain-negative, catalase- and oxidase-positive, facultatively anaerobic, and rod-shaped motile bacterial strain, designated as YLB-11 T , was isolated from seahorse intestine. The 16S rRNA gene sequencing analysis showed that YLB-11 T was most closely related Vibrio mytili LMG 19157 T (98.9 % nucleotide sequence identity). Phylogenetic analysis placed strain YLB-11 T within the genus Vibrio . The major cellular fatty acids were summed feature 3 (C 16: 1 ω 6 c /C 16 : 1 ω 7 c , 36.4 %), C 16 : 0 (19.1 %) and summed feature 8 (C 18:1 ω 6 c /C 18:1 ω 7 c , 12.3 %). The DNA G+C content of YLB-11 T was 44.7 mol %. The in silico DNA–DNA hybridization and average nucleotide identity values for whole-genome sequence comparisons between YLB-11 T and related species were clearly below the thresholds used for the delineation of a novel species. Therefore, YLB-11 T is considered to represent novel species of the genus Vibrio , for which the name Vibrio intestinalis sp. nov. is proposed. The type strain is YLB-11 T (=MCCC 1A17441 T =KCTC 72604 T ).
