Vibrio parahaemolyticusis a Gram-negative halophilic bacterium that causes food-borne gastroenteritis in humans who consumeV. parahaemolyticus-contaminated seafood.The FORC_023 strain was isolated from raw fish storage water, containing live fish at a sashimi restaurant. Here, we aimed to sequence and characterize the genome of the FORC_023 strain. The genome of the FORC_023 strain showed two circular chromosomes, which contained 4227 open reading frames (ORFs), 131 tRNA genes and 37 rRNA genes. Although the genome of FORC_023 did not include major virulence genes, such as genes encoding thermostable direct hemolysin (TDH) and TDH-related hemolysin (TRH), it contained genes encoding other hemolysins, secretion systems, iron uptake-related proteins and severalV. parahaemolyticusislands. The highest average nucleotide identity value was obtained between the FORC_023 strain and UCM-V493 (CP007004-6). Comparative genomic analysis of FORC_023 with UCM-V493 revealed that FORC_023 carried an additional genomic region encoding virulence factors, such as repeats-in-toxin and type II secretion factors. Furthermore,in vitrocytotoxicity testing showed that FORC_023 exhibited a high level of cytotoxicity toward INT-407 human epithelial cells. These results suggested that the FORC_023 strain may be a food-borne pathogen.© FEMS 2016. All rights reserved. For permissions, please e-mail: [email protected]
