Description:
Vibrio parahaemolyticus is a Gram-negative, motile, nonspore-forming pathogen that causes foodborne illness associated with the consumption of contaminated seafoods. Although many cases of foodborne outbreaks caused by V. parahaemolyticus have been reported, the genomes of only five strains have been completely sequenced and analyzed using bioinformatics. In order to characterize overall virulence factors and pathogenesis of V. parahaemolyticus associated with foodborne outbreak in South Korea, a new strain FORC_008 was isolated from flounder fish and its genome was completely sequenced. The genomic analysis revealed that the genome of FORC_008 consists of two circular DNA chromosomes of 3266 132 bp (chromosome I) and 1772 036 bp (chromosome II) with a GC content of 45.36% and 45.53%, respectively. The entire genome contains 4494 predicted open reading frames, 129 tRNAs and 31 rRNA genes. While the strain FORC_008 does not have genes encoding thermostable direct hemolysin (TDH) and TDH-related hemolysin (TRH), its genome encodes many other virulence factors including hemolysins, pathogenesis-associated secretion systems and iron acquisition systems, suggesting that it may be a potential pathogen. This report provides an extended understanding on V. parahaemolyticus in genomic level and would be helpful for rapid detection, epidemiological investigation and prevention of foodborne outbreak in South Korea.
