Background Vibrio vulnificus, an opportunistic pathogen, is the causative agent of life-threatening septicemia and severe wound infections. However, the pathogenicity and virulence factors of V. vulnificus are not fully understood. Here we report the complete genome sequence of V. vulnificus VV2014DJH, which was isolated from a death case. Results The genome of the V. vulnificus VV2014DJH con...

An efficient electroporation procedure for Vibrio vulnificus was designed using the new cloning vector pVv3 (3,107 bp). Transformation efficiencies up to 2 × 10(6) transformants per μg DNA were achieved. The vector stably replicated in both V. vulnificus and Escherichia coli and was also successfully introduced into Vibrio parahaemolyticus and Vibrio cholerae. To demonstrate the suitability of ...

Vibrio parahaemolyticus and Vibrio vulnificus, which are native to estuaries globally, are agents of seafood-borne or wound infections, both potentially fatal. Like all vibrios autochthonous to coastal regions, their abundance varies with changes in environmental parameters. Sea surface temperature (SST), sea surface height (SSH), and chlorophyll have been shown to be predictors of zooplankton ...

Eleven Vibrio vulnificus (lactose-positive vibrio) strains were less susceptible to the bactericidal activity of normal human serum or serum treated with magnesium-ethyleneglycol-bis (beta-aminoethyl ether)-N,N'-tetraacetic acid than were six Vibrio parahaemolyticus strains.

BACKGROUND Vibrio vulnificus is an important pathogen which can cause serious infections in humans. Yet, there is limited knowledge on its virulence factors and the question whether temperate phages might be involved in pathogenicity, as is the case with V. cholerae. Thus far, only two phages (SSP002 and VvAW1) infecting V. vulnificus have been genetically characterized. These phages were isola...

The differential and selective sodium dodecyl sulfate-polymyxin B-sucrose medium (SPS) of Kitaura et al. (T. Kitaura, S. Doke, I. Azuma, M. Imaida, K. Miyano, K. Harada, and E. Yabuuchii, FEMS Microbiol. Lett. 17:205-209, 1983), which highlights alkylsulfatase activity, was evaluated for its potential use in the direct isolation and enumeration of Vibrio vulnificus from shellfish. V. vulnificus...

Vibrio vulnificus (V. vulnificus), a Gram-negative marine bacterium, can cause life-threatening primary septicemia, especially in patients with liver diseases. How V. vulnificus affects the liver and how it acts on macrophages are not well understood. In this report, we demonstrated that V. vulnificus infection causes a strong inflammatory response, marked expansion of liver-resident macrophage...

A quadruplex loop-mediated isothermal amplification (LAMP) method was developed to detect four Vibrio species, including Vibrio ichthyoenteri, Vibrio parahaemolyticus, Vibrio scophthalmi, and Vibrio vulnificus, simultaneously. Four sets of species-specific primers were designed with different restriction sites contained in the inner primers. The quadruplex LAMP method could distinguish four Vib...

The genus Vibrio is a member of the family Vibrionaceae, and among their disease-causing species, Vibrio vulnificus, a lactose-positive gram-negative bacillus, is one of the most virulent pathogen of the noncholerae vibrios. We describe the case of a 39-year-old male patient, who was using immunosuppressive therapy, admitted to the hospital for liver transplantation. Twelve hours later, the pat...

To determine if a storm event (i.e., high winds, large volumes of precipitation) could alter concentrations of Vibrio vulnificus and V. parahaemolyticus in aquacultured oysters (Crassostrea virginica) and associated surface water and sediment, this study followed a sampling timeline before and after Hurricane Irene impacted the Chesapeake Bay estuary in late August 2011. Aquacultured oysters we...
