A total of 1,007 Vibrio infections were reported to the Infectious Disease Epidemiology Department at the Louisiana Office of Public Heath, between 1980 and 2005. The most common were Vibrio vulnificus (257 infections), Vibrio parahemolyticus (249 infections), and Vibrio cholerae non O1 (200 cases). Other species were much less common. Vibrio vulnificus infections, which are associated with con...

In 2007, diseases caused by Vibrio vulnificus and other Vibrio species became nationally notifiable in the United States because of the potential severity of bloodstream infections. Direct contact of open wound with seawater and the ingestion of contaminated oysters are the principal modes of transmission. Presently, no clear environmental predictors of oyster contamination are known. This stud...

quorum sensing controls the luminescence of vibrio fischeri through the transcriptional activator luxr and the specific autoinducer signal produced by luxi. amino acid sequences of these two genes were analyzed using bioinformatics tools. luxi consists of 193 amino acids and appears to contain five α-helices and six ß-sheets when analyzed by sspro8. luxi belongs to the autoinducer synthetase fa...

conclusions chlorine-stressed cells of v. parahaemolyticus were more susceptible to adverse conditions than the non-stressed ones. pathogenic and non-pathogenic strains showed the same survival characteristics under the adverse conditions. these results should be considered in the development of food preservation measures. results findings of the current study revealed that the normal cells of ...

AIMS To develop a multiplex PCR targeting the gyrB and pntA genes for Vibrio species differentiation. METHODS AND RESULTS Four pairs of primers targeting gyrB gene of Vibrios at genus level and pntA gene of Vibrio cholerae, Vibrio parahaemolyticus, Vibrio vulnificus were designed. This PCR method precisely identified 250 Vibrio species and demonstrated sensitivity in the range of 4 x 10(4) CF...

Vibrio vulnificus, which is, like Vibrio cholerae and Vibrio parahaemolyticus, a pathogen of humankind, is a Gram-negative, curved, motile, and rod-shaped bacterium [corrected] Here, we present the draft genome sequence of the type strain, ATCC 27562, which was the first isolated Vibrio vulnificus strain.

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.

a total of 116 marine fishes and sediments were collected from persian gulf shore near bushehr in order to isolate vibrio species. after culturing on thiosulphate- cirate- bile salts- sucrose and with biochemical tests, 30 isolates showed vibrio characteristics which were categorized in 7 vibrio species, v. anguillarum, v. alginalyticus, v. harveyi, v. vulnfiicus, v. ordalii, v. carchariae and ...

Different species of bacteria were tested for production of extracellular autoinducer-like activities that could stimulate the expression of the luminescence genes in Vibrio harveyi. Several species of bacteria, including the pathogens Vibrio cholerae and Vibrio parahaemolyticus, were found to produce such activities. Possible physiological roles for the two V. harveyi detection-response system...
