Vibrio, a diverse genus of aquatic bacteria, currently includes 72 species, 12 of which occur in human clinical samples. Of these 12, three species--Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus-account for the majority of Vibrio infections in humans. Rapid and accurate identification of Vibrio species has been problematic because phenotypic characteristics are variable within...

Vibrio vulnificus was found to produce a chemical that induced the expression of Vibrio fischeri lux genes. Electron spray ionization-mass spectrometry and 1H nuclear magnetic resonance analyses indicated that the compound was cyclo(L-Phe-L-Pro) (cFP). The compound was produced at a maximal level when cell cultures reached the onset of stationary phase. Sodium dodecyl sulfate-polyacrylamide gel...

vibrio species are the major seafood-borne bacteria that are frequently associated with the consumption of contaminated sea food. a total of 113 samples including 58 fish and 55 shrimps were studied for the possible contamination with vibrio species. a biochemical protocol was applied for the identification of the vibrio isolates and polymerase chain reaction (pcr) was carried out to confirm th...

Necrotising fasciitis is a rapidly progressing necrotising process involving subcutaneous tissue and fascia but sparing muscles, and is accompanied by severe systemic toxicity.1 2The syndrome is often caused by group A streptococci,' 3 but it is now recognised that other bacteria may be involved, usually in mixed culture. Organisms that have been implicated include a variety of anaerobes, enter...

Vibrio vulnificus biotype 3 is an emerging pathogen isolated from cultures of skin and blood samples obtained from patients who were directly injured by the fins of tilapia fish bred in artificial ponds. We describe a patient infected with this pathogen after being punctured by a wire. Meticulous anamnestic investigation demonstrated for the first time that this pathogen can survive on the skin...

Vibrio vulnificus is a seafood-associated pathogen that causes severe wound and intestinal infections. Biotype 3 of V. vulnificus emerged in 1996 as the cause of an Israeli outbreak associated with the handling of infected tilapia. Here, we describe the whole-genome sequence of the ATCC biotype 3 clinical isolate BAA87 (CDC9530-96).

The aim of this research was to study the occurrence of Vibrio spp., Aeromonas hydrophila, Escherichia coli and Campylobacter spp. in crayfish from Azerbaijan Province using culture method and PCR assay. A total of 55 isolates were collected from 97 studied samples. Vibrio spp., A. hydrophila, E. coli and Campylobacter spp. were detected in 26 samples (26.8%), 12 samples (12.3%), 15 samples (15...

Numerous secreted virulence factors have been proposed to account for the fulminating and destructive nature of Vibrio vulnificus infections. A mutant of V. vulnificus that exhibited less cytotoxicity to INT-407 human intestinal epithelial cells was screened from a library of mutants constructed by random transposon mutagenesis. A transposon-tagging method was used to identify and clone an open...

One of the most common bacteria in tropical to subtropical seawater, Vibrio vulnificus is an invasive, gram-negative bacillus and recognized as a cause of fulminant primary septicemia, wound infections and gastrointestinal disorders. In the United States, it is found predominantly along the coastlines of those states that border the Gulf of Mexico, but has also been isolated from areas in New E...
