Historically, methods used to identify Vibrio vulnificus in environmental samples have been inadequate because isolation and identification procedures are time-consuming and fail to separate V. vulnificus from other bacterial species. We describe an enzyme immunoassay (EIA) and culture techniques which identified V. vulnificus in seawater, sediment, and oysters. The EIA used monoclonal antibody...
During the unusually warm summer in Denmark in 1994, 11 clinical cases of Vibrio vulnificus infection were reported. These reports initiated an investigation of the occurrence of V. vulnificus biotypes in Danish marine environments. Samples of coastal water, sediment, shellfish, and wild fish were analyzed by preenrichment in alkaline peptone water amended with polymyxin B (2.0 x 10(4) U/liter)...
Vibrio vulnificus is an opportunistic pathogen of humans that has the capability of causing rare, yet devastating disease. The bacteria are naturally present in estuarine environments and frequently contaminate seafoods. Within days of consuming uncooked, contaminated seafood, predisposed individuals can succumb to sepsis. Additionally, in otherwise healthy people, V. vulnificus causes wound in...
Vibrio are a genus of marine bacteria that have substantial environmental and human health importance, and there is evidence that their impact may be increasing as a consequence of changing environmental conditions. We investigated the abundance and composition of the Vibrio community within the Sydney Harbour estuary, one of the most densely populated coastal areas in Australia, and a region c...
Vibrios and other enteric pathogens can be found in wastewater effluents of a healthy population. We assessed the prevalence of three non-cholerae vibrios in wastewater effluents of 14 wastewater treatment plants (WWTP) in Chris Hani and Amathole district municipalities in the Eastern Cape Province of South Africa for a period of 12 months. With the exception of WWTP10 where presumptive vibrios...
The population of Vibrios in diseased Penaeus monodon collected from culture ponds situated at Uran, Maharashtra (west coast of India) was studied. All animals collected were associated with more than one Vibrio species. Bacterial identification based on morphological and biochemical characteristics showed that four groups of Vibrios were present in shrimp hepatopancreas namely Vibrio parahaemo...
Vibrio vulnificus is a bacterium responsible for severe gastroenteritis, sepsis and wound infections. Gastroenteritis and sepsis are commonly associated with the consumption of raw oysters, whereas wound infection is often associated with the handling of contaminated fish. Although classical virulence factors of this emerging pathogen are well characterised, there remains a paucity of knowledge...
Vibrio vulnificus is a bacterial contaminant of shellfish and causes highly lethal sepsis and destructive wound infections. A definitive identification of virulence factors using the molecular version of Koch's postulates has been hindered because of difficulties in performing molecular genetic analysis of this opportunistic pathogen. For example, conjugation is required to introduce plasmid DN...
A selective medium (VVM) and a specific 16S rRNA gene (rDNA) probe (V3VV) for the detection of Vibrio vulnificus were developed. The medium contains D-(+)-cellobiose as the main carbon source and electrolytes (MgCl(2)-6H(2)O and KCl), which stimulate bacterial growth. Polymyxin B, colistin, and moderate alkalinity and salinity provide selectivity properties. V. vulnificus grows on VVM as flat, ...
Vibrio spp. are gram-negative, facultative anaerobic, non-spore-forming bacilli which are oxidase positive and halophilic bacteria widely spread in seaand brackwater worldwide. The genus Vibrio includes several foodborne pathogens which cause a spectrum of clinical conditions including septicaemia, cholera and milder forms of gastroenteritis. The species most commonly associated with foodborne ...
