Bactéries pathogènes indigènes des eaux estuariennes: cas des vibrios. Revue bibliographique
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fouche, Dominique.
De nombreuses bactéries, peuplant habituellement les zones estuariennes, se révèlent être de plus en plus fréquemment des agents de maladies dont les vecteurs principaux sont les coquillages et leur consommation par l'homme. Le présent travail synthétise l'état des connaissances sur les vibrios, en particulier Vibrio cholerae, Vibrio parahaemolyticus et Vibrio vulnificus, bactéries pour lesquelles il existe une  abondante littérature. L'écologie, le pouvoir pathogène et les milieux de culture les plus couramment utilisés en vue de leur détection sont présentés. Enfin, leur interaction avec les mollusques bivalves, leur survie dans ceux-ci et le problème de l'épuration conséquente de ces derniers sont abordés.

Effects of temperature abuse on survival ofVibrio vulnificus in oysters
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Murphy, S; Oliver, J.
Of the several bacterial diseases which may result from consumption of shellfish, those caused by marine bacteria of the genus Vibrio are the most abundant. In the United States, up to 10,000 non-fatal cases per year are estimated to be caused by the various members of this genus. More than 95% of all deaths in the United States which result from seafood consumption are caused by a single bacterium, Vibrio vulnificus. The bacterium is a normal inhabitant of estuarine waters, and occurs naturally in especially high numbers in molluscan shellfish. Infections following consuption of raw or undercooked shellfish, especially oysters, result in fatality rates of over 60%. Because most oysters in the United States are transported large distances before marketing,...

Detection of cytotoxin-hemolysin mRNA in nonculturable populations of environmental and clinical Vibrio vulnificus strains in artificial seawater
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Fischer Le Saux, Marion; Hervio Heath, Dominique; Loaec, Solen; Colwell, Rita; Pommepuy, Monique.
The objective of this study was to develop a molecular detection method that better estimates the potential risk associated with the presence of Vibrio vulnificus. For that purpose, we applied seminested reverse transcription-PCR (RT-PCR) to viable but nonculturable (VBNC) populations of V. vulnificus and targeted the cytotoxin-hemolysin virulence gene vvhA. Three strains, two environmental, IF Vv10 and IF Vv18, and one clinical, C7184, were used in this study. Artificial seawater, inoculated with mid-log-phase cells, was maintained at 4degreesC. VBNC cells resulted after 3, 6, and 14 days for C7184, IF Vv18, and IF Vv10, respectively. Our data indicate that seminested RT-PCR is sensitive for the detection of vvhA mRNA in artificial seawater when...

Real-Time PCR optimization to identify environmental Vibrio spp. strains
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Tall, Amadou; Teillon, Anna; Boisset, Claire; Delesmont, R.; Touron-bodilis, A.; Hervio-heath, Dominique.
Aims: To identify Vibrio vulnificus, Vibrio cholerae and Vibrio alginolyticus using standardized DNA extraction method and real-time PCR assays, among a large number of bacterial strains isolated from marine environment. Methods and Results: Methods for DNA extraction and real-time PCR were standardized to identify a large number of Vibrio spp. strains isolated through regular collection campaigns of environmental samples. Three real-time PCR assays were developed from a multiplex PCR, targeting V. vulnificus, V. cholerae and V. alginolyticus on the dnaJ gene. After testing their specificity, these systems were applied for the identification of 961 strains isolated at 22°C (446 strains) and 37°C (515 strains) in September 2009. The predominance of V....

Effect of ionizing radiation onVibrio bacteria in Crassostrea virginica (American oyster)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Eberiel, D; Dooley, K; Langton, L; Malleth, J.
The presence of Vibrio bacteria in raw shellfish poses a significant health hazard to the consuming public. These human pathogens are natural, seasonal components of the microbial flora of shellfish which can result in primary septicemic or diarrheal fatal infections. Existing shellfish depuration neither targets nor eliminates the Vibrio bacteria. For this reason, additional purification processes are necessary. In this study, the effect of low dose gamma radiation on the inactivation ofVibrio cholerae (01 and non 01) and vulnificus is investigated. Log decrement (D10) values ranging only to a high of 0.09 KGy in the Vibrio strains support the hypothesis that food irradiation technology can provide an additional effective and efficient shellfish...

Oyster Demand Adjustments to Counter-Information and Source Treatments in Response to Vibrio vulnificus
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Morgan,   O. Ashton; Martin,   Gregory S.; Huth,   William L.
A web-based contingent behavior analysis was developed to quantify the effect of both negative and positive information treatments and post harvest processes on demand for oysters. Results from a panel model indicate that consumers of raw and cooked oysters behave differently after news of an oyster-related human mortality. While cooked oyster consumers take precautionary measures against risk, raw oyster consumers exhibit optimistic bias and increase their consumption level. Further, by varying the source of a counter-information treatment, we find that source credibility impacts behavior. Oyster consumers, and in particular, raw oyster consumers, are most responsive to information provided by a not-for- profit, nongovernmental organization. Finally, post...

BACKGROUND AND AIMS: Vibrio vulnificus causes an infectious disease that has extremely poor convalescence and leads to necrotic fasciitis. In this study, we sought to define the characteristic epidemiology of V. vulnificus infection and clarify its diagnosis at the global level. METHODS: Over a period of 10 years, we investigated the appearance of symptoms, underlying conditions, treatment, and mortality in 12 patients (eight men, four women; &gt;50 years old; average age, 66 years,) infected with V. vulnificus. RESULTS: The development of symptoms occurred primarily between June and September, a period during which seawater temperature rises and the prevalence of V. vulnificus increases. All patients had underlying diseases, and seven patients reported a...

Vibrio vulnificus infection in São Paulo, Brazil: case report and literature review
Provedor de dados: Brazilian Journal of Infectious Diseases
Autores: Araujo,Maria Rita Elmor de; Aquino,Caroline; Scaramal,Elton; Ciola,Claudete Sílvia; Schettino,Guilherme; Machado,Marcel Cerqueira Cesar.
Non cholera Vibrio may cause conjunctivitis, wound infection, gastroenteritis and serious sepsis. Transmission to men is through contact with skin, mucosa or wounds exposed to marine water, and consumption of certain barely cooked or raw seafood, more frequently in the summer. This is one of the first cases of severe infection related to Vibrio vulnificus described in Brazil. The patient was an old man, who ingested seafood in Guarujá, a seashore city near São Paulo, 3 days before hospitalization. He was admitted to the emergency room in an ill state with septic shock. On 2 sets of blood culture a highly virulent microorganism was isolated, Vibrio vulnificus, which leads to sepsis and frequently to death in susceptible patients. The objective of this...
