One Perkinsus species may hide another: characterization of Perkinsus species present in clam production areas of France
Provedor de dados: 5
Autores: Arzul, Isabelle; Chollet, Bruno; Michel, Justine; Robert, Maeva; Garcia, Celine; Joly, Jean-pierre; Francois, Cyrille; Miossec, Laurence.
Although clam populations in France are known to be infected with protozoans of the genus Perkinsus, no molecular characterization was previously performed on these parasites. Considering that several members of this genus have been associated with mortalities of molluscs worldwide, a study was undertaken in order to characterize these parasites in France. For that purpose, clams, Ruditapes philippinarum and R. decussatus, collected from different production areas and found to be infected with Perkinsus sp. in thioglycolate culture medium, were selected for PCR-RFLP tests and sequencing. Perkinsus olseni was detected in all the investigated areas and results also suggested the presence of P. chesapeaki in Leucate, a lagoon on the Mediterranean coast and in...

Three-year study to assess human enteric viruses in shellfish
Provedor de dados: 5
Autores: Le Guyader, Soizick; Haugarreau, Larissa; Miossec, Laurence; Dubois, Eric; Pommepuy, Monique.
The main pathogenic enteric viruses able to persist in the environment, such as hepatitis A virus (HAV), Norwalk-like virus (NLV), enterovirus (EV), rotavirus (RV), and astrovirus (AV), were detected by reverse transcription-PCR and hybridization in shellfish during a 3-year study. Oyster samples (n = 108), occasionally containing bacteria, were less frequently contaminated, showing positivity for AV (17%), NLV (23%), EV (19%), and RV (27%), whereas mussel samples, collected in areas routinely impacted by human sewage, were more highly contaminated: AV (50%), HAV (13%), NLV (35%), EV (45%), and RV (52%). Sequences obtained from HAV and NLV amplicons shelved a great variety of strains, especially for NLV (strains close to Mexico, Snow Mountain Agent, or...

The Ifremer Repamo network (REseau de PAthologie des MOllusques) is the national surveillance network in charge of monitoring marine mollusc health on French coastlines. It is commissioned to enforce the official regulations and to provide a public service, under the supervision of the competent authority (DGAL Veterinary Directorate) in the Ministry.of Agriculture and Fisheries. Its goals are to prevent the introduction and the dissemination of infectious agents, in particular pathogens involved in reportable diseases, and to monitor the changes in the pathogens already present on the French coasts.

Created in 1986, the REPAMO network (Network of mollusc pathology), is a national zoosanitary surveillance network of shellfish health status along the French coasts. Its activities are in keeping with two European Directives, 91 /67/EEC and 95/70/EC and are a patt of the institutional tasks ofIfremer. The aims of the network are to prevent the introduction and spread of exotic pathogens and to survey the evolution of notifiable pathogens already present in France. The network focused on the survey of listed diseases (bonamiosis and marteiliosis of flat oyster) in two areas under agreement process (Banc de Granville and zone X). In 2004, no sample couId be analysed to these two areas because of the difficulty to obtain flat oysters (sparse oyster beds,...

Validity of Escherichia coli, enterovirus, and F-specific RNA bacteriophages as indicators of viral shellfish contamination
Provedor de dados: 5
Autores: Miossec, Laurence; Le Guyader, Soizick; Pelletier, Dominique; Haugarreau, Larissa; Caprais, Marie-paule; Pommepuy, Monique.
The sanitary classification of harvesting areas for bivalve mollusks in France is based on the level of Escherichia Coli contamination detected in shellfish meat, as defined in EC Directive 91/492 EEC. However, outbreaks of gastroenteritis or hepatitis after consumption of shellfish meeting current bacteriological standards suggest that E. coli is a poor indicator of viral contamination. The purpose of this study was to assess the adequacy of enterovirus and F-specific RNA bacteriophages as new indicators of human enteric viruses. Shellfish were sampled over a 37-mo period to characterize microbial contamination in two coastal areas subjected to different sewage contamination inputs. Contamination by E. coli, F-specific RNA bacteriophages (F+ RNA) and...

Autores: Belin, Catherine; Miossec, Laurence; Joanny, Michel; Claisse, Didier.
La salubrité des produits livrés au consommateur est un des objectifs des programmes de surveillance de la qualité du milieu marin. Trois types de contaminants peuvent altérer la qualité des produits : les micro-organismes pathogènes, les micro-polluants chimiques et les biotoxines sécrétées par certaines espèces phytoplanctoniques. Une surveillance de la salubrité des mollusques bivalves susceptibles d'être affectés par ces trois types de contamination est assurée au plan national dans le cadre du Réseau Microbiologique (REMI), du Réseau National d'Observation de la qualité du milieu marin (RNO) et du Réseau Phytoplanctonique (REPHY).

Provedor de dados: 5
Autores: Miossec, Laurence; Arzul, Isabelle; Garcia, Celine; Soudant, Philippe; Francois, Cyrille; Leite, R. B.; Cancela, M. L.; De Blas, I.
Infectious diseases in exploited shellfish population cause economical problems world-wide. The characteristics of the disease in the population -i.e. origin, frequency, distribution, development- need to be well known to set up appropriate measures for protection and restoration of shellfish population health. The investigation of disease in a population is the basis of epidemiology. Quantitative investigations include studies, survey, surveillance with specific sampling strategies according to the objectives. European clams (Ruditapes decussatus) and Manila clams (Ruditapes philippinarum), two commercially valuable species, are infected by the protozoan Perkinsus olseni. This pathogen has been associated with epizootic outbreaks involving in heavy...

Possible relation between a winter epidemic of acute gastroenteritis in France and viral contamination of shellfish
Provedor de dados: 5
Autores: Miossec, Laurence; Le Guyader, Soizick; Haugarreau, Larissa; Comps, Marie-annick; Pommepuy, Monique.
Several outbreaks of gastroenteritis related to the consumption of shellfish (frequently eaten raw) have been reported in different parts of the world. In Europe, hum an calicivirus infections may have been involved in winter outbreaks in recent years, although there is little evidence confirming such viral contamination in shellfish. This study presents the first results of a field survey on viral contamination in two shelllish harvesting areas along the French Mediterranean coast. The first, consisting mainly of oyster beds, was c1assified in category A, as determined by fecal coliform counts in shellfish (European Community Directive 91/492), and the second, a mussel bed, was c1assified in category C. Shelllish samples were collected monthly between...

Abnormal mortality outbreaks occurred in the majority of Pacific oyster (Crassostrea gigas) producing areas in France in 2008 during the summer period. These outbreaks were usually sudden and severe (up to 100%) and affected essentially spat (oysters less than 1 year-old) and juveniles (12 to 18 month-old oysters). Crassostrea gigas was the single affected species Mortality outbreaks were first observed from mid May to mid June in Brittany, Vendée, Charente Maritime and Mediterranean coast A second episode of massive mortality events was reported at the end of June and the beginning of July. All oyster production sites were affected except some particular locations including Arcachon Bay and Brittany. Mortality occurred latter in Arcachon Bay in August....

Molecular characterization of parasites of the genus Perkinsus present in clams from French producing areas
Provedor de dados: 5
Autores: Arzul, Isabelle; Michel, Justine; Chollet, Bruno; Robert, Maeva; Miossec, Laurence; Garcia, Celine; Francois, Cyrille.
Production of clams is the third most important bivalve production in France and was estimated at 3400 metric tons in 2001 among which 60% came from aquaculture and 40% from fisheries. Surveillance of clam diseases mainly relies on histology and thioglycolate culture, two techniques allowing detection of parasites of the genus Perkinsus but not specific enough to determine the parasite species. Based on a previous study aiming at estimating distribution and prevalence of perkinsosis in France, we selected 34 infected clams from 4 different producing areas in order to characterize the parasite species. Molecular characterization was done by PCR-RFLP targeting the ITS region as described by Abollo et al. (2006). 16 PCR products were cloned and 10 to 20...

Autores: Miossec, Laurence.
Le besoin, sans cesse accru, des pays industrialisés, s'appuyant essentiellement sur une technologie à base de pétrole, a conduit à une demande de plus en plus importante d'hydrocarbures. Les chiffres le prouvent puisque la production mondiale a été multipliée par 11 entre 1938 et 1878. Ou fait de la distance entre pays producteurs et pays consommateurs, le transport s'effectue essentiellement par voie maritime; aussi, pour la même période, la flotte pétrolière mondiale a-t-elle été multipliée par 21 (BERTRAND, 1979). Les grands ports pétroliers européens se situant en Manche ou Mer du Nord, l'Atlantique Nord est le siège d'un trafic important. De ce fait, l'Europe atlantique est devenue une zone très vulnérable et la plus touchée par les pollutions...

Bonamia ostreae and Ostrea edulis : a stable host-parasite system in France?
Provedor de dados: 5
Autores: Arzul, Isabelle; Miossec, Laurence; Blanchet, Estelle; Garcia, Celine; Francois, Cyrille; Joly, Jean-pierre.
Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting flat oysters Ostrea edulis. After its first description in June 1979 in L'Ile Tudy, Brittany, the parasite rapidly spread to all French oyster farming areas and in other European countries through transfers of live molluscs. Bonamiosis and marteiliosis, another protozoan disease appeared in the seventies, drastically reduced the French flat oyster production from 20 000 tonnes in 1970 to less than 2000 tonnes after 1981. In 2001, about 1650 t of flat oysters were marketed in France. The production is restricted to several areas specialised in reproduction, growth and/or marketing, and depends on transfers of animals. Most important production...

REPAMO: a surveillance tool for mollusc health
Provedor de dados: 5
Autores: Francois, Cyrille; Garcia, Celine; Arzul, Isabelle; Joly, Jean-pierre; Miossec, Laurence; Chollet, Bruno; Ferrand, Sylvie; Robert, Maeva.
At the present time losses due to diseases are one of main factors limiting the aquaculture development. Unceasing increase of exchanges between different countries favours the risk of introduction and propagation of new pathogen agents. At the beginning of the 90’s the European Union laid the surveillance of mollusc health inside each Member State in order to protect the safety of exchanges. Indeed few measures are available to protect molluscs from diseases. Only the prophylactic approach is possible; this approach is based on a zoosanitary surveillance of mollusc populations and/or a development of resistant populations against some diseases. Created in 1986, the French network for surveillance and monitoring of mollusc health (REPAMO) ensures the...

Les microorganismes, bactéries et virus d'origine entérique, sont abondants dans les rejets urbains. Si la charge bactériologique contenue dans les eaux usées est notablement réduite lors des traitements appliqués dans les stations d'épurations, de nombreux microorganismes persistent et sont rejetés avec les eaux épurées dans le milieu récepteur, en rivière ou directement en mer. Le développement de méthodes analytiques basées sur la biologie moléculaire a permis récemment la détection de virus entériques non cultivables dans les échantillons de l'environnement, tels que les entérovirus, le virus de l'hépatite A, les calicivirus, les astrovirus et les rotavirus. En France, les données publiées sur la présence de ces virus entériques, détectés par RTPCR,...

Development of a generic decision-support tool for identifying potentially invasive aquatic taxa: AS-ISK
Provedor de dados: 5
Autores: Copp, Gordon H.; Vilizzi, Lorenzo; Tidbury, Hannah; Stebbing, Paul D.; Trakan, Ali Serham; Miossec, Laurence; Goulletquer, Philippe.
Electronic decision-support tools are now an essential component of government strate gies to battle non-native species, with taxon-specific, paper-based risk analysis schemes often being replaced by taxon-generic tools. This study reports on the development of a decision-support tool for aquatic species, the Aquatic Species Invasiveness Screening Kit (AS-ISK), which replaces five taxon-specific toolkits for amphibians, freshwater and marine fish and invertebrates (FISK, MFISK, FI-ISK, MI-ISK, Amph-ISK). Adapted from Pheloung et al.’s. Weed Risk Assessment (WRA), the “-ISK” toolkits were also “self-automated workbooks” in Excel® VisualBasic® architecture of the ’WRA. In creating AS-ISK, we incorporated the conceptual approach (questions and guidance) of...

An index CCO (cover, characteristic species, opportunistic species) has been developed for the implementation of the European Water Framework Directory (WFD) in coastal waters, using intertidal macroalgal communities as bio-indicator (Biological Quality Element). CCO is based on the calculation of three metrics corresponding to the global cover of macroalgal communities (metric 1), the number of characteristic species per topographic level/seaweed community (metric 2) and the cover of opportunistic species (metric 3). The final rating is obtained by pooling the scores of the three metrics. Results are given for 32 sites in 29 water bodies, grouped into four biogeographic regions along the Channel–Atlantic coasts of France. Over the six-year study, most of...

From November 1978 to January 1982, the author has studied the effects of Amoco Cadiz oil spill on plaice (Pleuronectes platessa) reproduction, main species of flat fish of the aber Wrac'h and aber Benoit. Serious alterations of the function were observed in females. Examining the gonado-somatic ratio has revealed some anomalies in the reproductive process. Study of ovary histology has shown large cytologic modifications. Some hypothesis have been retained: oil action in situ, use of lipidic reserves for another aim than reproduction, and hormonal perturbations.

Since its molecular characterisation, Ostreid herpesvirus 1 (OsHV-1) has been regularly detected in Crassostrea gigas in France. Although its pathogenicity was demonstrated on larval stages, its involvement during mortality outbreaks at the juvenile stage was highly suspected but not evidenced. To investigate mortality outbreaks, the French National Network for Surveillance and Monitoring of Mollusc Health (REPAMO) carried out two surveys in juvenile C. gigas. The first survey lasted from 1998 to 2006 and was an epidemiological inquiry occurring when oyster farmers reported mortality outbreaks. The second survey, a longitudinal one, was set up in 1998 to complete the network observations on OsHV-1. Data analysis showed a specific pattern of mortality...

Développement d'une méthodologie de qualification de l'espace côtier. Application à la Façade Méditerranéenne
Provedor de dados: 5
Autores: Denis, Jacques; Miossec, Laurence.
Le milieu littoral est soumis à une forte influence de la part du milieu terrestre. Sa qualité, dont la tendance est à la dégradation, est l'objet de fortes préoccupations suscitées par la nécessité d'une gestion plus rigoureuse de la ressource Eau, dans l'ensemble de la zone côtière. L'évaluation même de la qualité du milieu littoral devient un élément clé dans ce processus de gestion, dit de l'amont par l'aval et demande, pour ce faire, un outil adapté capable de satisfaire cette exigence. Cet outil consiste en une méthodologie d'approche de l'espace côtier. Elle est à la fois globale, pour son échelle d'application à la façade méditerranéenne entière et intégrée, pour la prise en compte d'un ensemble de facteurs influants sur la qualité résultante.

Non-native aquatic animals introductions have driven disease emergence in Europe
Provedor de dados: 5
Autores: Peeler, Edmund J.; Oidtmann, Birgit C.; Midtlyng, Paul J.; Miossec, Laurence; Gozlan, Rodolphe E.
In this paper it is argued, using examples of disease emergence in aquatic animals in Europe, that the introduction of non-native species drives disease emergence by both extending the geographic range of parasites and pathogens and facilitating host-switching. Enteric red mouth disease and infectious haematopoietic necrosis of salmonids have extended their geographic range from North America to Europe with the import of live fish (Pimephales promelas) and rainbow trout eggs, respectively. Host-switching results in disease emergence when previously unidentified commensal organisms or known pathogen switch to new naïve hosts. The most serious endemic diseases of wild aquatic animals in Europe in recent years can be traced to the introduction of non-native...

For centuries human populations have moved live shellfish around the world for consumption or aquaculture purposes; being relayed from their area of origin for growout or sale. This is in contrast to the inadvertent anthropogenic spreading of species via e.g. ballast waters. There are inherent risks associated with transfer of shellfish including introducing of alien species, diseases, pests, bacteria and viruses associated with the translocated species in addition to the potential impact on genetic integrity and biodiversity of local stocks. Many examples of severe ecological impacts have been documented worldwide owing to the intentional or unintentional translocation of animals. It is therefore important to develop risk reduction methods which have not...

Alien species alert: Crassostrea gigas (Pacific oyster)
Provedor de dados: 5
Autores: Miossec, Laurence; Le Deuff, Rose-marie; Goulletquer, Philippe.
The Pacific oyster (Crassostrea gigas, Thunberg, 1793) is one of 20 species in the genus Crassostrea. Although native to the Japan/Korea region, C. gigas is a hardy species that has been introduced to a number of countries worldwide, including the US, Canada, the UK, France, Korea, China, New Zealand, Australia, South Africa, and South America, mainly for aquaculture purposes (Mann et al., 1991; Orensanz et al., 2002). As a result, C. gigas has become the leading species in world shellfish culture, with an estimated production of 4.6 million t in 2006 (FAO, 2008). Because C. gigas does not require additional food to sustain its growth, this species is relatively inexpensive and easy to produce. Its capacity to adapt to various environmental conditions and...

L’incertitude associée à une mesure a pour origine d’une part la variabilité environnementale et d’autre part l’ensemble du processus d’acquisition depuis le prélèvement jusqu’à la saisie de la donnée dans une base. L’estimation de l'ensemble de cette variabilité est un exercice complexe à réaliser dans le cadre d’un plan d’expérience. En revanche, les séries temporelles présentent la caractéristique d’intégrer toutes les variabilités et ainsi l’analyse de ces séries en terme de signal et bruit doit permettre de quantifier l’amplitude des incertitudes. Toutefois, les séries temporelles d’observation présentent un ensemble de caractéristiques les rendant difficiles à analyser. Les modèles linaires dynamiques constituent une approche adaptée à ces données...

The Pacific oyster Crassostrea gigas: from an introduced species for aquaculture to an invasive species for the ecosystem Miossec L. and Goulletquer Ph. The Pacific oyster Crassostrea gigas has been introduced worldwide for aquaculture purposes since the beginning of the last century. In most of the countries the species established broadly, emphasizing its ability to adapt to a wide range of environmental conditions. In Europe the Pacific oyster was massively introduced in the 1970s especially into France after mass mortalities of the Portuguese oyster Crassostrea angulata affected by a viral disease. Good environmental conditions in some French areas on the Atlantic coast induced successful recruitments in the following years. The population became...

Autores: Miossec, Laurence; Girard, Sophie; Czerwinski, N.
The first national census concerning shellfish culture in France was carried out in 2002. The main purpose was to provide accurate and comprehensive information on the number and structure of the companies using an in depth review of production factors (leases, plants, equipment's, labour and qualifications), and a survey of cultural practices up to the market level. Moreover, the census aimed to quantify the bivalve sales dedicated to consumption and to measure the livestock transfers among rearing shellfish production areas at different developmental stages: spat, intermediate products and fully grown marketable products. The French oyster production reached 109 000 metric tons in 2001. The main production was observed in Poitou-Charentes region...

At the present time losses due to diseases are one of main factors limiting the aquaculture development. Unceasing increase of exchanges between different countries favours the risk of introduction and propagation of new pathogen agents. At the beginning of the 90's the European Union laid the surveillance of mollusc health inside each Member State in order to protect the safety of exchanges. Indeed few measures are available to protect molluscs from diseases. Only the prophylactic approach is possible; this approach is based on a zoosanitary surveillance of mollusc populations and/or a development of resistant populations against some diseases. Created in 1986, the French network for surveillance and monitoring of mollusc health (REPAMO) ensures the...

La chloration des effluents urbains avant rejet en mer
Provedor de dados: 5
Autores: Abarnou, Alain; Guillaud, Jean-francois; Miossec, Laurence; Batt, Agnes.
Chlorination of wastewater prior to effluent discharge into the sea is used as disinfecting treatment to preserve salubrity of the coastal marine environment wich is necessary for such activities as shellfish-farming and nautical sports. The disinfecting capacity of chlorine results from its oxydizing property which gives rise to various chemical reactions with constituents present in wastes. ln wastewaters, highly loaded with organic matter and ammonia, monochloramine is the main active chlorine species. Due to organic matter oxydation, thèse active chlorine species rapidly disappear by transformation into non toxic chloride. However, a very sm ail part of the initial chlorine dose can be found as stable and toxic chloroorganics. Monochloramine is also...

Autores: Miossec, Laurence.
The Water Framework Directive uses the “One-out, all-out” (OAOO) principle in assessing water bodies (i.e. the worst status of the elements used in the assessment determines the final status of the water body). Combination of multiple parameters within a biological quality element (BQEs) can be done in different ways. This study analysed several aggregation conditions within the BQE "Flora other than phytoplankton" (intertidal macroalgae, subtidal macroalgae, eelgrass beds and opportunistic blooms) using monitoring data collected along the Channel and Atlantic coastline.  Four aggregation criteria were tested on two sets of data collected between 2004 and 2014: OOAO, average, intermediate method between OOAO and average and a method taking into account an...

The REPAMO network (network ofmollusc pathology), created in 1986, ensures the survey of shellfish health status along French coasts according? to European Directives 91/67/EEC and 95/70/EEC. The aims of the network are 1 - to prevent the introduction and spread of exotic pathogens, 2-to study the means to decrease the impact of pathogens already present and to survey their evolution. In 2003, the REPAMO network focused on the survey oflisted diseases (bonamiosis and marteiliosis) in two areas under agreement process (Banc de Granville and zone X) and on the study of abnormal morlalities. Number of reported abnormal morlalities has increased in 2003. This rise can be partly explained by the recent network restructuring, but also by the summer heatwave and...

Emergence de maladies chez les organismes d'intérêt aquacole : quelques scénarios illustrés d'exemples
Provedor de dados: 5
Autores: Saulnier, Denis; Reynaud, Yann; Arzul, Isabelle; Miossec, Laurence; Le Roux, Frédérique; Goarant, Cyrille.
According to the world organisation for animal health (OIE) an emerging disease is defined as a recently admitted serious illness, whose aetiology can, or not, have already been established, and which is likely to be propagated within a population or between populations, for example at the time of international exchanges of aquatic animals and/or products of aquatic animals. Even though the emerging diseases that affect human health have been much studied, those which affect marine organisms and species of aquaculture interest in particular are poorly documented. By restricting emergence to only infectious diseases, we aim at presenting in a non-exhaustive way some scenarios of the emergence of the diseases of aquacultured species by illustrating them with...

Autores: Miossec, Laurence; Bocquene, Gilles; Truquet, Philippe.
Studying the impact of domestic sewer discharge on marine biota we studied lethal toxicity of tetrachloroethylene on brackish water prawn (Palaemonetes varians). These experiments were carried out in a flow-through system during 96 hours : LC 50 is 2,37 mg/l. This result and aIl data, present in litterature, show the high sensitiveness of crustaceans to this chlorinated solvent.

Viral gametocytic hypertrophy of Crassostrea gigas in France: from occasional records to disease emergence?
Provedor de dados: 5
Autores: Garcia, Celine; Robert, Maeva; Arzul, Isabelle; Chollet, Bruno; Joly, Jean-pierre; Miossec, Laurence; Comtet, Thierry; Berthe, Franck.
Viral gametocytic hypertrophy was reported for the first time in 2001 in Pacific oyster Crassostrea gigas in France. Since this date, the number of reported cases and the distribution area have increased every year; however, the cases are not associated with macroscopic signs or increased mortality rates. Both male and female gametes were hypertrophied and basophilic inclusions were observed in gamete nuclei, Transmission electron microscopy revealed the presence of viral particles in these intranuclear basophilic inclusions. These particles had characteristics similar to those of the Papillomaviridae and Polyomaviridae families: they were small, non-enveloped, icosahedral, and 44 to 56 nm in diameter, The viral particles were found in male, female and...

First results of an epidemiological study on oyster (Crassostrea gigas) mortality events in France during summer 2008
Provedor de dados: 5
Autores: Miossec, Laurence; Allain, Gwenhael; Arzul, Isabelle; Francois, Cyrille; Garcia, Celine; Cameron, Angus.
Abnormal mortalities occurred in most oyster producing areas in France during the summer of 2008.  The mortalities were sudden and severe (up to 100%) and mainly affected 6 to 18 month old juveniles.  Only Crassostrea gigas species was affected.  The cause of the mortality was unclear but OsHV-1 virus and bacteria belonging to Vibrionaceae family were frequently detected in affected populations. An epidemiological study was commenced in autumn 2008 in order to identify factors associated with, and the cause (or causes) of these mortalities.  This paper presents the results of the first (descriptive) part of this investigation.  The objectives were to identify the affected population and to describe the pattern of mortalities in time and space.  Mortality...

Autores: Miossec, Laurence; Garcia, Celine; Arzul, Isabelle; Francois, Cyrille; Joly, Jean-pierre; Chollet, Bruno; Robert, Maeva; De Blas, Isabelle.
The French network for the surveillance and monitoring of mollusc health (REPAMO) was officially set up in 1992 to control the shellfish status along the French coasts according to the European directives 91/67/EEC and 95/70/EC. The objectives are 1) the surveillance of notifiable diseases present in France (Bonamiosis and Marteiliosis of flat oysters Ostrea edulis), 2) the surveillance of health status of cultured and wild populations of molluscs, 3) the study of abnormal mortality and 4) the control of exchanges from European and third countries. In this context, a new surveillance programme, called Active Targeted Survey, part of the REPAMO, was applied in 2004 in order to improve the monitoring of the health status of the French mollusc populations...

Etude épidémiologique descriptive des mortalités exceptionnelles d'huîtres creuses enregistrées sur le littoral français en 2008
Provedor de dados: 5
Autores: Miossec, Laurence; Allain, Gwenhael; Arzul, Isabelle; Francois, Cyrille; Garcia, Celine; Cameron, Angus.
En 2008, des mortalités massives d'huîtres creuses (Crassostrea gigas) ont été recensées en France pendant l'été. Ce phénomène, observé de façon récurrente sur les côtés françaises depuis le milieu des années 70, a présenté un caractère exceptionnel en 2008 car il a été observé simultanément dans tous les bassins ostréicoles. De plus, les taux de mortalité calculés ont été particulièrement élevés (80 à 100 % pour de nombreux lots). La détection, fréquente et souvent simultanée, d'herpèsvirus OsHV1 et de plusieurs bactéries de la famille des Vibrionacées dans le cadre de la surveillance menée par le réseau national Repamo (réseau de pathologie des mollusques) a mis en évidence le caractère infectieux de l'épisode épidémique 2008. Une étude épidémiologique a...

A long term study of bonamiosis in Quiberon bay, France
Provedor de dados: 5
Autores: Arzul, Isabelle; Miossec, Laurence; Blanchet, Estelle; Garcia, Celine; Joly, Jean-pierre; Francois, Cyrille; Berthe, Franck.
Bonamiosis was first reported in association with mass mortality of flat oysters, Ostrea edulis, in June 1979 in L'Ile Tudy, Brittany. The disease rapidly spread to all of the oyster farming areas in France but also in other European countries. The French flat oyster production, which already suffered from another protozoan disease, marteiliosis, decreased from 5500 mt in 1979 to less than 2000 mt after 1980. In 2001, about 350 French farms sell 1650 mt of flat oysters. This production mainly relies on natural spat collection which specially occurs in Quiberon bay. One third of this spat is transferred from South to North Brittany for further growth. Quiberon bay constitutes an interesting site regarding the surveillance of bonamiosis because of the...

Nous disposons aujourd'hui d'o utils diagnostiques sensibles et spécifiques (PCR, HIS ... ) et d'un protocole de transmission de l' infection qui permettent d'assurer un suivi des productions larvaires en écloserie de bivalves pour les espèces considérées comme sensibles aux infections à herpèsvirus, mais également pour de nouvelles espèces. En effet, des mortalités massives (100 %) ont été rapportées dans une écloserie de coquille St-Jacques en Bretagne et ont pu être associées à la détection de OsHV -1. Les résultats obtenus concernant cette espèce, Pecten maximus, complètent et reflètent l'ensemble des travaux réalisés.
