| 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... |

| 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,... |

| 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). |

| Developed for carrying out risk assessments under the European Commission (EC) Council Regulation No 708/2007 concerning the use of alien and locally absent species in aquaculture (ASR), the European Non-native Species in Aquaculture Risk Assessment Scheme (ENSARS) is briefly summarised, and the ‘Organism’ module is applied to the 24 species listed in ASR's Annex IV. Four other ENSARS modules (Infectious Agent, Facility, Pathway, and Socio-economic) were used to assess two case study species (European catfish Silurus glanis L. and red swamp crayfish Procambarus clarkii Girard). No Annex IV species was categorised as low risk, 10 as moderately low risk, 12 as medium risk, two as moderately high risk and none as high risk. The results are discussed and... |

| 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... |

| 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... |

| L'un des objectifs principaux des travaux en pathologie des mollusques est d'identifier et d'étudier des agents infectieux capables d'induire des maladies et des mortalités chez les coquillages, en particulier, chez I'huître creuse, Crassostrea gigas, espèce principalement exploitée en France. Ces travaux semblent d'autant plus indispensables qu'il n'existait pas, jusqu'à ces dernières années, de maladies identifiées chez I'huître creuse en Europe excepté le virus herpès suspecté dès 1995 de provoquer des mortalités de naissain (Renault et al, 1995). Les principales maladies des espèces proches sont dues à des parasites comme Haplosporidium nelsoni (Ford et Heskin, 1987) et Perkinsus marinus Olivier et al, 1 998) pour Crassostrea virginica, Marteilia... |

| A monitoring of the natural and high density populations of commercial molluscs is performed on an annual basis within the scope of the Repamo mollusc pathology monitoring network The aim of this surveillance is (1) to monitor the health status of the molluscs along the French coast and to produce a reference picture, and (2) to study the evolution of the noticeable pathogenic agents existing on the national territory. Different sampling strategies have been introduced for the past 15 years; each strategy is based on an active monitoring including the systematic study of natural mollusc deposits. Indeed, the natural and high density mollusc populations are interrelated and pathogenic agents can be and have been exchanged between these populations with... |

| 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.... |

| 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... |
