A European epidemiological survey of Vibrio splendidus clade shows unexplored diversity and massive exchange of virulence factors ArchiMer
Nasfi, H.; Travers, Marie-agnes; De Lorgeril, Julien; Habib, C.; Sannie, T.; Sorieul, L.; Gerard, J.; Avarre, J. C.; Haffner, Philippe; Tourbiez, Delphine; Renault, Tristan; Furones, D.; Roque, A.; Pruzzo, C.; Cheslett, D.; Gdoura, R.; Vallaeys, T..
The Vibrio splendidus clade has previously been associated with epidemic outbreaks of various aquatic animals, as in the case of the cupped oyster, Crassostrea gigas. To investigate whether involved strains could present a clonal origin and to identify possible alternative background carriage animals or zooplankton, a large epidemiological survey was conducted on isolates of the splendidus clade. For this purpose, Vibrio strains were isolated from various samples including oysters, mussels, sediments, zooplankton, and sea water on the basis of a North/South gradient of the European sea water zone (Ireland, The Netherlands, France, Italy, and Spain). A total of 435 isolates were successfully associated to the V. splendidus clade using real time polymerase...

A flow cytometric approach to study intracellular-free Ca2+ in Crassostrea gigas haemocytes ArchiMer
Aton, Emilie; Renault, Tristan; Gagnaire, Beatrice; Thomas Guyon, Hélène; Cognard, C; Imbert, N.
Bivalve haemocytes are essential in defence mechanisms including phagocytosis. They also produce molecules including hydrolytic enzymes and antimicrobial peptides that contribute to pathogen destruction. Although haemocyte activities have been extensively studied, relatively little is known about the intracellular signalling pathways that are evoked during haemocyte activation and especially the role of calcium. Flow cytometry has been used for the first time to define the effect of cell incubation in haemolymph and artificial sea water (ASW) on Pacific oyster, Crassostrea gigas, haemocytes. Cell viability, enzymatic activities (esterases and amino peptidases), phagocytosis and granulocyte percentage were analysed. Viability and some activities were...

A herpes-like virus infects a non-ostreid bivalve species: virus replication in Ruditapes philippinarum larvae ArchiMer
Renault, Tristan; Lipart, Cecile; Arzul, Isabelle.
Sporadic high mortalities were reported in June 1997 among hatchery-reared larval Manila clam Ruditapes philippinarum in a French commercial hatchery. Cellular abnormalities were observed in semi-thin sections in affected animals. Transmission electron microscopy revealed the presence of herpes-like virus particles in larvae. This is the first description of a herpes-like virus infection in larval R. philippinarum, a non-ostreid bivalve species. Virus particles were similar to other herpes-like viruses described from different oyster species with respect to ultrastructure and morphogenesis. Electron microscopic examination also demonstrated cells with condensed chromatin and extensive perinuclear fragmentation of chromatin. Like viruses infecting oysters,...

A study of autophagy in hemocytes of the Pacific oyster, Crassostrea gigas ArchiMer
Picot, Sandy; Morga, Benjamin; Faury, Nicole; Chollet, Bruno; Dégremont, Lionel; Travers, Marie-agnes; Renault, Tristan; Arzul, Isabelle.
Macroautophagy is a mechanism that is involved in various cellular processes, including cellular homeostasis and innate immunity. This pathway has been described in organisms ranging in complexity from yeasts to mammals, and recent results indicate that it occurs in the mantle of the Pacific oyster, Crassostrea gigas. However, the autophagy pathway has never been explored in the hemocytes of C. gigas, which are the main effectors of its immune system and thus play a key role in the defence of the Pacific oyster against pathogens. To investigate autophagy in oyster hemocytes, tools currently used to monitor this mechanism in mammals, including flow cytometry, fluorescent microscopy and transmission electron microscopy, were adapted and applied to the...

A unique self-organization of bacterial sub-communities creates iridescence in Cellulophaga lytica colony biofilms ArchiMer
Kientz, Betty; Luke, Stephen; Vukusic, Peter; Peteri, Renaud; Beaudry, Cyrille; Renault, Tristan; Simon, David; Mignot, Tam; Rosenfeld, Eric.
Iridescent color appearances are widespread in nature. They arise from the interaction of light with micron- and submicron-sized physical structures spatially arranged with periodic geometry and are usually associated with bright angle-dependent hues. Iridescence has been reported for many animals and marine organisms. However, iridescence has not been well studied in bacteria. Recently, we reported a brilliant “pointillistic” iridescence in colony biofilms of marine Flavobacteria that exhibit gliding motility. The mechanism of their iridescence is unknown. Here, using a multi-disciplinary approach, we show that the cause of iridescence is a unique periodicity of the cell population in the colony biofilm. Cells are arranged together to form hexagonal...

Adsorption of norovirus and ostreid herpesvirus type 1 to polymer membranes for the development of passive samplers ArchiMer
Hubert, Francoise; Morga, Benjamin; Renault, Tristan; Le Guyader, Soizick.
Aims This study was performed to develop passive sampling methodology for the detection of two viruses in seawater in the area of shellfish production, The Norovirus (NoV), a human pathogen implicated in gastroenteritis outbreaks linked to oyster consumption and the ostreid herpesvirus type 1 (OsHV-1) a virus associated with mass mortalities of Pacific oysters. Methods and Results Commercially membranes were tested for their capacity to adsorb virus: Zetapor, gauze, nylon, low density polyethylene (LDPE) and Polyvinylidene difluoride (PVDF). Laboratory exposures of membranes to contaminated water samples (stool, sewage, seawater) were performed. Our data shown that the amount of NoV GII genome per membrane measured with qRT-PCR increased with the time of...

Analysis of Clinical Ostreid Herpesvirus 1 (Malacoherpesviridae) Specimens by Sequencing Amplified Fragments from Three Virus Genome Areas ArchiMer
Renault, Tristan; Moreau, Pierrick; Faury, Nicole; Pepin, Jean-francois; Segarra, Amelie; Webb, Stephen.
Although there are a number of ostreid herpesvirus 1 (OsHV-1) variants, it is expected that the true diversity of this virus will be known only after the analysis of significantly more data. To this end, we analyzed 72 OsHV-1 "specimens" collected mainly in France over an 18-year period, from 1993 to 2010. Additional samples were also collected in Ireland, the United States, China, Japan, and New Zealand. Three virus genome regions (open reading frame 4 [ORF4], ORF35, -36, -37, and -38, and ORF42 and -43) were selected for PCR analysis and sequencing. Although ORF4 appeared to be the most polymorphic genome area, distinguishing several genogroups, ORF35, -36, -37, and -38 and ORF42 and -43 also showed variations useful in grouping subpopulations of this...

Analysis of hemocyte parameters in Pacific oysters, Crassostrea gigas, reared in the field — Comparison of hatchery diploids and diploids from natural beds ArchiMer
Gagnaire, Beatrice; Soletchnik, Patrick; Faury, Nicole; Kerdudou, Nolwenn; Le Moine, Olivier; Renault, Tristan.
Internal defence mechanisms of bivalves include the hemocytes which assume several functions. Relationships exist between environmental factors, physiological state of oysters, defence system and pathogens. Hatchery oysters are more and more produced and reared in the field. The characteristics and particularly the defence system of these animals are poorly documented. In this context, two field trials were carried out from May to September 2002 and from April to July 2003 in order to monitor hemocyte parameters of diploid oysters from natural beds and hatchery-produced diploid oysters using flow cytometry. Several hemocyte parameters (cell mortality, granulocyte percentage, phagocytosis, esterase and peroxidase activities) were monitored. For both oyster...

Antiviral immunity in the Pacific oyster, Crassostrea gigas: last development and perspective ArchiMer
Renault, Tristan; Faury, Nicole; Barbosa, Valerie; Moreau, Kevin; Haffner, Philippe; Pepin, Jean-francois.
Herpes-like viruses have been reported last decades in various marine mollusc species in association with mortality outbreaks throughout the world (Renault & Novoa 2004). One of these viruses isolated during French outbreaks has been characterised as an unassigned member of the Herpesviridae family and named ostreid herpes virus 1 (OsHV-1) or Pacific oyster herpes virus (Davison et al. 2005). Studying anti-viral non-specific defence mechanisms (innate immunity) is of great interest, because they constitute the only one in molluscs. Therefore, innate immunity has be investigated in the Pacific cupped oyster, Crassostrea gigas. The main aim of the work was focused on the identification and the characterisation of genes induced by OsHV-1 in the Pacific...

Appearance and spread of diseases among bivalve molluscs in the northern hemisphere in relation to international trade ArchiMer
Renault, Tristan.
Bivalve mollusc culture is a well-developed marine aquaculture activity in many countries around the world, notably in the northern hemisphere. During the development of this activity, numerous countries have been confronted with infectious diseases of varying severity and duration. Research has been conducted to determine the aetiology, epidemiology and control measures for these epizootics. Major epizootics in bivalve molluscs have been caused by viruses, bacteria, fungi and protozoan parasites. Moreover, important commercial relations exist in marine mollusc culture between different geographical areas. This must be taken into account in explaining the appearance and the spread of some infectious diseases in several countries around the world. The...

Autophagy in Pacific oyster, Crassostrea gigas ArchiMer
Moreau, Pierrick; Moreau, Kevin; Morga, Benjamin; Tourbiez, Delphine; Travers, Marie-agnes; Rubinsztein, David; Renault, Tristan.
Mass mortality outbreaks of Pacific oysters, Crassostrea gigas, are reported in different areas around the world affecting seriously the shellfish aquaculture sector. Two pathogens are associated with these mortality outbreaks, ostreid herpesvirus 1 (OsHV-1) and Vibrio aestuarianus. In this contexte, a better knowledge is needed in terms of oyster immunity. For this purpose, as an important degradation pathway autophagy was investigated in the Pacific oysters. An in silico research of genes involved in autophagy using the C. gigas genome allowed identification of homologs of ATG1 and ATG8/LC3(Microtubule-associated protein 1A/1B-light chain 3). Gene expression and protein detection were analysed using real-time PCR and western blot, respectively. ATG1 and...

Autophagy plays an important role in protecting Pacific oysters from OsHV-1 and Vibrio aestuarianus infections ArchiMer
Moreau, Pierrick; Moreau, Kevin; Segarra, Amelie; Tourbiez, Delphine; Travers, Marie-agnes; Rubinsztein, David C.; Renault, Tristan.
Recent mass mortality outbreaks around the world in Pacific oysters, Crassostrea gigas, have seriously affected the aquaculture economy. Although the causes for these mortality outbreaks appear complex, infectious agents are involved. Two pathogens are associated with mass mortality outbreaks, the virus ostreid herpesvirus 1 (OsHV-1) and the bacterium Vibrio aestuarianus. Here we describe the interactions between these 2 pathogens and autophagy, a conserved intracellular pathway playing a key role in innate immunity. We show for the first time that autophagy pathway is present and functional in Pacific oysters and plays an important role to protect animals from infections. This study contributes to better understand the innate immune system of Pacific...

Le réseau REPAMO (Réseau de Pathologie des Mollusques) est un réseau de santé animale, qui s'occupe des coquillages marins du littoral français métropolitain. Les mollusques marins des côtes françaises représentent une ressource par la pêche, mais sont surtout une part importante de l'aquaculture. Les pertes liées aux maladies dans ce domaine d'activité sont aujourd'hui considérées comme l'un des principaux facteurs limitants de son développement au niveau mondial. Deux exemples récents suffisent à illustrer ce danger pour l'ostréiculture française : • La culture de l''huître plate Ostrea edulis, déjà atteinte par un parasite, Marteilia refringens, est passée en quelques années de 20 000 tonnes à 1800 tonnes, suite à une épizootie. En effet à la fin des...
