Field and mesocosm trials on passive sampling for the study of adsorption and desorption behaviour of lipophilic toxins with a focus on OA and DTX1
Provedor de dados: 5
Autores: Fux, E; Marcaillou-le Baut, Claire; Mondeguer, Florence; Bire, R; Hess, Philipp.
It has been demonstrated that polymeric resins can be used as receiving phase in passive samplers designed for the detection of lipophilic marine toxins at sea and was referred to as solid phase adsorption toxin tracking (SPATT). The present study describes the uptake and desorption behaviour of the lipophilic marine toxins okadaic acid (OA) and dinophysistoxin-1 (DTX1) from Prorocentrum lima cultures by five styrene-divinylbenzene based polymeric resins Sepabeads (R) SP850, Sepabeads (R) SP825L, Amberlite (R) XAD4, Dowex (R) Optipore (R) L-493 and Diaion (R) HP-20. All resins accumulated OA and DTX1 from the P. lima culture with differences in adsorption rate and equilibrium rate. Following statistical evaluation, HP-20, SP850 and SP825L demonstrated...

Etude d'un système de filtration de l'eau de mer pour l'alimentation des bassins conchylicoles insubmersibles durant des efflorescences toxiques. Rapport de fin de contrat : Cas d'une efflorescence à Alexandrium minutum et à Dinophysis spp
Provedor de dados: 5
Autores: Mondeguer, Florence; Marcaillou-le Baut, Claire.
Le littoral français est touché tous les ans par des proliférations d'algues toxiques dont l'ampleur géographique et la durée sont très variables selon les genres/espèces et les années. Par exemple, à partir du mois de mai, voire fin avril certaines années, les côtes sud de la Bretagne et celles des Pays de la Loire sont touchées par des proliférations de Dinophysis spp, genre responsable des intoxications diarrhéiques et cause la plus fréquente des fermetures de zones conchylicoles. Depuis 1988, la côte nord de la Bretagne est exposée à des efflorescences à Alexandrium minutum, producteur de toxines paralysantes. Ces fermetures répétées s'accompagnent d'une diminution, voire d'une cessation d'activité pour les établissements d'expédition car...

Etude de la décontamination de moules toxiques (toxines diarrhéiques) en laboratoire et en milieu naturel
Provedor de dados: 5
Autores: Marcaillou-le Baut, Claire; Bardin, B.; Bardouil, Michele; Bohec, Madeleine; Le Dean, Loic; Masselin, Pierre; Truquet, Philippe.
Two studies of depuration, one in laboratory conditions and the other one in an oyster's pond were performed using 2 sets of contaminated mussels with diarrhetic toxins at a high and a low level (3 and 1 M.U.). Depuration kinetics were followed both by the adult mouse test and okadaïc acid analysis. Results are - in the pond, high toxic mussels need about 20 days to become eatable (toxicity level : 0.5 M.U.g-1 digestive glands), -this time decreases when the initial toxicity is low but it increases when mussels are underfed, - a good correlation is observed between the total toxicity and okadaïc acid concentration.

Toxicité inexpliquée des moules de la baie de Lazaret (Toulon) entre novembre 1993 et mai 1994
Provedor de dados: 5
Autores: Amzil, Zouher; Marcaillou-le Baut, Claire; Bohec, Madeleine.
Depuis janvier 1993, des épisodes de forte toxicité des coquillages ont été observés lors des contrôles de routine en différents points des côtes françaises. Les souris ayant reçu des extraits de coquillages, par voie intrapéritonéale, présentaient des symptômes de type neurologique et mouraient au bout de 5 à 15 minutes. Cette toxicité n'a pu être attribuée à l'existence de phycotoxines connues. Les études préliminaires réalisées sur les glandes digestives de moules toxiques, récoltées lors d'un de ces épisodes (rade de Toulon), nous ont permis d'acquérir les données suivantes : le principe actif possède une forte polarité, il est thermostable, et il est stable dans le temps et en milieu acide. L'intoxication par voie orale chez la souris a permis de...

Contribution to toxicity assessment of Dinophysis acuminata (Dinophyceae)
Provedor de dados: 5
Autores: Marcaillou-le Baut, Claire; Mondeguer, Florence; Gentien, Patrick.
Blooms of Dinophysis in French coastal waters are implicated in most bans on marketing commercial bivalves. However, the relation between Dinophysis cell density and shellfish toxicity is not always consistent. Discrepancies may be due to the simple fact that it is nearly impossible to compare an integral over a few days (shellfish toxin content) and water samples. Furthermore, it seems that cells may have a variable specific toxicity. This work focuses on the variability in cell toxicity taking into account recent findings and using liquid chromatography coupled to mass spectrometry with an ion trap and electrospray interface. Esterified analogues of okadaic acid (DTX-4 and diol-esters) have been identified in cultures of Prorocentrum lima, another...

A bloom of the toxic dinoflagellate Alexandrium tamarense was observed for the first time in Thau iagoon between November and December 1998. Maximum cell concentrations detected in shellfish farming areas (85 000 Cells/1) were high enough to make mussels and clams unsuitable for human consumption (max. 850 ug. STX eq.100 g'1) while toxic levels in oysters did not exceed, or even reach, the international public health threshold established for PSP toxins.  This event, new to French Mediterranean waters, was investigated by both local and national veterinary services and by the Ifremer teams involved in the National Monitoring Network for Phytoplankton and Phycotoxines (Réphy). The chronological and operational description of the event was compared with data...

Development of sequence characterized amplified region markers from intersimple sequence repeat fingerprints for the molecular detection of toxic phytoplankton Alexandrium catenella (Dinophyceae) and pseudo-Nitzschia pseudodelicatissima (Bacillariophyceae) from French coastal waters
Provedor de dados: 5
Autores: Bornet, Benjamin; Antoine, Elisabeth; Francoise, Sylvaine; Marcaillou-le Baut, Claire.
Harmful algal blooms are a serious threat to shellfish farming and human health all over the world. The monitoring of harmful algae in coastal waters originally involved morphological identification through microscopic examinations, which was often difficult unless performed by specialists and even then often did not permit identification of toxic species. More recently, specific molecular markers have been used to identify specific phytoplankton species or strains. Here we report on the use of the intersimple sequence repeat (ISSR) technique to develop specific sequence characterized amplified region markers (SCAR) and to identify with these tools two toxic species in French coastal waters, the diatom Pseudo-nitzschia pseudodelicatissima (Hasle) Hasle and...

Provedor de dados: 5
Autores: Belin, Catherine; Marcaillou-le Baut, Claire; Amzil, Zouher; Ledoux, Martial.
This document describes and harmonizes detection methods of diarrheic (DSP) and paralytic (PSP) phycotoxins, for the laboratories of the Direction of Coastal Environment of IFREMER, which work in the framework of the French Phytoplankton and Phycotoxins Monitoring Network. These toxins, produced by a few phytoplankton species which regularly occur in sea water, accumulate in shellfish, which become toxic. Analysis is performed on an extract of digestive gland (DSP), or of total flesh (PSP), of shellfish. The described methods are meuse-tests, which are, at the present time, the only methods available to be used in the framework of a monitoring network. The method for diarrheic toxins is not standardized, with a threshold adapted for monitoring purposes. At...

Mise au point d'un test microcrustacé marin
Provedor de dados: 5
Autores: Marcaillou-le Baut, Claire; Le Dean, Loic; Chiffoleau, Jean-francois; Sanjuan, Jane.
Because of the low number of currently available toxicity tests for marine environment, the authors describe an experimental procedure using a marine copepod : Tigriopus brevicornis. This method can be used to quantify the 50 % inhibition of larval production or growth. The variability in controls larval production reaches about 9 %. The toxicity of two contaminants : tributyltin (TBTF) and cadmium chloride (CdCl2) was determined with this method and the 50 % decreases in larval production are respectively 1,4 µg/l (TBTF) and 61 µg/l (Cd++).

The toxins of marine microalgae
Provedor de dados: 5
Autores: Marcaillou-le Baut, Claire.
Exotoxins exert direct deleterious effects on flora and fauna: Some of them damage the cellular membrane, others have inhibiting effects on phytoplanktonic populations susceptible to coming into competition. In terms of pollution, exotoxins are especially a significant menace for aquaculture and although some are also bothersome for Man, we will not treat them here. Endotoxins accumulate in the food chain and reach humans via consumed sea products. They constitute a potential risk for human health and a scourge for the shellfish farming economy.

Etude de la dégradation et de la toxicité de la roténone en milieu marin
Provedor de dados: 5
Autores: Marcaillou-le Baut, Claire.
The use of rotenone as a means of predators eradication is necessary for the success of shrimps culture. Because these compound is a fish toxicant, some precautions have to be tacken in order to avoid the contamination of marine environment by the residual waters ; so the dissipation and the toxicity have been studied together in laboratory and in field assays. It appears that a delay of 15 days should be respected : this time is required for a total disappearing of the residual toxicity.

ISSR as new markers for genetic characterization and evaluation of relationships among phytoplankton
Provedor de dados: 5
Autores: Bornet, Benjamin; Antoine, Elisabeth; Bardouil, Michele; Marcaillou-le Baut, Claire.
In order to increase the molecular tools and markers needed for the identification of phytoplankton species, the inter simple sequence repeat ( ISSR) fingerprinting was adapted to micro-algae and its use in genetic analysis was demonstrated. Twelve strains, 6 Alexandrium, 4 Pseudo-nitzschia, 1 Skeletonema and 1 Tetraselmis were analysed for the first time with ISSR amplifications. The patterns were highly polymorphic and very reproducible. The 6 primers gave 223 polymorphic markers that clearly and easily distinguished all 12 strains ( mainly toxic ones) and gave 187 polymorphic markers among the Alexandrium and the Pseudo-nitzschia species. ISSR amplifications also indicated a large occurrence of simple sequence repeat ( SSR) in phytoplankton genomes,...

Les intoxications humaines résultant de la consommation de coquillages sont connues en France depuis plusieurs siècles. On peut supposer que la cause principale a d'abord été d'origine bactériologique, eu égard aux conditions de transport et à l'absence de contrôles de salubrité dans le passé. Quoi qu'il en soit, il faut compter aujourd'hui avec une autre origine, à savoir les proliférations de certaines algues unicellulaires planctoniques (phytoplancton), qui causent dans notre pays jusqu'à plusieurs milliers d'intoxications par an. Soulignons que la France a été jusqu'ici largement épargnée, puisque d'autres pays comptabilisent des dizaines ou centaines de décès depuis le début du siècle. On vient toutefois de découvrir la présence dans nos eaux côtières...

Azadinium spinosum (Elbrächter and Tillmann), a small marine dinoflagellate, has been recently described as a de novo producer of azaspiracid-1 and -2 (AZA1 and -2) diarrhoeic toxins. A culture of A. spinosum was established in our laboratory and optimised for pilot-scale production of this organism, to evaluate and understand AZA1 and -2 accumulation and biotransformation in blue mussels (Mytilus edulis) fed with A. spinosum.  Adult mussels were continuously exposed to A. spinosum over 1 week in 160 L cylindrical conical tanks. Three different diets were tested for contamination: 5000, 10 000 cells mL−1 of A. spinosum and a mixture of 5000 cells mL−1 of A. spinosum with 5000 cells mL−1 of Isochrysis aff. galbana (T-Iso, CCAP 927/14).

Autores: Le Gal, Dominique; Marcaillou-le Baut, Claire.
A cytodetection test of diarrhoeic phycotoxins was developped by both IFREMER and Nantes University. Its principle is based on cell morphological changes of KB strain, induced by inhibition of protein-phosphatases involved in cytoskeleton building. This test has been shown sensitive, fast and specific for protein phosphatase inhibitors like diarrhoeic toxins (specialy okadaic acid in France). It shows a high repeatability and reproducibility with pure toxin for the cell strain is highly stable (minimal active concentration or MAC = 125 ng OA.ml-1) In order to evaluate the efficiency oftransfering.the method to coastallaboratories, the assay was subjected to a prevalidation study.

La contamination des denrées d’origine marine par des toxines algales (phycotoxines) a pris depuis quelques années une importance considérable. Ce phénomène est largement lié à l’augmentation du nombre de zones géographiques touchées ainsi qu’à la diversification des espèces toxinogènes et à l’identification de nouveaux composés toxiques. Les données épidémiologiques sont cependant encore peu nombreuses car elles sont liées à la mise en place de contrôles systématiques récents. L’Union Européenne a établi un Laboratoire Communautaire de référence pour les phycotoxines, situé à Vigo (Espagne) qui coordonne les activités des laboratoires Nationaux de références correspondants (en France c’est le LNR Phycotoxines de l’AFSSA qui assure cette mission).

Autores: Marcaillou-le Baut, Claire.
The objective of the study was to pinpoint a possible effect of the food on the decontamination speed up of mussels containing DTX toxins. Studying the possible impact of food on the detoxification rate consists in i) following the toxin content over time for both feeding conditions and ii) checking the physiological state of the animals. For this purpose, an experimental protocol has been designed to describe the kinetics and to compare the detoxification rate in fed and non fed toxic mussels. The experimental disposal was available in an experimental oyster farm where the water and food supply qualities were controlled. The food supply consisted in a monospecific culture of the diatom Skeletonema costatum which is widely used in the shellfish...

Following exceptional outbreak of toxic dinoflagellate species in Vilaine Bay (summer 1983) a survey was carried out: variations in phytoplankton abundance and distribution in water and in mussel guts were followed. In the same time toxicity studies using mouse-test were performed with contaminated shellfishes, and mouse-test calibration was attempted. In spite of sampling and analysis conditions could be open to criticism, results obviously showed relation between shellfishes toxicity and occurrence of responsible species: Dinophysis acuminata.

As early as 1999, the EUROHAB initiative reported an urgent need for research on phycotoxin accumulation, detoxification and biotransformation rates in exploited shellfish species. It also strongly recommended a second objective of developing commercial systems for the cleansing of shellfish once contaminated with toxin. As a result, EU Framework Programs and regional programs funded a series of R &amp; D projects aiming to consolidate our understanding of contamination/detoxification pathways, together with the development of industrial scale detoxification processes and mechanisms. These studies attempted to accelerate the depuration process, for DSP in blue mussels, PSP in Pacific oysters and Manila clams, and ASP in King Scallops. Bulk culture...

The objective of this study was to identify a possible effect of food on the acceleration of decontamination in blue mussels, Mytilus edulis, containing diarrhetic toxins belonging to the okadaic acid (OA) structural group. An experimental protocol was designed to describe and compare the decontamination kinetics and detoxification rates of naturally OA-contaminated mussels that had either received or not received food for three weeks. The protocol was applied in two trials (in June 2006 and June 2007, called Ker06 and Ker07), conducted one year apart on samples of mussels collected in the same area, at the same season. Okadaic acid (OA), the main lipophilic toxin produced by the toxic alga Dinophysis acuminata, was analysed over the course of the...
