Última REPHY (Réseau de Surveillance du Phytoplancton et des Phycotoxines). Méthodes de détection des phycotoxines diarrhéïques (DSP) et paralysantes (PSP). Méthodes biologiques sur souris ArchiMer 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...

The oyster Crassostrea gigas is one of the most commercialized molluscs in the world. It is a very cosmopolitan species that has been disseminated by humans and is susceptible to various agents such as pathogens (bacteria, viruses), parasites, xenobiotics and/or toxic micro-algae. As a filter-feeder, it may accumulate phyco- toxins while feeding on harmful algal blooms (HAB), including paralytic shellfish toxins (PST). To protect human health shellfisheries harvesting are closed dur- ing HAB, impacting the aquaculture industry. This PhD work aims to develop a Dynamic Energy Budget (DEB) based model to describe kinetics of PST accumulation and detoxification in C. gigas. Interest of coupling bio-accumulation to DEB model lies in the inclusion of...

Ano: 2017 URL: http://archimer.ifremer.fr/doc/00456/56792/58631.pdf Modélisation de la détoxication de mollusques bivalves contenant des phycotoxines paralysantes ou diarrhéiques ArchiMer Gueguen, Marielle. The purpose of this study is to implement models to describe detoxification kinetics of Pacific oysters Crassostrea gigas and Blue mussels Mytilus edulis containing paralytic and diarrheic phycotoxins respectively. First, experimental trials made it possible to complement data from the literature regarding the understanding of processes involved in mollusc detoxification. In particular, they pointed out a difference in the mollusc capacity to degrade cellwalls of phycotoxin-producing dinoflagellates, according to their en cystement capacities. It was observed that paralytic phycotoxins reached the various oyster tissues whereas diarrheic toxins were mainly sequestred in the digestive gland of mussels. The latter seem to be retained by lysosomes localized...
