Autores: Гостюхина, О. Л.; Солдатов, А. А.; Головина, И. В.; Столбов, А. Я.
Исследовали состояние антиоксидантной системы (АОС) и содержание продуктов перекисного окисления липидов (ПОЛ) в гепатопанкреасе, жабрах и ноге черноморского моллюска Mytilus galloprovincialis Lam. Рассматривали 3 группы мидий, взятых одномоментно, – с черной, коричневой окраской раковины, а также с полосатой раковиной и депигментированными тканевыми структурами (белые мантийный край и нога, жабры и гепатопанкреас слабо окрашены). Депигментация тканей может встречаться у особей-альбиносов, а также в случае отсутствия или низкого содержания каротиноидов. Причина данного состояния на данном этапе не установлена.  Обнаружено, что депигментированные ткани отличались наибольшим содержанием перекисных продуктов. Наиболее заметные различия были выявлены в жабрах....

Анализ фенотипической структуры поселений мидий Mytilus galloprovincialis Чёрного моря по окраске  наружного призматического слоя раковины.
Provedor de dados: IBSS Repository
Autores: Шурова, Н. М.; Золотарёв, В. Н.
По особенностям распределения фиолетового пигмента в наружном призматическом слое раковин мидий Mytilus galloprovincialis Чёрного моря выделяется три фенотипа: (1) в призматическом слое фиолетовый пигмент отсутствует; (2) пигмент окрашивает весь призматический слой; (3) пигмент локализован в виде радиальных полос, чередующихся с непигментированными зонами. Первые две формы интерпретируются как гомозиготные, последняя – как гетерозиготная. Генетическая природа окраски раковины как системы двух аллелей с кодоминированием подтверждается соответствием выявленных и ожидаемых частот фенотипов по соотношению Харди-Вайнберга. На основе такого подхода рассмотрена фенотипическая структура ряда поселений мидий в северо-западной и западной частях Чёрного моря,...

Содержание α-токоферола во взвешенном веществе, тканях и биоотложениях Mytilus Galloprovincialis.
Provedor de dados: IBSS Repository
Autores: Поспелова, Н. В.
Проанализировано содержание витамина Е во взвешенном веществе, тканях и биоотложениях черноморской мидии Mytilus galloprovincialis. Показано, что содержание α-токоферола максимально в гепатопанкреасе моллюсков, в гонадах этот показатель зависит от стадии зрелости и возрастает от стадии гаметогенеза до стадии нереста. В сутки мидии потребляют 18% витамина Е от его абсолютного содержания в тканях, а выделяют только 6 – 10 % от потреблённого. Мидийное хозяйство «изымает» из среды до 387 г витамина Е.

Etude des variations saisonnières de différents biomarqueurs, chez la moule Mytilus galloprovincialis. Relation avec certains paramètres physiques, chimiques et physiologiques
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bodin, Nathalie.
The aim of this study was to evaluate the seasonal variations of six biomarkers on Mytilus galloprovincialis, using comparison with physiological index and chemical contamination levels on two sites of  Mediterranean sea. The seasonal variations of acetylcholinesterase (AChE), DNA adducts, benzo(a)pyrene hydroxylase (BPH), heat-shock proteins (HSP), metallothioneins (MT) and multixeniobiotic proteins (MXR) were estimated over a two-year period, on mussels which were sampled in Carteau (original site) and La Fourcade (transplanted organisms). Carteau, an industrial site, presents higher contamination levels (HAP, PCB, heavy metals) than La Fourcade, an urban area. The PAH profiles underline a strong spatio-temporal variability of levels and sources of...

Haemocytic neoplasia in Mediterranean mussels (Mytilus galloprovincialis) in the Slovene Adriatic Sea
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gombac, Mitja; Sitar, Rosvita; Pogacnik, Milan; Arzul, Isabelle; Jencic, Vlasta.
The health status of cultured and wild Mediterranean mussels in the Slovene Sea has so far been unexplored. Initially, 1280 adult Mediterranean mussels (Mytilus galloprovincialis), 960 from a shellfish farm and 320 from natural beds, were collected over a one-year period. Water temperature, oxygenation and salinity were measured at each sampling. Mussels were measured and weighted to calculate the condition index and microscopically examined for the presence of haemocytic neoplasia. Haemocytic neoplasia was detected in 14 mussels (1.1%) with a higher prevalence in cultured mussels. Neoplastic cells singularly infiltrated the connective tissue, in small foci or diffusely. Necrosis and multifocal atrophy of digestive tubules were noticed in mussels with...

Autores: Tsangaris, C.; Kormas, K.; Strogyloudi, E.; Hatzianestis, I.; Neofitou, C.; Andral, Bruno; Galgani, Francois.
A suite of biomarkers was measured in caged mussels at areas impacted by different anthropogenic activities along the Greek coastline to assess biological effects of environmental pollution. Mussels were caged at coastal sites in the vicinity of major cities, in areas influenced by major industries, agricultural practices and in islands away from known sources of pollution. Biomarkers indicative of neurotoxicity (acetylcholinesterase, AchE), oxidative stress (catalase, CAT), phase 11 biotransformation of xenobiotics (glutathione S-transferase, GST), metal exposure (metallothioneins, MTs) and protein synthesis (RNA:DNA ratio) were measured to assess effects of various types of pollutants. AchE activity proved to be the most responsive biomarker with...

The Mytilos project was carried during the last 3 years (2004-2006) in order to evaluate the level of chemical contamination along the coasts of the western basin of the Mediterranean Sea. Active mussel watch consisted of caged (12 weeks) Mytilus galloprovincialis at 123 stations along the Mediterranean coasts of Spain, France, Italy, North Tunisia, Algeria and Morocco. Results indicated total PAHs levels in the range 22-106 mu g/kg dry weight. All large towns or industrial areas from all countries of the basin were affected. Analysis of the origin of contamination demonstrated mainly a pyrolytic origin except in some areas such as Maddalena, Napoli, Alger, and Cornigliano (Genova). Statistical analysis of the PAHs accumulation data enabled the...

Modeling trace metal accumulation in the mediterranean mussel, mytilus galloprovincialis
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Casas, Stellio; Cossa, Daniel; Gonzalez, Jean-louis; Bacher, Cedric; Andral, Bruno.
Monitoring coastal contamination by trace metals pollution using mollusks bivalves as quantitative bioindicators is widely performed in many international biomonitoring programs. In this purpose, modeling metal dynamic in marine mussels is a reliable tool. It allows understanding the bioaccumulation process which results from the interactions between biological, chemical and environmental factors. To calibrate such a model, kinetic experiments on uptake and elimination were conducted on three Mediterranean sites chosen on the basis of their different nutritive and chemical characteristics.

Autores: Ndhlovu, Aldwin; Mcquaid, Christopher D.; Nicastro, Katy; Marquet, Nathalie; Gektidis, Marcos; Monaco, Cristian; Zardi, Gerardo.
By altering the phenotypic properties of their hosts, endolithic parasites can modulate the engineering processes of marine ecosystem engineers. Here, we assessed the biogeographical patterns of species assemblages, prevalence and impact of endolithic parasitism in two mussel species that act as important ecosystem engineers in the southern African intertidal habitat, Perna perna and Mytilus galloprovincialis. We conducted large-scale surveys across three biogeographic regions along the South African coast: the subtropical east coast, dominated by the indigenous mussel, P. perna, the warm temperate south coast, where this species coexists with the invasive Mediterranean mussel, M. galloprovincialis, and the cool temperate west coast dominated by M....

Influence of turbulence and turbidity on growth and survival of laboratory-reared bivalve larvae
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Seaman, Matthias; His, Edouard; Keskin, Mehmet; Reins, Torsten.
Laboratory-reared larvae of mussels (Mytilus galloprovincialis ) were incubated with and without sediment in a novel turbulence-producing machine. The sediments used were fine silt from the Gironde Estuary and from the German Wadden Sea. Larvae incubated in turbulence without sediment, and in suspended sediment concentrations similar to in situ conditions had growth rates which did not vary significantly from those of the controls. The growth rates of larvae incubated in 5 to 20 g/l of sediment were reduced by 20 to 50%. Survival was lower in larvae incubated with sediments than in turbulent and non-turbulent controls, but it was not correlated with sediment concentration. The results indicate that the mechanical effects of turbulence and turbidity on...

First record of Marteilia sp in mussels Mytilus galloprovincialis in Croatia
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Zrncic, Snjevana; Le Roux, Frédérique; Oraic, Drazen; Sostaric, Branko; Berthe, Franck.
Marteiliosis is a disease of molluscs caused by Marteilia refringens in Europe and M. sydneyi in Australia. During routine examination of cultured mussels Mytilus galloprovinciallis in the northern Adriatic, the occurrence of Marteilia sp. was recorded with a prevalence of 5 %. This parasite was not detected in flat oysters reared in the same area. The affiliation of the detected parasite in M. galloprovinciallis was confirmed by in situ hybridization using a M. refringens probe, specific at the genus level. DNA of these infected mussels originating from the same area will be used to clarify the taxonomic position of this species within the genus Marteilia using a molecular approach.

Bivalve predation by seabream has been observed worldwide and is a major concern for bivalve farmers. Farmed bivalve-seabream interactions must be better understood to ensure the sustainability of bivalve aquaculture. The objectives of this study were to characterize gilthead seabream Sparus aurata presence in a bivalve farm in Prevost Lagoon (Mediterranean Sea) using acoustic telemetry and to evaluate monthly losses of mussels Mytilus galloprovincialis and oysters Crassostrea gigas due to seabream predation over an 18 mo period inside the farm and at an unprotected experimental platform. Large (281 to 499 mm TL) seabream were more commonly detected in the bivalve farm than were small (200 to 280 mm TL) seabream. In contrast to small seabream, 90% of large...

Modélisation de la bioaccumulation de métaux traces (Hg, Cd, Pb, Cu et Zn) chez la moule, Mytilus galloprovincialis, en milieu méditerranéen
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Casas, Stellio.
Monitoring coastal contamination of trace metals using bivalve molluscs as quantitative bioindicators is widely used in many international monitoring programs. The bioaccumulation of metal within an organism results from the interaction between physiological (growth, loss of weight, absorption, accumulation), chemical (metal concentration, speciation, bioavailability) and environmental factors (temperature, SPM, chlorophyll). By utilizing the parameters above in this study, it appears that modeling metal dynamics in marine mussels is a reliable tool. The model allows understanding the bioaccumulation process which results from the interactions between biological, chemical and environmental factors. One of the objective of this study was to couple a...

Cytotoxic and antibacterial properties of Mytilus galloprovincialis, Ostrea edulis and Crassostrea gigas (bivalve molluscs) hemolymph
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Hubert, Florence; Van Der Knaap, Wil; Noel, Thierry; Roch, Philippe.
Mussel (Mytilus galloprovincialis) plasma contains cytotoxic activity against both vertebrate (erythrocytes and mouse tumour) and protozoan cells. Procaryotes (Escherichia coli and Vibrio alginolyticus) were not sensitive to the cytotoxicity. The activity was still present in dialyzed samples but was inhibited by heating at 45°C. Large individual variability which was not correlated with protein concentration and an increasing number of reactive specimens following injection, suggested that naive mussels were in various stages of immune response. Purification by anion exchange chromatography followed by gel filtration revealed a 320 kDa cytotoxic polymeric protein that acts through a polymerization process after binding onto target cell membranes as...

A comparison of growth and biochemical composition of Mytilus galloprovincialis (Lmk.) and Mytilus edulis (L.) on the West coast of Cotentin, Normandy, France 1999-2000
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Kopp, Joel; Cornette, Florence; Simonne, Charlotte.
The blue mussel, Mytilus edulis has been reared along the Normandy coast line since the 1960s. The gonadal cycle of this mussel species shows a sharp decrease in meat quality during the winter period after spawning. This decline in meat quality is so severe that sales have to be suspended from December to July. Another species of mussel, Mytilus galloprovincialis, which is reared in the lagoons along the French shore of the Mediterranean Sea has a different spawning cycle. An experiment was undertaken to study the meat quality of M. Galloprovincialis throughout the year after the spat were transferred from the Mediterranean Sea to the Normandy coast. This species showed an immediate adaptation to the gonadal cycle of M. edulis. Despite suggestions from...

Considering the filtration capacity of mussels to qualitative particle selection, our study focused directly on ingested species by assessing mussel stomach content of various size classes (1-5 cm) over a year (August 97-June 98) rather than monitoring seawater samples. Different size of mussels (1, 2, 3, 4, 5 cm in length) was sampled monthly from the sides of fish cage floats in Urla-Izmir. Stomach contents were analyzed under microscope and different plankton species were grouped taxonomically. Bacillariophycea, Dinophyceae, Oxyphceae, Euglenophyceae as phytoplanktonic species were observed in the stomach contents of mussels as well as zooplanktonic species including Ciliata, Cladocera, Copepod, bivalve and gastropod larvae. Over the sampling period,...

Can habitat specialisation maintain a mosaic hybrid zone in marine bivalves?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bierne, Nicolas; David, Pierre; Langlade, Aime; Bonhomme, F.
Maintaining the integrity of differentiated genomes in marine organisms needs efficient isolation mechanisms, because planktonic larval dispersion provides contacts between taxa. Habitat specialisation is interesting in this respect, because it can both prevent interspecific crosses (each taxon reproduces in its own habitat) and eliminate hybrids (typically less fit than a parental taxon in each habitat). The contact zone between smooth-shelled mussels Mytilus edulis and M. galloprovincialis in Europe is a good example, as allozyme genotypes typical of both taxa seem to segregate into different habitats. However, allozymes may be selected directly and it is not known whether the same pattern can be extended to the whole genome. Here, we used 6 presumably...

Steinhausia mytilovuln is a globally distributed microsporidian parasite which infects the oocytes of the blue mussels Mytilus edulis and M. galloprovincialis. Despite the intensive monitoring effort made on mussel populations, the parasite has not previously been reported in France. We report herein on the occurrence of S. mytilovum in Mytilus sp. from 1 cultured and 2 natural populations on the northern coast of France, thus extending the parasite's known distribution northwards. We also report on the observation in 1989 of S. mytilovum in M, galloprovincialis from the Golfe de Fos area in the Mediterranean Sea (South of France), S. mytilovum was observed in the European hybrid zone between M. edulis and M. galloprovincialis, which therefore renders the...

Autores: Croci, L; Demedici, D; Franco, E; Gabrielli, R; Dipasquale, S; Toti, L.
The depuration effectiveness of Poliovirus 1 and HAV contamined mussels, when subjected to flowing ozonized water, was evaluated. Mussels were experimentally contamined and then depurated up to 72 hours using a pilot depuration system with ozone treated and untreated water. The results showed that viral infectivity titter decreased more rapidly in mussels subjected to ozonized water (from 10 super(4) TCID50 to 10 super(1.5) TCID50 per ml of Poliovirus 1 but in the following period it remained unchanged. Also HAV was detected in the mussels after 72 h of depuration.

Delta de l'Ebre is a natural bay model for Marteilia spp. (Paramyxea) dynamics and life-cycle studies
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Carrasco, N; Arzul, Isabelle; Berthe, Franck; Fernandez Tejedor, M; Durfort, M; Furones, M.
Marteilia spp. are paramyxean parasites that affect several bivalve species of economic interest, such as Ostrea edulis and Mytilus galloprovincialis. Certain aspects of Marteilia spp., such as their life cycle and host affinity and infection dynamics, still remain unknown. The 'Delta de l'Ebre' constitutes a natural model for the study of the life cycle of the parasite Marteilia, since uninfected mussels and flat oysters immersed in the bays can become infected. This, along with the geographical and ecological characteristics of the bays, make it a very interesting location to study the Marteilia life cycle. Preliminary results concerning marteiliosis, mainly in mussels, such as prevalence dynamics, infectious periods, host affinity and host intermediate...

Observations sur le frai de Mytilus edulis Var. galloprovincialis (Lmk). Dates précises de frai. Facteurs provoquant l'émission de produits génitaux
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bouxin, H.
Durant sept années, de 1933 à la guerre, j'ai observé dans la région de Concarneau (Finistère) le frai de diverses espèces de Lamellibranches marins, notamment de la moule commune, Mytilus edulis var. galloprovincialis (Lmk). Les travaux sur le frai de la moule sont extrêmement nombreux. Les auteurs qui s'en sont occupés n'ont pas eu, en général, la possibilité d'observer les émissions elle-mêmes. Ils ont dû se contenter d'en induire l'époque soit d'après l'état des glandes génitales, soit en observant la présence de larves dans le plankton, soit, enfin, d'après la possibilité de fécondations artificielles. Or, si utiles que soient des observations de ce genre, elles ne permettent d'atteindre qu'à une probabilité de circonscrire qu'une époque relativement...

Bilan de l'état zoosanitaire des mollusques en Méditerranée française : 1988-2001
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Pichot, Yves.
The fact that molluscs from the Mediterranean have benefited from a privileged zoosanitary condition compared to those of the other French coasts has for a long time limited the control of farms and natural fields in this area. It is only in the early 70's, because of the pathological problems and risks observed in other areas that Mediterranean molluscs started to be stictly under zoosanitory control. This control was however limited until the early 90's. With the implementation of the European directives 91/67 and 95/70 for the protection of molluscs against diseases and their propagation, with the creation in 1992 of REPAMO- IFREMER (with a watch unit in the Mediterranean), the control of molluscs in the Mediterranean has considerably improved. Since...

New evidence for the involvement of Paracartia grani (Copepoda, Calanoida) in the life cycle of Marteilia refringens (Paramyxea)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Boyer, S.; Chollet, Bruno; Bonnet, D.; Arzul, Isabelle.
The dynamics of the protozoan parasite Marteilia refringens was studied in Thau lagoon, an important French shellfish site, for 1 year in three potential hosts: the Mediterranean mussel Mytilus galloprovincialis (Mytiliidae) the grooved carpet shell Ruditapes decussatus (Veneriidae) and the copepod Paracartia grani (Acartiidae). Parasite DNA was detected by PCR in R. decussatus. In situ hybridisation showed necrotic cells of M. refringens in the digestive epithelia of some R. decussatus suggesting the non-involvement of this species in the parasite life cycle. In contrast, the detection of M. refringens in mussels using PCR appeared bimodal with two peaks in spring and autumn. Histological observations of PCR-positive mussels revealed the presence of...

In situ kinetics of mercury bioaccumulation in mytilus galloprovincialis estimated by transplantation experiments
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Casas, Stellio; Cossa, Daniel; Gonzalez, Jean-louis; Bacher, Cedric; Andral, Bruno.
Monitoring coastal contamination by trace metals pollution using mollusks bivalves as quantitative bioindicators is widely performed in many international biomonitoring programs. For this purpose, studying mercury dynamic in marine mussels is a reliable tool. In situ experiments on uptake and elimination kinetics were conducted in three Mediterranean sites, chosen on the basis of their contamination levels. Mussels were transplanted from a clean area to a highly contaminated one and then transferred back to a clean site. This approach makes it possible to define bioaccumulation factors and uptake and elimination rates consistently with the real environmental conditions.

Autores: His, Edouard; Robert, Rene.
The collection of Crassostrea gigas veligeres in their natural environment and the homogenate technique (HIS et al., 1985) enable the monospecific culture of nine algae which larvae feed on. Four of them could be mass-produced: Nannochloris atomus, Stichococcus bacillaris, Chlamidomonas bullosa and Tetraselmis Tetrathele. Their feeding quality has been tested using the cross-growth method, and using Crassostrea gigas and Mytilus galloprovincialis veligeres. Although regularly found in the homogenates, and thus fed on by larvae, the first three algae gave poor results. Only Tetraselmis tetrathele has good nutritional qualities for Crassostrea gigas veligeres.

Assortative fertilization and selection at larval stage in the mussels Mytilus edulis and M-galloprovincialis
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bierne, Nicolas; David, Pierre; Boudry, Pierre; Bonhomme, F.
Assortative mating (prezygotic isolation) and reduced hybrid fitness (postzygotic isolation) are typically invoked to explain the stability of hybrid zones. In the tension zone model. these factors work in opposition to migration, which promotes genetic homogeneity. Many marine animals migrate over long distances through a planktonic larval stage. Therefore. strong reproductive isolation is needed to maintain stable marine hybrid zones. However, surprisingly little is known about mating preferences and hybrid fitness in marine organisms. Smooth-shelled mussels (Mytilus spp.) form a well-known species complex, with hybridization over extensive areas such as the contact zone of M. edulis and M. galloprovincialis around European Atlantic coasts.

Autores: Abadaboudjema, Ym; Dauvin, Jean-claude.
A long-term survey of two mussel populations from two natural mussel beds, Bordj El Kiffan and Boudouaou, was carried out from the end of 1984 to the beginning of 1991. Samples had been also collected from 1978-1979 then from 1992-1993, but only from the first of these. Maximal densities were higher than 10,000 ind. m(-2), due to the spring and summer heavy spatfall. At Bordj El Kiffan, densities of M. galloprovincialis were 50 times more important than those of P. perna. At Boudouaou, the abundance of P. perna was 1.7 times higher than that of M. galloprovincialis. From 1986 to 1988, the mean annual biomass in dry weight of tissue including ash was higher for P. perna at Boudouaou (0.886 kg. m(-2)) than at Bordj El Kiffan (0.486 kg. m(-2)). For M....

The French mussel industry : present status and perspectives
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Prou, Jean; Goulletquer, Philippe.
The French mussel industry produces around 60,000 metric tons on a yearly basis using two common species: Mytilus edulis, which is widely distributed along the Atlantic coastline, and Mytilus galloprovincialis, distributed mainly on Mediterranean shores. This production represents only half of the yearly consumption of mussels in France, leading to large imports from Spain and the Netherlands. Most imports occur between September and March, when the Atlantic production is reduced because of low meat quality due to spawning events. Although a public mussel fishery still exists, most production is based upon 3 culture techniques: on-bottom culture, longline and suspended culture, and bouchot-type culture, with the latter being developed in the l3lh century....

Autores: Benabdelmouna, Abdellah; Garcia, Celine; Ledu, Christophe; Lamy, Pierre; Maurouard, Elise; Degremont, Lionel.
In the context of mass mortality outbreaks affecting adult and juvenile mussels since 2014 in France, two investigations were conducted to study mussel mortality under laboratory conditions in 2015. The first investigated the horizontal transmission of a putative causal agent of the mortality among two stocks of wild Mytilus edulis and the potential genetic resistance of adults and their progenies. The second evaluated the resistance of pure and hybrid crosses of M. edulis and M. galloprovincialis at the spat stage to a mortality outbreak. For the first time in France, we described several mortality outbreaks affecting spat and adult mussels under laboratory conditions. Mortality was observed for seawater temperatures ranging from 10 to 23 °C, although the...

An integrated approach using biomarkers and contaminant levels in mussels Mytilus galloprovincialis L was employed to assess chemical contamination in Greek coastal waters within the framework of the MYTIMED program. Biomarkers (metallothioneins, glutathione S-transferase, catalase, acetylcholinesterase and RNA:DNA ratio) have been previously described in mussels caged at 14 sites in coastal areas influenced by different types of anthropogenic activities. This study applied a biomarker index, the Integrated Biomarker Response (IBR) to summarize biomarker responses and relate stress levels to concentrations of organochlorine compounds (PCBs, DDTs), polycyclic aromatic hydrocarbons (PAHs), and metals (Cu, Ni, Fe, Zn) measured in the mussel tissues. The IBR...

Multixenobiotic resistance protein expression in Mytilus edulis, M-galloprovincialis and Crassostrea gigas from the French coasts
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Minier, C; Moore, M; Galgani, Francois; Claisse, Didier.
Multixenobiotic resistance (MXR) is a membrane-transport mechanism that allows organisms to exclude many compounds from their cells and tissues. It is thus a first line of defence against a variety of toxic compounds. Since mussels and oysters possess MXR proteins, an analysis of the expression level of these membrane-transporters has been conducted in relation to their body burden of some major environmental contaminants. Mussels Mytilus edulis and M. galloprovincialis and the oyster Crassostrea gigas were sampled from a total of 43 sites along the French coasts. High expression levels were found in animals from the major French estuaries (Seine, Loire and Gironde), at a few sites in Brittany and in nearly all sites from the Mediterranean mainland coasts....

Autores: Delsert, Claude; Cancela Da Fonseca, Leonor.
The main objective of this project was to develop the tools for the in-depth understanding of mollusc biology and pathology. Such a goal has been reached in other biological systems through the development of molecular biology and cell culture. Indeed, development of a mollusc cell culture system is an essential step to approach many of the problems related to mollusc pathology, in particular to use molecular biology tools to study viral infection of these organisms. No continous cell line is available from bivalves and while cell cultures have been obtained from these organisms they are difficult to develop and labor intensive, survival cultures being maintained only for a few weeks. Our goal has been to study in detail many of the parameters involved in...

The Tributyl tin acetate, a component of certain antifouling paints, has deleterious effects on eggs and D shaped larvae from Crassostrea gigas at 5 p.p.b. (HIS &amp; ROBERT, 1980). Here we have tested concentrations as low as 1 p.p.b. on eggs and on 24 hours old larvae both from Crassostrea gigas and Mytilus galloprovincialis. The same results are got ; this product kills embryos and larvae in a few days ; it prevents growth of 24 hours old larvae exposed to this toxic. Mussels larvae seem to be less sensitive.

Abstract The genus Mytilus comprises a large number of bivalve mollusk species distributed throughout the world and many of these species are considered invasive. In South America, many introductions of species of this genus have already taken place, including reports of hybridization between them. Now, the occurrence of the Mediterranean mussel Mytilus galloprovincialis is reported for the first time from the Brazilian coast. Several specimens of this mytilid were found in a shellfish growing areas in Florianópolis and Palhoça, Santa Catarina State, Brazil. Morphological analysis of the shells and molecular analysis through sequencing of the cytochrome oxidase subunit 1 (COI) confirmed the taxonomic identification. The species is known for its great...

Modification of pyruvate kinase and lactate dehydrogenase in foot muscle of the sea mussel Mytilus galloprovincialis under anaerobiosis and recovery
Provedor de dados: Brazilian Journal of Medical and Biological Research
The modification of pyruvate kinase (PK) and lactate dehydrogenase (LDH) activity in foot muscle of the mussel Mytilus galloprovincialis during exposure to air and recovery in water was investigated. In the course of exposure to air, the activity of these enzymes measured at high and low substrate concentrations showed successive increases and decreases. Returning the mussels to water after exposure to air affected enzyme activity in a manner similar to anaerobiosis. When measuring at saturated concentrations of substrates and substrate and coenzyme for PK and LDH, respectively, the maximum activation of PK (37%) was observed at 4 h of animal exposure to air, and for LDH (67%) at 6 h exposure to air. During 24 h of exposure of animals to air, PK activity...
