Monoclonal antibodies against sporangia and spores of Marteilia sp. (Protozoa: Ascetospora)
Provedor de dados: 5
Autores: Robledo, Jaf; Boulo, Viviane; Mialhe, Eric; Despres, Béatrice; Figueras, Antonio.
Digestive glands of mussels Mytilus edulis from Brittany, France, infected with Marteilia sp. (Ascetospora) were used to purify the parasite. A modification of a previously used purification protocol increased purification efficiency, permitting sporangial primordia and sporangia of Marteilia sp. to be obtained. Mouse (Balb/c) monoclonal antibodies were generated against this parasite. From the fusion, 26 monoclonal antibodies against Marteilia sp. were obtained. Antibodies from 6 clones reacted only with Marteilia sp. cells and not with normal host tissues. Four of these antibodies (1/1-3, 3/1-1, 4/1-1 and 6/2-3) reacted with the sporangia wall and two with the spore cytoplasm (9/1-1 and 12/5-1). Antibodies cross-reacted with Marteilia refringens from...

Chemiluminescence analysis of the activity of Pecten maximus hemocytes stimulated with zymosan and host-specific Rickettsiales-like organisms
Provedor de dados: 5
Autores: Le Gall, G; Bachere, Evelyne; Mialhe, Eric.
During a study of Rickettsiales-like organisms (RLO) in Pecten maximus gill, histological observation of free RLO in hemoclymph led us to consider interactions between the pathogen and the hemocytes. Firstly, the production of oxygen radicals by hemocytes was established using a luminol-enhanced chemiluminescence method with zymosan axs stimulant. The effects of serveral inhibitors of oxidative metabolism were investigated. The internalization of RLO into hemocytes was demonstrated by electron microscopy but was not related to chemiluminescent activity. The possible involvement of RLO acid phosphatase as the inhibitor of respiratory burst was assessed.

In vitro culture of mollusc hemocytes. Functional study of burst respiratory activity and analysis of interactions with protozoan and procaryotic pathogens
Provedor de dados: 5
Autores: Boulo, Viviane; Hervio, Dominique; Morvan, Annie; Bachere, Evelyne; Mialhe, Eric.
The chief importance of hemocytes as immune effectors in molluscs has led to develop researches for in vitro culture. The chemiluminescence technique has been used to estimate the phagocytosis capacity of Crassostrea gigas hemocytes according to different culture media and times. Sea water was used as a basic medium. Additives, such as antibiotics or glucose and buffers, such as Tris or Hepes, were tested as weIl as artificial sea water. Hemocyte chemiluminescence activities were recorded at t=o in relation to the medium composition. The highest values were observed when hemocytes were kept in sea water without any modification. Whichever medium, chemiluminescence activity was substantially decreased when hemocytes were previously kept in vitro for a few...

An infection of Ruditapes decussatus (Bivalvia) by Rickettsia
Provedor de dados: 5
Autores: Mialhe, Eric; Chagot, Dominique; Boulo, Viviane; Comps, Michel; Ruano, Francisco; Grizel, Henri.
The authors report the presence of a Rickettsia in Ruditapes decussatus from natural populations of the Algarve (Portugal). Light microscopic shows infections of varying importance in gill tissues. Some enclose small procaryotic colonies (cp) scattered in all lamellae; in others, the colonies are scarce and hypertrophic (100 mu m). These different pictures suggest an amplification process. Digestive diverticulae may also be infected, but to a lesser extent. The ultrastructural features of this intravacuolar (mvd: densified vacuolar membrane) procaryote (P) and its multiplication by scission without a complex developmental cycle allows its classification in the order Rickettsiales.

Persistence of infectious pancreatic necrosis virus (IPNV) in scallops Pecten maximus
Provedor de dados: 5
Autores: Mortensen, Stein Hàkon; Bachere, Evelyne; Le Gall, Ghislaine; Mialhe, Eric.
Infectious pancreatic necrosis virus (IPNV), serotype N1 isolated from scallops Pecten maxjmus in Norway, was propagated and used in both inoculation and bath challenge experiments with scallops in vivo. Although virus titers measured in scallop tissues decreased, depuration of virus was not complete during the experimental periods. TPNV was still detectable 11 mo after injection. The highest virus titer was found in the hepatopancreas, but virus was also detectable in other tissues, as well as in the hemolymph. After a bath challenge, uptake of IPNV was shown. Virus was present in hepatopancreas, gonad, kidney, mantle, gill, rectum and in the hemolymph 1 d after the uptake. The titer was highest in the hepatopancreas where virus was detectable at the end...

Genomic DNA cloning of rickettsia-like organisms (RLO) of Saint-Jacques scallop Pecten maximus : evaluation of prokaryote diagnosis by hybridization with a non-isotopically labelled probe and by polymerase chain reaction
Provedor de dados: 5
Autores: Kellner-cousin, Kristell; Le Gall, G; Despres, Béatrice; Kaghad, M; Legoux, P; Shire, D; Mialhe, Eric.
Genomic DNA fragments of a rickettsia-like organism (RLO) of Saint-Jacques scallop, Pecten maximus, were extracted from purified RLO and cloned. A DNA sequence of 1500 bp taken from one of the sequenced clones was coupled to horseradish peroxidase and the resulting probe was assayed for the diagnosis of RLO by nucleic acid hybridization. The specificity of the probe for RLO DNA was established from its lack of hybridization with scallop DNA. The sensitivity limit of the probe detected by enhanced chemiluminescence was determined to be around 500 ng of total RLO nucleic acids, equivalent to about 2.5 X 106 copies of RLO DNA. A pair of polymerase chain reaction (PCR) primers were synthesized that amplified a 1300 bp segment of the 1500 bp RLO fragment. After...

Recherches actuelles en pathologie des mollusques
Provedor de dados: 5
Autores: Mialhe, Eric.
The different epizooties affecting traditional or recent shellfish culture activities (hatcheries, cockle culture) brought to light some microorganisms and parasites considered as the responsible pathogenic agents. However, in a number of cases, the etiology of these massive mortalities remains unexplained (Grassostrea gigas, Ruditapes philippinarum). Some additional works, based on some electron microscopy techniques and isolation methods, are thus essential in order to precise the infectious nature of these diseases.

Epizootiological study of rickettsiosis of the Saint-Jacques scallop Pecten maximus
Provedor de dados: 5
Autores: Le Gall, G; Mialhe, Eric; Chagot, D; Grizel, Henri.
Rickettsia-like microorganisms were described in gill endothelial cells during mass mortalities of Saint-Jacques scallops Pecten maximus in Saint-Brieuc Bay (North Brittany, France) during winter 1985-86. In order to evaluate the epizootiological significance of rickettsiosis of scallops, an analytical and descriptive epizootiological study was undertaken. The study included the geographic distribution, incidence and severity of the disease for several northern European and French scallop populations. Since the center of French scallop production is in Saint-Brieuc Bay, epizootiological investigations were concentrated in this area. Dissemination appeared to be by horizontal transmission. The pathogenic significance of the rickettsia-like organism in...

Strategy of researches on marine bivalve defense mechanisms
Provedor de dados: 5
Autores: Bachere, Evelyne; Mialhe, Eric; Noel, Thierry; Boulo, Viviane; Hervio, Dominique; Le Gall, Ghyslaine; Morvan, Annie.
Because of the impact of infectious diseases in marine mollusc aquaculture, research has been initially developed in pathology in term of epidemiology and diagnosis. The establishment of basic techniques for in vitro and in vivo studies of host/pathogen interactions and the progresses in the field of cellular and molecular biology have permitted to undertake researches in immunology. Parallel to fundamental interest in understanding defense mecanisms of molluscs against pathogens, applications may be expected for resistant strains obtained by genetic engineering.

Localisation and characterization of acid phosphate activity in Bonamia ostreae (Ascetospora), an intrahemocytic protozoan parasite of the flat oyster Ostrea edulis (Bivalvia)
Provedor de dados: 5
Autores: Hervio, Dominique; Chagot, Dominique; Godin, Pierre; Grizel, Henri; Mialhe, Eric.
Acid phosphatase activity was cytochemically detected at the ultrastructural level in the protozoan Bonamia ostreae, an intrahemocytic parasite of the flat oyster Ostrea edulis. Lead nitrate was used as capture agent for phosphate liberated during the hydrolysis of the subtrate (cytidine 5' monophosphate). Lead phosphate precipiation, indicative of enzyme activity, was located in membrane-bound organelles corresponding to the cytoplasmic inclusions known as "dense bodies". Acid phosphatase activity level and sodium L-tartrate inhibition were measured spectrophotometrically from a purified parasite suspension. The possible involvement of this enzyme in intracellular survival of B. ostrea is discussed.
