A long term study of bonamiosis in Quiberon bay, France ArchiMer
Arzul, Isabelle; Miossec, Laurence; Blanchet, Estelle; Garcia, Celine; Joly, Jean-pierre; Francois, Cyrille; Berthe, Franck.
Bonamiosis was first reported in association with mass mortality of flat oysters, Ostrea edulis, in June 1979 in L'Ile Tudy, Brittany. The disease rapidly spread to all of the oyster farming areas in France but also in other European countries. The French flat oyster production, which already suffered from another protozoan disease, marteiliosis, decreased from 5500 mt in 1979 to less than 2000 mt after 1980. In 2001, about 350 French farms sell 1650 mt of flat oysters. This production mainly relies on natural spat collection which specially occurs in Quiberon bay. One third of this spat is transferred from South to North Brittany for further growth. Quiberon bay constitutes an interesting site regarding the surveillance of bonamiosis because of the...

A preliminary study of the aetiology, epizootiology and pathology of 'rusty-yellow' skin discolouration of tilapia species (Oreochromis niloticus and Tilapia zilli OceanDocs
Oladosu, H.A.; Ayinla, O.A.; Ajiboye, M.O.; Egbomuche, G.; Onuoha, G.C..
An upsurge in the prevalence of rusty-yellow discoloration of the skin of the two tilapia species, being cultured at the African Regional Aquaculture Centre (ARAC), gave a basis for an urgent clinical and epizootiological studies of the condition. The studies were therefore carried out along with the performance of some catfishes in polyculture with Oreochromis niloticus, under the integrated poultry cum fish farming system. It was observed that this condition affects the tilapia species only, and the antemortem, and postmortem examination revealed that the discolouration is restricted to the surface of the cutaneous tissue; affecting the underside of the exposed part of the scales, the fins and the skin flap covering the scale pockets, mostly in adult...

An infection of Ruditapes decussatus (Bivalvia) by Rickettsia ArchiMer
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.

Analyse bibliographique: historique de l'huître plate, Ostrea edulis, et la Bonamiose, maladie due au protozoaire Bonamia ostreae ArchiMer
Cochennec-laureau, Nathalie.
Oyster productions represent an important part of the french aquaculture. However, diseases are considered as the first limiting factors for the development of this activity around the world. Two exemples point out this problem for the french flat oyster production: Marteiliosis, the disease of the digestive gland, caused by Marteilia refringens, and Bonamiosis, the hemocytic disease, caused by Bonamia ostreae. This report proposes a bibliography analysis of major results obtained for Bonamiosis studies.

PINTO, N.F.J. de A..
Sementes de milho (Zea mays L.) da cultivar HS 200 foram tratadas com os seguintes fungicidas e doses (g i.a./100 kg sementes): tolylfluanid (50,0), tolylfluanid (75,0), tolylfluanid + carbendazim (50,0 + 20,0), tolylfluanid + carbendazim (50,0 + 30,0), captan (120,0). Sementes sem tratamento fungicida constituiram a testemunha. Quanto a fungitoxicidade, a mistura tolylfluanid + carbendazim destacou-se no controle de Fusarium moniliforme Sheld., Aspergillus spp. e Penicillium spp. associados as sementes de milho. Em relacao as emergencias de plantulas em solo esterilizado e em semeadura em campo, nao ocorreu diferenca significativa entre os tratamentos. Entretanto, no teste de frio em solo com monocultivo de milho, os fungicidas captan e tolylfluanid...

Bacteries associees aux production de Brachionus plicatilis ArchiMer
Nicolas, Jean-louis; Joubert, M.
Bacteria associated with semi-continuous culture of Brachionus plicatilis , which is used as the first food of marine fish larvae, were counted on Zobell 2216 E medium and identified. The numbers of bacteria were very high in both Brachionus (about 10 super(11) bact. per ml of digestive content) and in water (from 1.6.10 super(6) to 4.7.10 super(7) bact. per ml). The cultures were studied at driving a time when mortalities occurred frequently. The introduction of a Pseudomonas) phenon at a proportion of about 50% to the dominant microflora persisted in time and was little influenced by diet. It has been the cause of the repression of the Vibrio, Aeromonas group which was found in an unusually small proportion. It induced a lack of microflora diversity and...

The REPAMO network (network ofmollusc pathology), created in 1986, ensures the survey of shellfish health status along French coasts according? to European Directives 91/67/EEC and 95/70/EEC. The aims of the network are 1 - to prevent the introduction and spread of exotic pathogens, 2-to study the means to decrease the impact of pathogens already present and to survey their evolution. In 2003, the REPAMO network focused on the survey oflisted diseases (bonamiosis and marteiliosis) in two areas under agreement process (Banc de Granville and zone X) and on the study of abnormal morlalities. Number of reported abnormal morlalities has increased in 2003. This rise can be partly explained by the recent network restructuring, but also by the summer heatwave and...

Bonamia ostreae and Ostrea edulis : a stable host-parasite system in France? ArchiMer
Arzul, Isabelle; Miossec, Laurence; Blanchet, Estelle; Garcia, Celine; Francois, Cyrille; Joly, Jean-pierre.
Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting flat oysters Ostrea edulis. After its first description in June 1979 in L'Ile Tudy, Brittany, the parasite rapidly spread to all French oyster farming areas and in other European countries through transfers of live molluscs. Bonamiosis and marteiliosis, another protozoan disease appeared in the seventies, drastically reduced the French flat oyster production from 20 000 tonnes in 1970 to less than 2000 tonnes after 1981. In 2001, about 1650 t of flat oysters were marketed in France. The production is restricted to several areas specialised in reproduction, growth and/or marketing, and depends on transfers of animals. Most important production...

Brown muscle disease (BMD), an emergent pathology affecting Manila clam Ruditapes philippinarum in Arcachon Bay (SW France) ArchiMer
Dang, C; De Montaudouin, X; Gonzalez, P; Mesmer Duldons, N; Caill-milly, Nathalie.
We describe an emerging pathology, brown muscle disease (BMD), which specifically affects the Manila clam Ruditapes philippinarum in Arcachon Bay (France). BMD induces a transformation of the posterior adductor muscle, which becomes infused by conchiolin and calcified, reducing the ability of clams to bury. The disease affects both types of muscular tissue, with striated muscle becoming affected to a higher degree than smooth muscle. Two indices were created to quantify the symptoms: the Muscle Print Index, used for empty and live shells, and the Final Disease Index, utilized for live clams only. Histological sections were made and observed under light microscopy to examine the muscular damage and to investigate a causal agent. Sections revealed an...
