Molluscan pathogens of concern to ASEAN ArchiMer
Bondad-reantaso, Melba; Berthe, Franck.
Pacific oysters were introduced into west coast of the USA from Matsushima Bay in Japan, infected with low levels of Haplosporidiumsp. identical to H.nelsoni(MSX) which causes high mortalities of Eastern oyster (C. virginica). A highly specific and sensitive DNA probe for H. nelsonican also detect Haplosporidium sp. in C.gigas of western US and Japan (Burreson and Stokes 2000).In 2002, H. nelsoni was detected in Japan using the same probe (Kamaishi and Yoshinaga 2002).Lesson: it appears that H. nelsoni does not cause serious disease in Pacific oysters; H. nelsoniis now speculated to have been introduced into the Pacific US by apparently healthy but infected C. gigas. Infected C. gigaswere introduced onto the east coast of the US where the parasite shifted...

Cultural practices and risk of shellfish pathogen exchanges : the oyster aquaculture in France ArchiMer
Miossec, Laurence; Girard, Sophie; Czerwinski, N..
The first national census concerning shellfish culture in France was carried out in 2002. The main purpose was to provide accurate and comprehensive information on the number and structure of the companies using an in depth review of production factors (leases, plants, equipment's, labour and qualifications), and a survey of cultural practices up to the market level. Moreover, the census aimed to quantify the bivalve sales dedicated to consumption and to measure the livestock transfers among rearing shellfish production areas at different developmental stages: spat, intermediate products and fully grown marketable products. The French oyster production reached 109 000 metric tons in 2001. The main production was observed in Poitou-Charentes region...

Antimicrobial effect of polyphenols from apple skins on human bacterial pathogens Electron. J. Biotechnol.
Alberto,María Rosa; Rinsdahl Canavosio,Matías Andrés; Manca de Nadra,María Cristina.
Apples possess many beneficial properties for the human health related with their high content in phenolic compounds. The antimicrobial effect of these compounds from the skin of two apple varieties, Royal Gala and Granny Smith, against human pathogens was examined. The phenolic compounds were extracted with the following solvents: A, acetone: water: acetic acid; B, ethyl acetate: methanol: water and C, ethanol: water. Total phenolic, flavonoid and non-flavonoid contents were analyzed in the extracts. The antimicrobial effect was determined using the agar diffusion method. The highest inhibitory effect of both apple varieties corresponded to extract A, which contained a high phenolic content. The Granny Smith extracts with higher phenolic content presented...

Modulations of the interactions between pacific cupped oyster Crassostrea gigas and Vibrio according to bacterial virulence and to genetic and physiological status of the host : Methodology and first results ArchiMer
De Decker, Sophie; Normand, Julien; Duperthuy, Marylise; Boudry, Pierre; Saulnier, Denis.
Rearing of Crassostrea gigas is the most economically important aquaculture activity in France. Bacteria belonging to Vibrio genus constitute one of the most abundant bacterial group in marine ecosystems. Two Vibrio species, V. splendidus and V. aestuarianus, were associated with many cases of mortality events in reared C. gigas spat and juvenile oysters, commonly during summer. This summer mortality syndrome has been extensively documented as the result of complex interactions between pathogens, host and environmental conditions. This work aims to study the Vibrio-host interactions and their modulations according to the virulence of pathogens and the genetic and/or physiological parameters of the host. These factors will be characterized by in vitro and...

The French Polynesian experience (Pearl oyster management, a manual) ArchiMer
Berthe, Franck; Prou, Jean.
French Polynesia is currently the world's largest producer of cultured black pearls with exports worth U5$150 millions annually. The activity has become of prime socioeconomic importance the archipelagos with strong support and control of the government. In the mid-1980s, mass mortality of the black-lipped pearl oyster, Pinctada margarltlfera, has occurred in several atolls and challenged the development of pearl farming activity. Consequent studies and surveys have described several pathological conditions. None of those is considered to pose significant threat to the industry. However, they are monitored by a surveillance program in order to prevent and control emerging diseases. The government of French Polynesia has developed efforts to maintain high...

Genomics and mollusc pathogens: trends and perspective ArchiMer
Renault, Tristan.
Global mollusc production is continuously increasing and reached 12.8 million tonnes in 2004 representing 28.2 percent of the total world production valued at US$ 9.4 billions. However, cultivated molluscs may suffer from severe mortality outbreaks. Among the possible causes is the occurrence of infectious diseases due to a variety of pathogens including protozoan parasites, bacteria and viruses. Preventing and controlling diseases has become a priority for aquaculture sustainability. However, molluscs are unique in terms of health management. Molluscs like other invertebrates, lack a true adaptative immune system. Vaccination can not be used to protect them against pathogens. Moreover, molluscs are usually reared in the open sea which strongly limits the...

Dynamique des populations de palourdes japonaises (Ruditapes philippinarum) dans le bassin d'Arcachon : conséquences sur la gestion des populations exploitées ArchiMer
Dang, Cecile.
The Manila clam Ruditapes philippinarum was introduced into Arcachon Bay at the beginning of the 1980s for aquaculture purposes. It rapidly naturalized in all intertidal flats of the lagoon. Nowadays, Arcachon Bay ranks at the first French place in terms of exploitable stock. However, recent stock assessments have shown an unbalance size structure with a deficit in juvenile and adult clams (> 38 mm shell length). These alarming patterns asked many questions on the sustainability of Manila clam populations within Arcachon Bay and have motivated the present thesis. This study aimed to better understand the population dynamics of this species and also some factors controlling this dynamic. The final objective was to improve the Manila clam fishing...

Abnormal mortality outbreaks occurred in the majority of Pacific oyster (Crassostrea gigas) producing areas in France in 2008 during the summer period. These outbreaks were usually sudden and severe (up to 100%) and affected essentially spat (oysters less than 1 year-old) and juveniles (12 to 18 month-old oysters). Crassostrea gigas was the single affected species Mortality outbreaks were first observed from mid May to mid June in Brittany, Vendée, Charente Maritime and Mediterranean coast A second episode of massive mortality events was reported at the end of June and the beginning of July. All oyster production sites were affected except some particular locations including Arcachon Bay and Brittany. Mortality occurred latter in Arcachon Bay in August....

[[abstract]]台灣菇蕈類絕大多數採用室內設施栽培,如太空包、塑膠瓶、堆肥床等栽培方式,僅極少數為段木栽培,其栽培介質需經堆積發酵及滅菌處理,無論接種、培養與出菇都須在可防止雜菌與病蟲害感染之環境下進行,但天然災害仍會對菇蕈產業造成不同程度的損害,當天災發生時,栽培使用的機械設備設施、栽培材料與生產環境都會受到污染,雜菌與病蟲害會隨著擴散而造成相當程度的危害,因此災後機械設備與栽培設施之清理、栽培材料與栽培基質處理、栽培環境之重整都顯得格外重要,天然災害發生是無可避免且甚難預防的,只要在災後迅速以正確的措施做好病害的預防管理,必能使栽培生產盡速復原。 Most mushrooms are cultivated in a closed growing room with basic or advanced facilities in Taiwan. The materials for mushroom cultivation are sawdust filled in polypropythlene bags or bottles, composts, and only few on logs. To avoid any possibilities of contamination from other microorganisms or insects, all substrates must be autoclaved, pasteurized, or composted before inoculation. After putting spawn into substrates, creating an almost sterile environment for spawn...
