This study was conducted to determine the presence of hepatitis A virus (HAV) in raw oysters (Crassostrea belcheri) using a virus concentration method and reverse transcription-nested polymerase chain reaction (RT-nested PCR). A total of 220 oyster samples were collected from oyster farms and local markets in Thailand. HAV was found in three oyster samples. Nested PCR products of HAV detected i...

The search for new markets in the seafood sector, associated with the question of the continuity of raw oyster consumption over generations can be an opportunity for processors to extend their ranges with oyster-based products. The twofold aim of this study was to evaluate the impact of processing and social representation on perception of oyster-based products by French consumers and to identi...

Scientific names: Crassostrea gigas (Thunberg 1793), Ostreidae, Bivalvia Synonyms: Gryphaea angulata Lamarck 1819; Ostrea gigas Thunberg 1793; Ostrea laperousii Schrenk 1861; Ostrea talienwhanensis Crosse 1862. Note: The Portuguese oyster Crassostrea angulata is a name often used for this species. According to genetic studies it was shown that Crassostrea angulata is likely a strain of Crassost...

both micronuclei (mn) and binuclei (bn) as well as rapd (random amplifying polymorphism of dna) assays are newly biomarkers which are well-introduced in toxic injury and related genotoxicity studies in bivalve, fishes and even humans. however, there is no record of such studies in iranian persian gulf coast line so far. for this propose, we analyzed frequency of mn and rapd patterns in gill cel...

UNLABELLED In the summer of 2010, Vibrio parahaemolyticus caused an outbreak in Maryland linked to the consumption of oysters. Strains isolated from both stool and oyster samples were indistinguishable by pulsed-field gel electrophoresis (PFGE). However, the oysters contained other potentially pathogenic V. parahaemolyticus strains exhibiting different PFGE patterns. In order to assess the iden...

The relative contributions of the spring-neap tides, river discharge and vertical behavior to the dispersal of eastern oyster (Crassostrea virginica) larvae in Delaware Bay is investigated with a coupled circulation-individual-based larvae model. The coupled model simulates larval growth and behavior along particle trajectories using temperature and salinity conditions obtained from an implemen...

In Korea, oyster culture began in the early 1900’s. Commercial oyster culture using the hanging system started in the 1960’s, on the southern coast. After the 1960’s, production of cultured oysters has increased every year to the late 1980’s with the highest production recorded at 288,078 metric tons in 1987. This upward trend stagnated in the 1990’s and production dropped to 174,117 metric ton...

Habitat suitability index (HSI) models provide spatially explicit information on the capacity of a given habitat to support a species of interest, and their prevalence has increased dramatically in recent years. Despite caution that the reliability of HSIs must be validated using independent, quantitative data, most HSIs intended to inform terrestrial and marine species management remain unvali...

The neuroendocrine-immune (NEI) regulatory network is a complex system, which plays an indispensable role in the immunity of the host. In the present study, the bioinformatical analysis of the transcriptomic data from oyster Crassostrea gigas and further biological validation revealed that oyster TNF (CgTNF-1 CGI_10018786) could activate the transcription factors NF-κB and HSF (heat shock trans...
