Distribution of Tetrodotoxin in Pacific Oysters (Crassostrea gigas) [PDF]
Marine Drugs, 2021 A potent and heat-stable tetrodotoxin (TTX) has been found to accumulate in various marine bivalve species, including Pacific oysters (Crassostrea gigas), raising a food safety concern. While several studies on geographical occurrence of TTX have been conducted, there is a lack of knowledge about the distribution of the toxin within and between ...

Anesthesia in Pacific oyster,Crassostrea gigas [PDF]
Aquatic Living Resources, 2009 A reliable anaesthesia and sampling protocol for Pacific oysters will enable experiments to be conducted without sacrificing animals and will facilitate successive sampling of individuals for gametogenesis studies. As no such techniques were available for Crassostrea gigas, the present study aimed to define suitable anaesthetic conditions for use with ...

Introduction, establishment and expansion of the Pacific oyster Crassostrea gigas in the Oosterschelde (SW Netherlands) [PDF]
, 2009 The Pacific oyster Crassostrea gigas was first introduced as an exotic species by oyster farmers in 1964 in the Oosterschelde estuary (SW Netherlands). The initial phase is not well documented but first natural spatfall was recorded in 1975.

Perkinsus marinus in Crassostrea gigas in the Gulf of California [PDF]
Diseases of Aquatic Organisms, 2010 To determine the agent responsible for the massive mortalities of the Pacific oyster Crassostrea gigas in northwest Mexico, 30 oysters were sampled after a severe mortality event in 2006 along the Sonoran coast. Histological analyses revealed the presence of a protozoan and Ray's fluid thioglycollate medium (RFTM) assays showed the presence of ...

First isolation of Nocardia crassostreae from Pacific oyster Crassostrea gigas in Europe [PDF]
Diseases of Aquatic Organisms, 2008 In summer 2006 an extensive mortality of Pacific oysters Crassostrea gigas occurred in Lake Grevelingen, the Netherlands. A sample of Pacific oysters was investigated for the presence of shellfish pathogens as potential causes of the mortality. Yellow-green lesions were observed in several oysters upon clinical inspection.

Vibrio crassostreae sp. nov., isolated from the haemolymph of oysters (Crassostrea gigas) [PDF]
International Journal of Systematic and Evolutionary Microbiology, 2004 Polyphasic analysis of five new Vibrio isolates originating from the haemolymph of diseased cultured oysters is described. The new isolates were closely related to Vibrio splendidus, having 98 % 16S rRNA gene sequence similarity. gyrB phylogenetic analysis, fluorescent amplified-fragment length polymorphism (FAFLP) fingerprinting and DNA–DNA ...

Identification of the Molecular Clockwork of the Oyster Crassostrea gigas
PLOS ONE, 2017 Molecular clock system constitutes the origin of biological rhythms that allow organisms to anticipate cyclic environmental changes and adapt their behavior and physiology. Components of the molecular clock are largely conserved across a broad range of species but appreciable diversity in clock structure and function is also present especially in ...

Molecular diversity of antimicrobial effectors in the oyster Crassostrea gigas [PDF]
BMC Evolutionary Biology, 2010 Abstract Background To gain insight into the molecular diversity of antimicrobial peptides and proteins in the oyster Crassostrea gigas, we characterized and compared the sequence polymorphism of the antimicrobial peptides (AMPs), Cg-Defensins (Cg-Defs) and Cg-Proline Rich peptide (Cg-Prp), and of the bactericidal ...
