WebThe Pacific oyster Crassostrea gigas is a sessile bivalve mollusc whose homeostasis relies, at least partially, upon cells circulating in hemolymph and referred to as hemocytes. Oyster’s hemocytes have been reported to produce reactive oxygen species (ROS), even in absence of stimulation. Although ROS production in bivalve molluscs is mostly ... We developed a natural infection scheme to mimic disease progression in the environment by deploying SPF oysters (Supplementary Methods) and monitoring disease outbreak. As previous work has demonstrated that the disease occurs beyond a temperature threshold of ~16 °C (Petton et al., 2015a), we tested … See more On each sampling date, hemolymph was collected from eight ‘experimental’ living oysters (Supplementary Methods). The animals were then dissected to collect the gills, digestive gland … See more We first placed the isolates’ hsp60 sequences in a taxonomic framework using the software pplacer (Matsen et al., 2010). A reference phylogeny was constructed based on 60 Vibrionaceae type strains and … See more The 5, 1 and 0.22 μm filters were directly placed on Vibrio selective media (thiosulfate-citrate-bile salts-sucrose agar, TCBS) (Supplementary Methods).
