Primary OsHV-1 infection, bacterial dysbiosis, and secondary bacteremia are conserved in different infectious environments. a Early and intense replication of OsHV-1 µVar occurs in susceptible oysters (grey), but not resistant oysters (black), confronted with either the Atlantic or the Mediterranean infectious environment. OsHV-1 load was quantified by qPCR and expressed as Viral Genomic Units per ng of oyster DNA (log scale) during experimental infections. Asterisks indicate significant differences between susceptible and resistant oyster families (Mann Whitney test, p < 0.05). b, c Principal coordinate analysis (PCoA) plot of the microbiota for susceptible (grey) and resistant (black) oyster families confronted with each infectious environment. Dispersion of oyster families according to the Bray–Curtis dissimilarity matrix (beta diversity) in b Atlantic and c Mediterranean infectious environments. d Temporal dynamics of total bacteria in susceptible (grey) and resistant (black) oyster families confronted with two different infectious environments. Total bacterial quantification based on qPCR amplification of the V3-V4 region of the 16S rRNA gene during experimental infections. Asterisks indicate significant differences between susceptible and resistant oyster families (Mann Whitney test, p < 0.05). Data from the Atlantic infectious environment in panels (a) and (d) are extracted from [21] for comparison
