Figure 1.

Percentage of infected spat according to the viral load in log class. The level of virus is expressed in genomic units (GU) per nanogram of DNA and illustrate viral load at (A) the field oyster growout site and in the (B) sanctuary site (dark grey - CRIC) and in the tank (grey – CAB)) during mortality events observed in the field. The asterisks indicate the sample taken for microarray analysis. For graphic A, the first asterik corresponds to sample infected at 4 viral GU ng^-1 of DNA (BL), and the second refers to samples infected at 14 viralGU ng^-1 of f DNA ( i). Data in B are from spat considered to be uninfected.
