a Logarithm-transformed means and standard errors of OsHV-1 variant DNA concentration measured using qPCR over time from pooled spat (n = 3 pools, 5 spat per pool) in the plate assay for five random MBP families, two French selected resistant families, and one French selected susceptible family. No viral copies were detected at the start of the experiment (not shown due to log transformation). At day six, the OsHV-1 DNA concentrations (untransformed scale) of the French selected resistant families and the MBP families, which were not significantly different from each other (p > 0.05), were significantly less (p < 0.05) than the French selected susceptible family. At day seven, the MBP families had a significantly greater OsHV-1 DNA concentration than the French selected resistant families while the French selected susceptible family had an OsHV-1 DNA concentration that was not significantly different than either of the two other groups of families. No other within-day group comparisons were statistically significant in the untransformed scale. b Logarithm-transformed OsHV-1 DNA concentration distributions for live (n = 26) and dead (n = 22) random MBP oysters that were sampled on 1 August 2018 from Tomales Bay and tested positive for OsHV-1 by qPCR. Five live oysters tested negative for OsHV-1 (not shown due to log transformation) and one dead oyster has no amplifiable DNA. Logarithm-transformed means of live (OsHV-1 negative and positive) and dead oysters are shown by dashed vertical lines
