Groups (n=25) of 4–5-week-old wt and PKR−/− mice were infected ip with 5000 p.f.u. SFV A7(74). At various times post-infection, brain virus titres were determined by plaque assay. Each bar represents the mean (n=6) virus titre from wt (empty bars) or PKR−/− (filled bars) mouse brains. Error bars indicate sd. The limit of detection of the assay was 102.4 p.f.u. (g brain)−1. *P<0.05 (Mann–Whitney test).
