Figure 4From: Effects of vaccinia virus uracil DNA glycosylase catalytic site and deoxyuridine triphosphatase deletion mutations individually and together on replication in active and quiescent cells and pathogenesis in miceLow multiplicity virus infection and spread in active and quiescent HFF. Confluent 6 well plates of active (A) and quiescent (B) HFF were infected with viruses at a multiplicity of 0.001. Every 24 h triplicate wells were harvested and titered on BS-C-1 cells. Average titers are shown. Error bars represent the standard error of the mean.Back to article page
