From: Pathogeneses of respiratory infections with virulent and attenuated vaccinia viruses
Virus titers in the lungs (A) and the brains (B) of the infected mice. Groups of three to five mice were infected with 106 (â– ) and 104 (â–²) p.f.u. of WR and 106 p.f.u. (â–¡) of Wyeth intranasally for each time point, and their lungs and brains were analyzed at various time points post-infection. Titers were calculated as p.f.u./mg tissue for the lung and the brain. The error bars indicate the standard deviations. The data of titers in lungs at 18 days post-infection was under detection level (not plotted in graph A).
