Viral replication in mouse lungs. Six-week-old female C57BL/6 mice were infected intranasally with 105 PFU of each recombinant equine influenza virus and A/WSN/33 virus. Mice were sacrificed on days 2 and 4 postinfection, and viral titers in the lung were determined by immunofluorescence in MDCK cells. The graph represents the mean viral titer (± SEM) for each group.
