Figure 3

Representative sections from adult (A-C) and weanling (D-F) mice inoculated with diluent control (A, D) or RSV (B, C, E, F), each showing an airway (*) and blood vessel (bv). Perivascular and peribronchiolar inflammation were evident to a small degree at 5 d post RSV (B); and to a much greater extent at 7 d post RSV (C) in adult mice. Some parenchymal inflammation was also present at 7 d. Little to no evidence of inflammation existed in weanling mice at 5 d post infection (E); however a small degree of perivascular and peribronchiolar inflammation was present at 7 d post infection (F). Based on morphology these cells were classified as lymphocytes. Control mice did not show any evidence of inflammation at either age (A, D). Bar = 50 μm.
