Fig. 2.
Recovery of RSV in bronchoalveolar lavage (BAL) fluid from RSV-infected baboons but not sham-infected baboons. The vertical axis represents the titer of RSV recovered in BAL fluids after inoculation of baboons with 8 × 107 plaque-forming units (pfu) of RSV or an equal volume of control preparation. The horizontal axis represents days after inoculation of baboons. The vertical arrow indicates the time of inoculation (immediately after time 0). RSV was recovered from all 10 baboons that were inoculated it with RSV and subsequently cultured but was not detected in BAL fluids from three sham-infected baboons. BAL fluids for culture were not available from baboons infected in. For RSV-infected baboons, n = 2–6 baboons at each time point, whereas n = 2–3 at each point for sham-infected baboons.
