FIG 1.

HRV RNA loads measured by real-time RT-PCR at the apical surface of three-dimensional human airway epithelium reconstituted in vitro and inoculated with HRV-A16, the patient's nasopharyngeal aspirate, or the patient's serum or not infected (3). Absolute copy numbers present in the input (100 μl) or apical washes (200 μl) collected at different time points are indicated. Error bars show standard deviations calculated from two independent biological replicates. *, RNA load measured 4 h postinoculation represents the leftover inoculum. NPA, nasopharyngeal aspirate.
