||Levels of infection and apoptosis in human respiratory epithelial cell lines were determined by immunostaining
techniques using anti-NP+IgG-FITC staining together with a TUNEL-based assay and DAPI staining.
||Human nasal and bronchial cells in vitro. Most (85 %) of the cells inoculated with virus
were infected at 12 h p.i. and this increased little with
time (maximum 95% 36–60 h p.i.).
