Effect of virus pre-incubation in hypertonic salt solutions on viral replication in cells. (a) TAQMAN reverse transcription-polymerase chain reaction for the determination of A/H3N2 virus genome copies (gc) in the apical medium of MUCILAIR epithelia infected after incubation of the virus in salt solutions of various concentrations. Data are expressed as log10 A/H3N2 gc number/mL, quantified at 24 and 72 h post infection. Means ± standard errors are shown; n = 3. (b) Transepithelial electrical resistance (TEER) measurements in MUCILAIR epithelia 24, 72, and 144 h post infection. Means ± standard errors are shown; n = 3. The dotted line represents the 100 Ω·cm2 limit of tissue integrity. Mock, non-infected non-treated control culture; Triton X-100, detergent used as a positive control.
