Virus titer detected in the supernatant of influenza virus infected ud- and wd-NHBE cells.

Abstract

<p>Virus titer of the (A) HK98/H1N1 and (B) VN04/H5N1 was determined after influenza viruses infected in the ud- and wd-NHBE cells from 1 h to 48 h post infection at MOI of 2. (C) The comparison of viral replication kinetic between influenza HK98/H1N1 and VN04/H5N1 viruses in ud- and wd-NHBE at 24 h post infection. The chart showed the mean and the standard error of the virus titer pooled from three independent experiments. Single asterisk indicated statistically significant difference of means with <i>p</i><0.05, double asterisks indicated statistically significant differences of means with <i>p</i><0.01. Dotted line represents the detection limit of the TCID₅₀ assay.</p
