Tsuneki-Tokunaga A, Kanai K, Itagaki A, Tsuchie H,. Growth capability of epidemic influenza viruses in Japan since the 2009 H1N1 pandemic. Arch Virol. 2021 Feb 12
Abstract
The correlation of viral growth capability (n = 156) with the viral load in nasopharyngeal swabs (n = 76) was assessed. Epidemic influenza A/H1N1, A/H3N2, and B viruses showed a wide range of growth capability (104-1011 copies/mL) in Madin-Darby canine kidney cells. The growth was correlated with the nasopharyngeal viral load (r = 0.53). Six selected strains showed growth-dependent cell death (r = 0.96) in a growth kinetics assay. Epidemic influenza viruses exhibit a wide range of growth capability. Growth capability should be considered one of the key factors in disease prognosis
