Fig. 5. Replication kinetics of European swine influenza viruses in different cell lines. Growth curves were obtained by inoculating cells at m.o.i. 0.01 p.f.u. per cell with H1N2, H1avN2hu, H1pdmN2sw or H3N2. Supernatant was harvested and titrated in MDCK cells at 8, 10, 12, 18, 20, 24, 36, 48 and 60 h p.i. Data are expressed as mean±sem log10TCID50 from two independent experiments titrated in quadruplicate.
