Growth kinetics of type A and D influenza viruses in MK1-OSU, SD-PJEC, and MDCK cells. Growth kinetics of type A and D influenza viruses during 72 h post-infection were measured in MK1-OSU, SD-PJEC, and MDCK cells. Briefly, cells were infected with the influenza viruses at MOI of 0.01 and 100 µL of media was sampled at 12 h intervals until 72 h. Viral 50% infective doses were expressed as log₁₀ TCID₅₀/mL. Values represent the mean ± SE of three experiments for (A) pdm09/CA04, (B) MN08, (C) IA07, (D) DOK, (E) FL06, and (F) BR08.
