Figure 4

Flu A/Pdm H1N1 09, Flu A/H3N2, and Flu B/Yamagata viruses induce cell death and apoptosis profiles. Effects of influenza infection (MOI 1.0) on viability of MDCK II (a), and A549 cells (b) were determined by LDH assay. The indicates significant differences () and from the mock cells at the same time after infection.

(a) MDCK II

(b) A549
