Figure 3From: Kinetics of pulmonary immune cells, antibody responses and their correlations with the viral clearance of influenza A fatal infection in miceThe dynamics of pulmonary viral load and antibody response in lungs and serum in mice after fatal dose (5 × 105p.f.u.) of A/PR/8/34 (H1N1) virus infection per time-point. HI, haemagglutination inhibition assay. Mice without infection were used as the control group. The dotted lines represented the results of control group. I bars represented standard deviations. *p < 0.05, compared with control group.Back to article page
