Figure 6. The neutralizing titer of systemic influenza-specific antibody is similar in adult and infant animals.
Neutralizing antibody titer in the plasma of infected infant and adult animals was assessed at d8 and d14 p.i. Neutralization capacity was determined by inhibition of infectivity of a GFP expressing influenza virus. The neutralization titer was defined as the dilution at which infectivity of the virus was inhibited by 50%. Significance at each timepoint was determined using a Mann Whitney test. * p≤0.05.
