* Sera were harvested 14 dpi. Cross-reactivity was measured by HI assay except when tested against APMV-5, in which case a plaque neutralization assay was used. HI titers represent the highest dilution that displayed HI activity, and are expressed in mean HI units. For APMV-5, the 70% plaque reduction titer is shown as the mean.
