Abbreviations: hemagglutination inhibition, HAI; keyhole limpet hemocyanin, KLH.

No significant difference in HAI activity was detected between antiserum and pre-immune serum.

Significant difference in HAI activity was detected between antiserum and pre-immune serum from mice given virus immunogens (*P<0.05).
