Comparative analysis of the viruses and pp by hemagglutination inhibition testing and ELISA-, CPE-, and fluorescence-based microneutralization assays.

aFor the hemagglutination inhibition test, the titers of the virus and pp were adjusted to 4 hemagglutination units.
bFor the microneutralization assays, the titers of the virus and pp were adjusted to 100 TCID50. The 95% inhibitory concentration (IC95) was used for nAb analysis.
cTiters are presented as the average ± standard deviation. All tests were repeated three times.
