Summary

Avian infectious honchit viruses (ISV) isolated in Taiwan in 2033 and 18 live vaccine viruses were studier! with reverse transcriptase polyrnerase chain reaction (RTPCR) and subnent serjuence analysis of the region of 1,1CC nucleotides covering the spike 1(S1) uotein highly variant region gene. Both genetic and antigenic heterogeneity of the strains was siguificant. SthficaUy, asxording to phylogenetic analyses Which there axe three genetic groups are to distinguish with other isolates in the work), one genetic group axe dosed to the isolated from China, and one virus isolaal is nature xaornbination from Taiwan genetic group I with China genetic group.
