differences in ibaraki virus rna segment 3 sequences from three epidemics.phylogenetic tree and partial nucleotide sequence analysis of rna segment 3 were conducted to compare the ibaraki virus (ibav) strains from three epidemics in japan, and serotype 2 epizootic hemorrhagic disease virus strains isolated in australia, taiwan, and canada. each strain was classified relative to the ibaraki disease (ibad) epidemics, which occurred in 1959-1960, 1987, or 1997-1998. in particular, major variation of the gene was identified in the strains isolated after 1997 when a new ty ...200314665759
