Figure 3From: Genomic analysis of bluetongue virus episystems in Australia and Indonesia Genome segment sharing between Indonesian and northern Australian BTV isolates. Year(s) of circulation are shown in parentheses and presumed reassortment events are indicated with an arrow. A The replacement of the existing Australian BTV-1 lineage from 1989 to 1993 (blue blocks) with segments circulating in concurrent Indonesian viruses (red blocks) is shown. B The introduction of BTV-2 into Australia and subsequent reassortment with BTV-1 viruses is shown. BTV-2 segments also circulating in concurrent Indonesian BTVs are indicated in red, segments unrelated to others in our dataset are shown in yellow, and pre-existing Australian BTV-1 segments are indicated in blue.Back to article page
