FIG 3

A synthetic virus with a chimeric BTV-1/BTV-8 VP2 is replication competent and cross-reacts with BTV-1 and BTV-8 antisera. (A) Protein alignment of BTV-1 and BTV-8 VP2. (B) The plaque morphology of parental and chimeric synthetic reassortants [B1BTV-1(BTV-8-220-429)] is shown (left). Neutralization assays (right) of BTV-1, BTV-8, and B1BTV-1(8-VP2-220-429) using BTV-1 and BTV-8 antisera were performed as described in Materials and Methods. BTV-1 and BTV-8 are neutralized only by homologous antisera. On the other hand, B1BTV-1(8-VP2-220-429) is neutralized by both BTV-1 and BTV-8 antisera.
