Figure 4: Distance tree created using the NCBI database after searching for Iraqi BPV-1 transforming protein E5. A 100% identity match was found with a BPV-1 E5 protein sequence isolated from a South African sarcoid-affected zebra (accession number ACR09659) and a 98% identity match was found with a BPV-1 E5 protein sequence isolated from an equine sarcoid in the United Kingdom (accession number AAP69967). The tree was created using the neighbor-joining method.
