Neighbor-Joining tree was constructed based on partial sequencing of the gB gene showing the genetic relatedness of our Egyptian isolate (OM803183) to other reference strains from GenBank. Our isolate showed 100% homology to BoHV1.1 reference strains Including Egyptian BoHV-1.1 reference strains (blue circle) with query coverage 63% but away from BoHV-5, which are located in a separate clade.
