Additional file 1: Figure S1 Construction of recombinant FHV WX19 with deletion of the gI, gE, and TK genes. A: presence of gI/E, fragment in the parenteral FHV by PCR, deletion and replacement of the counterpart by eGFP in the FHV-ΔgI/E- eGFP and FHV ΔgIgE/TK eGFP–mCherry. B: presence of TK, fragment in the parenteral FHV by PCR, deletion and replacement of the counterpart by eGFP in the FHV-ΔTK-mCherry and FHV ΔgIgE/TK eGFP–mCherry.
