Fig. 4From: Recombinant pseudorabies virus with gI/gE deletion generated by overlapping polymerase chain reaction and homologous recombination technology induces protection against the PRV variant PRV-GD2013Pathogenic testing in piglets using recombinant PRVs. a Rectal temperature of piglets after inoculation with PRV-GD2013, PRV-GD2013-ΔgI/gE, or DMEM. b gB-specific antibody levels. Sample with S/N ratios ≤0.60, were classified as positive for gB antibodies. c Detection of gE-specific antibody levels. Samples with S/N ratios ≤0.60 were classified as positive for gE antibodies. All data are presented as the mean ± SDBack to article page
