Four differently expressed genes in both virulent strain and vaccine ILTV infections. Relative expression was compared for four genes between vaccine ILTV infection and that reported for virulent strain ILTV . The blue, red, green and purple bars represent virulent strain at 1 dpi, virulent strain at 3 dpi, vaccine at 1 dpi, and vaccine at 3 dpi for ILTV infections, respectively.
