Morphology of chicken embryo lung cells infected by vaccine ILTV and the expression of ILTV genes. (A) Cell morphology and cytopathic effect development at 0, 1, 2, 3 and 4 dpi are displayed by phase-contrast microscopic images at 200 × magnification. (B) ILTV gene expression for UL35 and US5 was determined by RT-PCR. Chicken GAPDH (chGAPDH) was used as an endogenous control.
