In chickens vaccinated with MDV strain CVI 988, HVT strain FC 126 or PB-THV 1, no MDV-specific antigens could be demonstrated in the feather follicle epithelium by immunofluorescence (IF). In chickens given virulent MDV strains, the epithelium of the feather follicle was positive in IF. In an experiment where chickens were vaccinated with strain CVI 988, positive IF was observed in the lung, bursa and pancreas, but not in the feather follicle epithelium, kidney, cloaca, or caecal tonsils. Absence of IF antigen in the skin may be indicative of avirulence of the strain of MDV.
