Histological examination of the chorioallantoic membrane after allantoic inoculation of NDV and telomycin mixture in SPF-ECE. A: normal chorionic and allantoic epithelium (arrowhead) with a visible stromal region (star) in telomycin group. B: hyperplastic and vacuolated chorioallantoic epithelium (arrowhead) and increased thickness of connective tissue layer (star) with numerous hyperemic blood vessels (arrow) in the positive control group. C: preserved structures of CAM with the presence of dilated capillary networks (arrow) in NDV and telomycin treated group (H&E X200)
