Herpesvirus-like particles in epithelial cell of a harbor porpoise with
herpesvirus type 1 infection. Genital mucosa of harbor porpoise #6 infected with Phocoena phocoena herpesvirus type 1, a gammaherpesvirus. Transmission electron micrographs of an epithelial cell, stained with uranyl acetate and lead citrate. The nucleus of the epithelial cell has electron-dense clumps of marginated chromatin and contains an intranuclear inclusion body. Within this inclusion body, there are round to hexagonal unenveloped viral nucleocapsids, some with an electron-dense core (inset). Bar of inset = 200 nm.
