FIG. 4.

Ultrastructural analysis of INT, NMP, and pnHSV fractions. (A) The INT contains mature virions and membranous structures. (B) The NMP shows primary enveloped virions, membranes, partially enveloped capsids, and naked capsids. (C to E) pnHSV-1. Images at the ultrastructural level show both intact (black arrowheads) and partially damaged (open arrowheads) primary enveloped virions. Also visible are both immature and mature HSV-1 capsids (asterisk). Bars, 500 nm (A) and 200 nm (B to E).
