Figure 5From: Duck plague virus tegument protein vp22 plays a key role in the secondary envelopment and cell-to-cell spread Electron microscopy analysis BAC-CHv, BAC-CHv-ΔUL49 or BAC-CHv-UL49R infected DEF cells. A–C The electron microscopic pictures of DEF cells infected with BAC-CHv, BAC-CHv-ΔUL49, and BAC-CHv-UL49R were presented. D–E A close-up of the zoomed area shows virions in the cytoplasm of BAC-CHv, BAC-CHv-ΔUL49, or BAC-CHv-UL49R infected cells. The nucleus (N) and cytoplasm C are marked.Back to article page
