Figure 7From: UL28 and UL33 homologs of Marek’s disease virus terminase complex involved in the regulation of cleavage and packaging of viral DNA are indispensable for replication in cultured cellsElectron microscopy examination of parental virus-infected or DNA of MDV △UL28-transfected CEF cells. A CEF cells were infected with parental virus or transfected with DNA of MDV △UL28, and fixed at 3 days post-infection/transfection. The electron microscopic examination indicated that mature and immature virions were formed. The mature virions were marked with a red arrow, while immature virions were marked with a black arrow; B CEF cells were transfected with DNA of MDV △UL28, and fixed at 3 days post-transfection. The electron microscopic examination revealed that immature capsids were formed and marked with a black arrow. The scale bar is 500 nm.Back to article page
