ABSTRACT
Duck Tembusu virus (DTMUV) is aâ¯newly emerging enveloped flavivirus. This study shows the ultrastructure of DTMUV using viral purification, negative staining and electron microscopy. Electron microscopic examinations revealed mature DTMUV particles with 50 to 75 nm in diameter and typical enveloped flavivirus structure that consists of the internal nucleocapsid, an inner layer of lipid bilayer and an external layer of E glycoprotein ectodomain. Particles appear to be mostly spherical. In particular, RNA core is deep colored and dense, both capsid and lipid bilayer are clearly visible, the capsid forms regular hexagon, and E glycoprotein ectodomain forms aâ¯fringe instead of visible spikes. Thus, this report about the clear ultrastructure of the DTMUV particles will be the major driving forces behind structural biology of DTMUV.
