Eight basic characteristics of equine circovirus, Berne virus, human circovirus, porcine circovirus and coronavirus. Coronaviridae are spherical or polygonal particles with a diameter of 80-220nm. There are 2-3 kinds of glycoprotein protrusions on the surface of the capsule, one of which is a long cup-shaped protrusion with a length of 20nm. The nucleocapsid is a tubular coiled helix with a diameter of about 9- 10 nm. Virus particles do not contain RNA polymerase, but have a small amount of protein kinase. It is not clear whether this protein kinase is encoded by virus or host cell.
