Intranuclear virus-like particles in a case of sporadic non-A, non-B hepatitis

A case of acute hepatitis type non-A, non-B in a 20-year-old woman is reported. Virus-like particles with a size of about 27 nm in diameter could be identified by electron microscopy in numerous hepatocellular nuclei. They are thought to represent one candidate for the intranuclear form of a non-A, non-B hepatitis virus.
