hepatitis B

hepatitis B
Virion (Dane particle), 42nm diameter, with an outer sheath enclosing inner 27nm core particle containing the circular viral DNA. Aggregates of the envelope proteins are found in plasma and are referred to as hepatitis B surface antigen (HBsAg; previously called Australia antigen). Causes "serum hepatitis"; virus can persist for long periods (and in asymptomatic carriers) ; association of integrated virus with hepatocellular carcinoma is now well established.
