NCI: A virus that causes hepatitis (inflammation of the liver). It is carried and passed to others through blood or sexual contact. Also, infants born to infected mothers may become infected with the virus.,MSH: The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.,NCI: Hepatitis B Virus (HBV) is the prototype of the Hepadnavirus Family. Included in the family are the Woodchuck Hepatitis Virus (WHV) and the Duck Hepatitis B Virus (DHBV) which provide animal models of infection. The HBV genome is a partially double stranded circular DNA. A viral reverse transcriptase is bound to the 5' extremity of the long strand.
