病原 1977年意大利学者Rizzetto在HBsAg携带者的肝细胞核内,发现了与乙型肝炎的三个抗原不同的抗原物质,当时被认为是第四种抗原,故按希腊字母顺序排列,定名为δ抗原,其相应抗体称为抗-δ。通过近年来的研究确定,它是一种缺陷病毒,有传染性,故又称之为δ因子。为了有别于甲型肝炎、乙型肝炎及非甲非乙型肝炎,将δ因子所感染的肝炎称之为丁型肝炎,δ因子称为丁型肝炎病毒(HDV),其抗原称为丁型肝炎抗原(HDAg),相应的抗体称为丁型肝炎抗体(抗-HD)。由于HDV的装配依赖HBsAg的合成,所以HDV一般只能感染HBsAg阳性病人。
Pathogen In 1977 Italian scholar Rizzetto in HBsAg carriers of the liver cell nucleus, and found that three antigens of Hepatitis B antigen antigen, was considered the fourth antigen, it is arranged in alphabetical order, named δ antigen , The corresponding antibody is called anti-delta. Through the research in recent years to determine that it is a defective virus, contagious, it is also known as δ factor. In order to be distinguished from Hepatitis A, Hepatitis B and Non-Hepatitis B, the factor 6 hepatitis is called hepatitis D, the factor delta is called Hepatitis D virus (HDV) and the antigen is called D Hepatitis B antigen (HDAg), the corresponding antibody called hepatitis D antibody (anti-HD). Since HDV assembly relies on the synthesis of HBsAg, HDVs generally only infect HBsAg-positive patients.
