自1977年Rizzetto报告了抗原抗体系统,各国学者均进行了广泛深入的研究,1984年建议命名为肝炎,国内叫做丁型肝炎。 肝炎病毒是一种有缺陷的病毒,必需在乙型肝炎病毒或其它肝DNA病毒辅助下,才能进行复制,它只见于HBsAg阳性的肝细胞核或血清中。肝炎病毒具有完整的病毒结构,直径为35～37毫微米,它的外壳为HBsAg,核心是一个低分子的核糖核酸。目前已知肝炎病毒只有一个血清型。肝炎病毒感染可抑制乙型肝炎病毒的合成。当肝炎病毒在体内增加时,乙型肝炎病毒就减少。肝炎病毒消失,就出现抗肝炎病毒抗体。肝炎病毒可感染黑猩猩和美洲旱獭,并能使其发病。
Since Rizzetto reported the antigen-antibody system in 1977, scholars from all over the world conducted extensive and in-depth studies. In 1984, it was suggested that it be named hepatitis and hepatitis D was called domestic. Hepatitis virus is a defective virus that must be replicated with the aid of Hepatitis B virus or other hepadnavirus and found only in the nuclei or serum of HBsAg-positive hepatocytes. Hepatitis virus has a complete virus structure, a diameter of 35 to 37 nm, its shell is HBsAg, the core is a low-molecular-weight ribonucleic acid. It is known that there is only one serotype of hepatitis virus. Hepatitis virus infection can inhibit the synthesis of hepatitis B virus. Hepatitis B virus decreases as hepatitis virus increases in the body. Hepatitis virus disappears, appeared anti-hepatitis virus antibodies. Hepatitis viruses can infect and make chimpanzees and Marmota.
