δ肝炎病毒(HDV)是一种新近发现的能引起人类肝炎的病原体。其组成:核心含有单股病毒RNA,整个外周为HBsAg所包围,因此,它是一种杂合结构。由于这种杂合结构,HDV复制和表达则需HBV伴行存在。鉴于HDV的独特结构,HDV感染可与HBV感染同时发生(联合感染)或重叠感染于慢性HBV感染。重要的是HDV感染不可能
Delta Hepatitis virus (HDV) is a newly discovered causative agent of human hepatitis. Its composition: the core contains a single viral RNA, the entire periphery is surrounded by HBsAg, therefore, it is a hybrid structure. Due to this heterozygous structure, replication and expression of HDV requires the presence of HBV partners. In view of the unique structure of HDV, HDV infection can occur concurrently with HBV infection (co-infection) or with overlapping infection in chronic HBV infection. It is important that HDV infection is not possible
