δ因子是存在于急性感染期血清中的一种直径36nm的颗粒。它由δ抗原和一种被HBsAg包裹的1.75 Kb RNA(DAR)所组成。在肝活检中δ抗原的持续表达是慢性δ感染的最可靠的标志。虽然慢性delta携带
The delta factor is a 36nm diameter particle present in the sera during acute infection. It consists of a delta antigen and a 1.75 Kb RNA (DAR) encapsulated in HBsAg. The continuous expression of delta antigens in liver biopsies is the most reliable marker of chronic delta infection. Although chronic delta carries
