Hepatitis B virus -LRB- HBV -RRB- is an example of a helper virus that helps Hepatitis D virus -LRB- HDV -RRB- -LRB- a replication defective , helper dependent ssRNA virus -RRB- to replicate -- as HDV requires the surface antigen of HBV -LRB- HBsAg -RRB- for the encapsidation of its own genome .. genome. genome. HBsAg. HBsAg. The envelope proteins on the outer surface of HDV are entirely provided by HBV .
