Serological diagnosis with recombinant N antigen for hantavirus infection

摘要

Hantaviruses are causative agents of two rodent-borne zoonoses, hemorrhagic fever with renal syndrome (HFRS) and nephropathia epidemica (NE) in the Old World and hantavirus pulmonary syndrome (HPS) in the New World. Serological examinations to detect hantavirus antibodies have been most widely used for surveillance among humans and rodent reservoirs. Here, we will review antigenic structure of nucleocapsid (N) protein of hantaviruses and application of recombinant N protein as diagnostic antigen for screening and serotyping.
