[Change in the antigenic structure of surface glycoprotein E of tick-borne encephalitis virus during its adaptation to ticks and mammals].

Enzyme immunoassay and immunoprecipitation test of viral proteins, by applying a tick-borne encephalitis (TBE) viral protein E monoclonal antibody kit, have shown that TBE adaptation to ticks and mammals may cause a considerable change in the antigenic structure of surface glycoprotein E, by involving different antigenic domains, including a neutralizing epitope that seems to participate at the early stages of interaction of virions with the cell membrane.
