Molecular basis for a geographic variation of varicella-zoster virus recognized by a peptide antibody.
A live attenuated varicella vaccine, derived from a Japanese isolate, is currently being widely used to modulate disease caused by varicella-zoster virus. Differentiation of the vaccine from wild-type isolates has been and will continue to be critical in the assessment of the vaccine in the United States. This has largely relied upon identification of characteristic DNA polymorphisms in the vaccine strain in the United States. This has largely relied upon identification of characteristic DNA polymorphisms in the vaccine strain. In this report, we describe the identification of a new sequence polymorphism, located in the N-terminal coding sequence of open reading frame (ORF) 10. This variation results in the synthesis of an ORF 10 protein that is differentially recognized by antibodies to an ORF 10 synthetic peptide. The variation appears to be completely restricted to Japanese strains, including that used for the live attenuated varicella vaccine. As such, this polymorphism and the antibodies that differentially recognize it could prove highly useful in the assessment of the Japanese vaccine in the United States.
