Novel isolated and purified strains of Chikungunya virus and polynucleotides and polypeptides sequences, diagnostic and immunogenical uses thereof

摘要

The present invention concerns wild-strains of Chikungunya virus isolated from patients exhibiting severe forms of infection and stemming from a human arbovirosis epidemy. The present invention also concerns polypeptide sequences and fragment thereof derived from their genome, the polynucleotide encoding same and their use as diagnostic products, as vaccine and/or as immunogenic compositions.
