    摘要： The present invention is a method for detecting hepatitis E virus infection, comprising a detection step of detecting anti-hepatitis E virus antibodies in a sample by using, as an antigen polypeptide, at least one polypeptide selected from the group consisting of the following (a) to (c):
    (a) a polypeptide consisting of an amino acid sequence which includes amino acids located at position 28 to 175 in the amino acid sequence set forth in any one of SEQ ID NOs: 1 to 4 and which has a full length of 200 residues or less that are contained in the amino acid sequence set forth in the sequence number;
    (b) a polypeptide consisting of an amino acid sequence in which one or more amino acids are substituted, deleted, inserted, and/or added in the amino acid sequence which includes amino acids located at position 28 to 175 in the amino acid sequence set forth in any one of SEQ ID NOs: 1 to 4 and which has a full length of 200 residues or less that are contained in the amino acid sequence set forth in the sequence number; and
    (c) a polypeptide consisting of an amino acid sequence having 80% or more homology with the amino acid sequence which contains amino acids located at position 28 to 175 in the amino acid sequence set forth in any one of SEQ ID NOs: 1 to 4 and which has a full length of 200 residues or less that are contained in the amino acid sequence set forth in the sequence number.

    摘要： The present invention relates generally to viral variants exhibiting reduced sensitivity to agents such as nucleoside or nucleotide analogs or other DNA polymerase antagonists and/or reduced interactivity with immunological reagents. More particularly, the present invention is directed to hepatitis B virus (HBV) variants exhibiting complete or partial resistance to nucleoside or nucleotide analogs or other DNA polymerase antagonists and/or reduced interactivity with antibodies to viral surface components including reduced sensitivity to these antibodies. The present invention further contemplates assays for detecting such viral variants, which assays are useful in monitoring anti-viral therapeutic regimens and in developing new or modified vaccines directed against viral agents and in particular HBV variants. The present invention also contemplates the use of the viral variants to screen for and/or develop or design agents capable of inhibiting infection, replication and/or release of the virus.
