Rotavirus strains collected in the United Kingdom during the
1995-1996 season and genotyped as G2 by reverse
transcription-PCR failed to serotype in enzyme-linked immunosorbent
assays using three different G2-specific monoclonal antibodies. The
deduced amino acid sequences of the antigenic regions A (amino acids 87 to 101), B (amino acids 142 to 152), and C (amino acids 208 to 221) of
VP7 revealed that a substitution at position 96 (Asp
Asn) correlated
with the change in ability to serotype these G2 strains.
