Figure 3. Deduced amino acid sequences of the VP7 antigenic regions of rotavirus G9P strains. A) Outbreak strains. B) Nonoutbreak strains. The VP7 sequences of the standard G9 strain (US1206) and the Australian nonoutbreak strains were obtained from GenBank. Accession numbers are as indicated: US1206: AJ250271, Perth G9.1: AY307094, Syd-G9.1: AY307093, MG9.06: AY307085, Melb-G9.21: AY307090. The sequence of rotavirus strains F45 was obtained from Kirkwood et al. (33). All other sequences were determined in this study. A dash indicates homology with the US1206 sequence at that position.
