Bovine rotavirus 993/83 shows a third subtype of avian VP7 protein.
VP7 genes of rotavirus (RV) 993/83 isolated from a German calf with diarrhea and of RV PO-13 isolated from a Japanese pigeon were sequenced. Alignment of the deduced VP7 amino acid sequence showed 98.8% sequence identity, while only 70% and 84% identity was seen with VP7 from chicken RV Ch-2 and turkey RV Ty-1, respectively. Over the antigenic regions A, B, and C mammalian RV 993/83 showed more aa identity with mammalian G3 RVs than with chicken RV Ch-2, which could explain the strong one-way cross-neutralization observed between RV 993/83 and G3 RVs. Despite marked VP7 sequence diversity avian RVs could not be differentiated into distinct G types.
