摘要： The present invention provides the genes encoding the following BRV proteins: for group A, the VP4 and VP7 proteins of the Indiana (IND) strain, and the VP7 protein of the 2292B strain; for group B, the VP7 protein of the WD653 strain; for group C, the VP4 and VP7 proteins of the Shintoku strain. The genes are useful for producing nucleic acid probes which are complementary to the VP7 and VP4 genes. Such probes are useful for detecting the presence of group A,B, and C BRV in fecal samples from diarrheic calves and for determining the serotype of the BRV field isolates. The genes are also useful for producing partial length nucleic acid probes which are complementary to hypervariable regions of the VP4 and VP7 genes. The present invention also relates to partially purified VP2, VP4, VP6 and VP7 proteins of the IND strain and VP4 and VP7 of the 2292B strain, the partially purified VP7 protein of the WD653 strain, and partially purified VP2, VP4 and VP7 proteins of the Shintoku strain. The present invention also relates to recombinant virus-like particles (VLPs) which comprise one or more of the VP2, VP4, VP6, and VP7 proteins of the BRV strains IND, 2292B, CR, WD653, and Shintoku.
