| 摘要 |
The present invention describes recombinant RV mutants comprising a combine mutation in two different parts of the viral genome, involving the P and the G genes. The mutations in the P gene preferably encompass residues 139 to 170, more preferably residue 139 to 149, most preferably residues 143-149. The mutation can be a substitution or deletion of one or more amino acids in the above region, as well as combinations of deletion and substitution.
