Ten recombinants between the viruses of vaccinia and ectromelia were isolated that cause the ectromelia virus specific lesions in mice. The structure of recombinant viral genomes, the efficiency of viral propagation in mice, the nature of lesions induced by viruses have been studied. Eight of obtained recombinants have a DNA insertion originating from the right end of ectromelia viral genome, nine recombinants have an insertion originating from the left end, seven recombinants possess both insertions. The latter recombinants have more pronounced pathogenicity for mice. Both revealed regions are supposed to define the specific pathogenicity of ectromelia virus for mice.
