Kiyotani et al. Arch. Virol. 146:893-908, 2001). One of the clones, E15cl2, which was obtained from the virus at the 15th egg passage of E0, the parental Hamamatsu clone for egg passage, had 165-fold-attenuated virulence to mice and possessed only four mutations in the entire 15,384-base genome: in an antigenomic sense, U to A at position 20 (U20A) and U to A at position 24 (U24A) in the leader sequence, the promoter for transcription and replication, and A to G at position 9346 (silent) and A to U at position 12174 (Ser to Cys) in the L gene. To examine the possibility that leader mutations affect virus pathogenesis, we recovered live viruses from cDNA derived from the Hamamatsu strain. A mutant virus possessing either a mutation of U20A or U24A in the leader sequence showed a slightly lower pathogenicity than that of the parental virus, whereas a double mutant virus possessing both of the mutations showed 25-fold-attenuated virulence, accompanying a significantly lower virus replication in the mouse lung. Replications of the leader mutant viruses were also impaired in a primary culture of mouse pulmonary epithelial cells but not in chicken embryo fibroblasts. These findings suggest that leader mutations of SeV affect virus pathogenesis by altering virus replication in a host-dependent manner."xsd:string |
