Cytopathic effect, electron micrograph, and genome electrophoresis of SMReV. (A) Cytopathic effect (CPE) induced by SMReV in GCF cell lines. Arrow indicated the syncytial. (×100). (B) Negatively stained virions. The bars represent 100 nm. (C) Purified genomic dsRNA of SMReV was analyzed by 1% agarose gel electrophoresis. Genomic dsRNA of GCRV-873 was used as control.
