Infection using high MOIs of rSeVCdseGFP or rSeVCeGFP showed more cells infected in SLC35A1 KO cells, and an even larger number in SLC35A2 KO cells at 24hpi, but in both cases the percentage of cells infected was significantly less than controls, suggesting that SeV can enter more cells when used at high MOIs independent of SLC35A1 and SLC35A2 but with limited spread (Fig S3). The gene discussed is SLC35A1; the disease is infection.
