Inhibition of the replication of the Zaire species of Ebola virus (ZEBOV) in Vero cells, as demonstrated by immunofluorescence staining. Cells were transfected with either a pool of 4 different small interfering RNAs (siRNAs) targeting individual regions of the ZEBOV polymerase (L) gene or an equivalent dose of EbL-Scram1, an irrelevant scrambled sequence (SCR), as a control. Cells were counterstained with 4′,6′-diamidino-2-phenylindole and Evans blue, to aid visualization. ZEBOV-positive cells are identified by green fluorescence
