  • a Cells were transfected with an HEV replicon encoding GFP, and the proportion of cells producing GFP and the GFP fluorescence intensity were estimated on a scale of 0 to 4.

  • b Five days after cultures were incubated with a human stool suspension containing HEV, the cells were stained with anti-ORF2 protein for immunofluorescence microscopy, and the number of cells containing ORF2 capsid protein was tallied.
