Orpheovirus entry in V. vermiformis cells. a SEM at 24 h.p.i showing an Orpheovirus particle attached to a V. vermiformis cell (white arrow). b IF assays at 1 h.p.i. revealed that more than one particle is able to penetrate the host cell. c TEM images at 24 h.p.i demonstrate that the internal particle content is released into the cell cytoplasm through an ostiole located at the apex of the viral particle (white arrow)
