From: Analysis of PERV-C superinfection resistance using HA-tagged viruses
Electron microscopy of PERV-C virus particles in transfected ST-IOWA cells. A, B PERV-C(5683) particles, C, D virus in ST-IOWA cells transfected with SP-HA, E, F viral particles in ST-IOWA cells transfected with RPep-HA. Virions are indicated by black arrow heads. All viral particles show an identical morphology with a dense, collapsed core surrounded by evenly rounded capsids
