To counteract the current paradigm that equates the virus with the viral particle (the virion), one of us suggested a few years ago that a virus-infected cell should be considered as a virocell ([1] and references therein) (figure 1). In that perspective, viral factories produced by many viruses infecting eukaryotes could be considered as the nuclei of virocells (figure 1). Until now, it seemed that nucleated virocells were a peculiarity of the eukaryotic world. However, in a recent paper published [...]
