Passatempo Virus, a Vaccinia Virus Strain, Brazil
Figure A2
![Electron micrographs of cells infected with Passatempo virus. Vero cells were infected with Passatempo virus at a multiplicity of infection of 5 and fixed by OsO4, 24 hours after inoculation. 1, typical orthopoxvirus "brick-shaped" morphologic pattern, with biconcave core and outer membranes were observed in cell-associated enveloped virus (CEV); 2, intracelullar mature virions (IMV) were visualized in the cytoplasm of infected cells within virosomes with the presence of spheric immature virus (](/eid/images/05-0773-FA2.jpg)

No A-type inclusion body (ATI) was visualized in infected cells. N, nucleus. Bars, 500 nm.
