Figure 2From: Modes of transmission and genetic diversity of foamy viruses in a Macaca tonkeanacolonyImmunofluorescence and electron microscopy of SFV infected cells. A. Typical multinucleated giant cells with a clear seroreactivity of MtoT1 antigens, using an immunofluorescence assay with a positive anti-foamy serum, on BHK-21 infected cells. B. Electron microscopy of ultra-thin sections from cells infected by MtoTF2. The typical foamy viral particles showed a spherical central core and several envelope spikes. The budding observed here is from the cellular membraneBack to article page
