Electron microscopy of ORFV strain NA1/11. OFTu cells were infected with NA1/11. After 24 h, cells harvested and fixed for embedding were prepared for transmission electron microscopy as described under Materials and Methods. Fields show predominantly immature virions (A), intracellular mature virions (B) and extracellular virions under atomic force microscopy (C). Scale bars = 500 nm.
