BTV viral proteins in tissue sections of other sheep organs at different time points pi with BTV-2. A1/A2: BTV protein NS2 (ORAB53- green) in the endothelium of a capillary in the dermis underneath the epithelium of the labia at 6 dpi. Vimentin, a member of the intermediate filament family commonly used as marker for mesodermally derived tissues, is shown in red to demonstrate the dermal layer in contrast to the epithelium (which does not contain vimentin). Scale bar: 40 μm. B1/B2: BTV protein VP7 (ORAB36-green) in the endothelium of capillaries between muscle blocks of the tongue at 4 dpi. Scale bar: 20 μm. C1/C2: BTV protein VP7 (ORAB36-green) in the endothelium of small blood vessels in the dermis of the skin at 6 dpi. Scale bar: 40 μm.
