BTV viral proteins in tissue sections of sheep skin at different time points pi with BTV-2. A1/A2: BTV protein VP7 in the lumen and endothelium of a blood vessel of the skin at 6 dpi. Leukocytes (characterised as CD45+/mAb151-red) are also present around the blood vessel. Scale bar: 40 μm. B1/B2: BTV proteins NS2 (ORAB53-red) and VP7 (ORAB36-green) in capillaries around glands in the skin at 6 dpi. Scale bar: 40 μm. C1/C2: BTV protein NS2 (ORAB53- green) present around a gland and in leukocytes (CD45+/mAb151-red) of the skin at 6 dpi. Scale bar: 40 μm.
