Figure 2From: Transmissibility studies of vacuolar changes in the rostral colliculus of pigsAbsence of disease-specific immunolabelling in an un-inoculated pig. Serial coronal sections (A and B) of rostral midbrain (oculomotor nerve nucleus) of pig PR459. A) Absence of any labelling. Immunolabelling with mAb 2G11. B) Presence of disease-unspecific labelling of neuronal perikarya with mAb L42.Back to article page
