Figure 2.

Photomicrographs from immunolabeled sections to detect Piry virus antigens in the brain of NBH and ME7 virus infected groups. Virus antigens were indirectly detected as immunostained cell somas and neuronal primary dendrites in the olfactory pathways in both NBH+Py (a) and ME7+Py (b) groups. Note the absence of virus antigens selective immunolabeling in NBH control group (c). We also did not observe any labeling after immunoreaction without anti-Piry polyclonal primary antibody (not illustrated). Scale bar = 25 μm.
