FIG. 5.

SIEM of the mid-region of axons in the OC of the model, fixed 24 h after virus was inoculated into the IC. (A) Colocalization of 10-nm immunogold labelling VP5 and 20-nm immunogold labelling VP16. The 10- and 20-nm labels are intermingled within 150 nm of each other. Bar, 100 nm. (B) Dually labelled axons for VP5 and gC, but showing only the 30-nm immunolabel for gC since there was no colocalization with the 10-nm immunogold label for VP5. In fact, immunolabels for VP5 and glycoproteins could not usually be observed in the same high-power field. Note the small diameter of some axon fascicles. Bar, 100 nm.
