FIG. 3.

Counts of the number of infected neurons in various brain regions of moribund mice (9 to 21 days p.i.) that received daily treatment with vehicle (n = 9) or minocycline (n = 12). Slides stained for rabies virus antigen were masked, and the numbers of infected neurons in three different fields of the same brain region were counted using a high-power (40×) objective for areas with the most marked staining. *, statistical significance at a P of <0.05 determined using an unpaired t test. Error bars represent the standard errors of the means for comparisons of values for treatments with vehicle versus minocycline.
