Experimental design. Mice were inoculated intramuscularly (IM) with 107 PFU of 10 poliovirus (PV), six YFV-17D, or nine reovirus (RV) pool members, and tissues were collected at 72 hpi unless otherwise indicated. Muscle damage was induced in a subset of mice before, during, and after viral inoculation to stimulate retrograde axonal transport in the sciatic nerve.
