Comparative viral pathogenesis between intranasal and ocular inoculation day 3 p.i. in extra-ocular tissue.

a<p>All viral titers expressed per gram of tissue except NW, NT, and RS samples which are expressed per ml. Limit of detection is 1.5 log₁₀ EID₅₀. The mean viral titer of all ferrets with positive virus isolation (denoted in parentheses) is shown.</p>b<p>Route of inoculation. i.n., intranasal (10⁶ EID₅₀/ml) unless otherwise specified; i.o.; ocular inoculation (10⁶ EID₅₀/100 µl).</p>c<p>i.o. NW and RS samples are inclusive of 6 ferrets tested.</p>d<p>Viral titers represent a pooled intestinal sample consisting of the duodenum, jejuno-ileal loop, and descending colon.</p>e<p>Intranasal inoculation performed using 10⁶ EID₅₀/100 µl virus dose.</p>f<p>ND, not detected.
