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

aAll 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.bRoute of inoculation. i.n., intranasal (106 EID50/ml) unless otherwise specified; i.o.; ocular inoculation (106 EID50/100 µl).ci.o. NW and RS samples are inclusive of 6 ferrets tested.dViral titers represent a pooled intestinal sample consisting of the duodenum, jejuno-ileal loop, and descending colon.eIntranasal inoculation performed using 106 EID50/100 µl virus dose.fND, not detected.
