Mortality and virus replication after intranasal NSV infection. LeeEun-Young L. W. SchultzKimberly E. GriffinDiane 2013 <p>(A) 6-9 week-old WTB6 (<i>N</i> = 11), GKO (<i>N</i> = 24) and GRKO (<i>N</i> = 23) mice were infected intranasally with 10<sup>5</sup> pfu NSV and followed daily for mortality which was similar. <i>P</i> = 0.47. At 3, 5, and 7 d after infection, brains (B), cervical (C) and lumbar (D) spinal cords from 3 WTB6, GKO or GRKO mice were assayed for infectious virus by plaque formation on BHK cells. LOD = limit of detection. * <i>P</i> < 0.02; t test.</p>
