Moreover, no viral RNA could be detected in blood of these immunized sheep except for day 5 post-infection, when Ct levels of these animals were significantly (P value  <  0.002) lower compared to the control group (MVA/MVA-VP2-NS1-2A-NS2-Nt Ct value mean = 33.515; Control Ct value mean = 26.8975) (Figure 5E). The gene discussed is LZTR1; the disease is infection.
