From: Generation and characterization of UL41 null pseudorabies virus variant in vitro and in vivo
Survival percentages of mice. Mice were intranasally inoculated with 105 TCID50 (Top) and 104 TCID50 (Bottom) of JS-2012, UL41 revertant virus and UL41 null virus. Mice were observed every day and for a maximum of 10 days. The statistical significance between survival curves was evaluated by the log-rank (Mantel-Cox) test. P value < 0.05 was considered statistically significant, and *P < 0.05, **P < 0.01, ns was refered as no significance
