Mortality and tumor incidence in chickens infected with recombinant MDVs. (A) Survival rate in chickens infected with recombinant Marek’s disease viruses (rMDVs). Asterisks indicate significant differences. (** p < 0.01, * p < 0.05; log-rank test). (B) Tumor incidence in chickens infected with rMDVs throughout the study period. Asterisks indicate significant differences (** p < 0.01, * p < 0.05; Fisher’s exact test). The viral loads in (C) peripheral blood mononuclear cells, (D) spleens, and (E) feather tips from chickens infected with the rMDVs were determined by quantitative polymerase chain reaction. Asterisks indicate significant differences (** p < 0.01; Kruskal–Wallis test).
