Figure 4From: Evaluation of immunogenicity and cross-reactive responses of vaccines prepared from two chimeric serotype O foot-and-mouth disease viruses in pigs and cattleThe survival of suckling mice inoculated with FMDVs. Two-day-old BALB/c suckling mice were inoculated IP with tenfold dilutions of the mutant viruses and the wt virus and observed for 7 days. A The survival rate of suckling mice inoculated with rHN. B The survival rate of suckling mice inoculated with rHN/NXVP1. C The survival rate of suckling mice inoculated with rHN/TURVP1. (black filled circle) Dilution of 10–5, (black filled square) dilution of 10–6, (black filled triangle) dilution of 10–7, (black filled inverted triangle) dilution of 10–8.Back to article page
