Mortality and viremia levels at terminal point of guinea pigs infected with single or combination point mutant viruses. (A) Mortality of animals infected with single point mutant viruses. Numbers of infected animals: rP18, n = 45, and recombinant mutant viruses, n = 6. (B) Mortality of animals infected with combination point mutant viruses. Numbers of infected animals: rP18, n = 45, and recombinant mutant viruses, n = 6. (C) Viremia levels at terminal points (or end of experiment for recovered animals) of guinea pigs infected with single and combination point mutant viruses. Each data point represents one animal: rP18, n = 29; N1889D mutant, n = 5; all other mutants, n = 6. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
