| Virus dose (TCID50/mouse) | No. of survivors/total | Survival (%) | Mean day to death ± SD |
|---|---|---|---|
| 105 | 15/15 | 100.0 | NA |
| 105.5 | 15/15 | 100.0 | NA |
| 106 | 12/15 | 80.0 | 18.5 ± 4.9 |
| 106.5 | 1/15b | 6.7 | 9.1 ± 1.2 |
| 107 | 0/5b | 0.0 | 7.8 ± 1.3 |
a
Mice infected with different virus doses were monitored for 21 days to determine the the number of mice that died and the mean day to death.
b
The number of mice who survived infection differed significantly from that of mock- infected mice (P < 0.05). NA, not applicable.
