TABLE 1.
Morbidity and mortality rates of mice inoculated with each virus via the i.c. or i.m. route
| Strain | % Morbidity (i.c.; no. sick/inoculated) | % Mortality (i.c.; no. dead/inoculated) | % Morbidity (i.m.; no. sick/inoculated) | % Mortality (i.m.; no. dead/inoculated) |
|---|---|---|---|---|
| Mocka | 0 (0/5) | 0 (0/5) | 0 (0/5) | 0 (0/5) |
| CE(NiP)b | 100 (20/20) | 100 (20/20) | 80 (16/20) | 80 (16/20) |
| CE(NiP)ΔP2-5b | 100 (20/20) | 100 (20/20) | 35c (7/20) | 30c (6/20) |
a
A group of 5 mice was inoculated with a diluent.
b
Groups of 20 mice were inoculated with each virus.
c
P value of <0.01 compared to the CE(NiP) strain group by Fisher's exact test.
