TABLE 1.
Number of viable S. flexneri recovered from the lungs of mice inoculated with 1 × 107 to 2 × 107 SSW202 or 2457T
| Day post-inoculation | CFUs of S. flexneri (no. of mice)
|
P value | |
|---|---|---|---|
| SSW202 | 2457T | ||
| 1 | 1.6 × 106 (6) | 1.1 × 108 (3) | 0.0004a |
| 3 | 2.2 × 104 (4) | 4.1 × 106 (4) | 0.012a |
| 5 | 7.8 × 102 (4) | n/ab (4) | 0.029c |
a
P value comparing CFU counts was calculated using the independent Student’s t test.
b
n/a, not applicable.
c
P value comparing alive versus dead mice was calculated using the Fisher’s exact test.
