TABLE 1.
Survival times and levels of bacteremia in mice infected intranasally
| Bacterial strain | Survival time (h)a | Mean ± SEM log CFU/ml at the following h postchallengeb:
|
|||
|---|---|---|---|---|---|
| 0 | 6 | 12 | 24 | ||
| D39 | 34 | NF | NF | 3.20 ± 0.70 | 5.76 ± 1.02 |
| aliA | 46.5 | ||||
| aliB | 46.5 | ||||
| amiA | 34 | ||||
| aliA aliB | 34 | ||||
| aliB amiA | 34 | ||||
| aliA amiA | 34 | ||||
| obl | 34 | NF | 2.01 ± 0.98 | 4.21 ± 0.62 | 4.66 ± 0.87 |
a
Median survival times of 5 or 10 mice intranasally infected with 106 CFU of D39 or various mutants.
b
Levels of bacteremia following intranasal infection of five mice with either D39 or the obl mutant were similar. NF, none found.
