TABLE 3.
Expression factors of the icaA gene of the hemB mutant compared to the wild-type strain at time points T1 to T5
| Time point | Expression factor (mean ± SD)a
|
|
|---|---|---|
| icaA | asp23 | |
| T1 | 10.9 ± 3.0 | 20.8 ± 2.6 |
| T2 | 22.2 ± 6.7 | 20.8 ± 6.1 |
| T3 | NDb | 0.8c ± 0.6 |
| T4 | 4.4 ± 1.3 | 2.6 ± 0.4 |
| T5 | NDb | 0.26c ± 0.04 |
a
Calculated factors are means from at least two independent RNA preparations from the hemB mutant and the wild type.
b
ND; no transcript of icaA detected in the wild-type strain.
c
An expression factor of <1 indicates down-regulation.
