Perfringolysin O activities of various C. perfringens strains
| Strain | Genotype | Perfringolysin O titer (log2)a | Difference (fold) compared to strain 13 |
|---|---|---|---|
| 13 | Wild type | 7.4 ± 0.5 | 1 |
| TS133 | Strain 13 virR::Tetr | 2.0 ± 0.1 | <0.1 |
| TS190 | Strain 13 ΔvirT | 9.4 ± 0.5 | 3.9 |
| TS190(pTS930) | Strain 13 ΔvirT (virT+) | 7.7 ± 0.4 | 1.2 |
| 13(pTS931) | Strain 13 (virU+) | 9.5 ± 0.7 | 4.3 |
Each value was calculated by using the results of triplicate independent experiments, and the values are means ± standard deviations.
