| Strain | 9602WT-lux | 9602P-lux ± PA | 9602C-lux ± EF | 9602L-lux ± LF | 9602LC ± LF, EF |
|---|---|---|---|---|---|
| CFU (log10/mL) | 5.04 ± 0.14 (5) | 5.06 ± 0.31 (12) | 5.13 ± 0.34 (7) | 5.4 ± 0.29 (6) | 4.3 ± 0.26 (5) |
Abbreviations: CFU, colony-forming units; EF, edema factor ; LF, lethal factor; PA, protective antigen; SEM, standard error of the mean.
aMice were intranasally challenged with spores of the 9602WT-lux (EF+LF+PA+), 9602P-lux (EF+LF+PA-), 9602C-lux (EF-LF+PA+), 9602L-lux (EF+LF-PA+), or 9602LC (EF-LF-PA+) strain. The inoculum size was retrospectively verified by plating 10-fold serial dilutions on brain-heart infusion agar plates. Data are expressed as the mean ± SEM, with the number of experiments (n) shown in parentheses.
