The expression of toxR in wild type under different conditions using a P _toxR -luxCDABE transcriptional reporter. (A). The reporter strain was grown at 22°C or 37°C, and at successive time points, luminescence was measured. Units are arbitrary light units/OD₆₀₀. The results are the average of three experiments ± SD. (B). The reporter strain was grown at 37°C aerobically, in an anaerobic chamber (Mini MACS Anaerobic workstation, Microbiology International) or in a BBL CampyPak Microaerophilic System. At different time points, samples were withdrawn and luminescence was measured. Units are arbitrary light units/OD₆₀₀. The results are the average of three experiments ± SD.
