13C18O dose curve. M. bovis BCG (3 ml, 1 × 107 CFU/ml) was incubated with 13C18O gas for 22 h. Headspace gas was analyzed by isotope ratio mass spectrometry (IRMS) to determine Δ47. Data represent means ± SD (n = 4) of results from separate biological replicates. By one-way ANOVA with the Tukey test as a post hoc test (ANOVA between groups), P was <0.001 (*) versus results with a 0-ml CO dose.
