(A) Effect of selection time on RLU value in the AccuProbe M. tuberculosis complex assay with M. celatum. There were no statistically significant differences between the mean RLU values with solid or liquid medium for the different selection times. The RLU values from the solid medium suspension were significantly higher than those from the broth-grown suspension at all selection times (P < 0.05). Data are expressed as means plus SEM. The RLU cutoff is 30,000. (B) Effect of temperature on RLU value in the AccuProbe M. tuberculosis complex assay with M. celatum. The Mann-Whitney U test revealed significant differences between the mean RLU values with solid medium for 58°C versus 60 and 61°C, between 59°C versus 60 and 61°C, and 60°C versus 61°C (P < 0.05). The RLU values from the solid medium suspension were significantly higher than those from the broth-grown suspension at all selection temperatures (P < 0.05). Data are expressed as means plus SEM. The RLU cutoff is indicated by a horizontal line.
