(-)-Terpinen-4-ol in combination with erythromycin reduces ATP levels in MDR K. pneumoniae. K. pneumoniae BC1415 was exposed to (-)-Terpinen-4-ol during 6 h. The ATP levels were quantified using a luciferin-luciferase bioluminescence detection assay. CCCP (2 µg/mL) was included for comparison. The results presented correspond to the mean of three independent readings ± SD. Results were considered highly significant where ***P < 0.001.
