Activity of antimicrobial compounds against diverse T. foetus and T. vaginalis strains.

T. foetus and T. vaginalis cultures were incubated for 24 hours with a range of drug concentrations, ATP content was assayed as a measure of cell growth and viability, and pIC50 values were calculated from the resulting concentration-response curves. Data are shown as mean ± SE of three or more independent experiments. IC50 values were derived from the mean pIC50. The highest tested drug concentration was 20 μM, so lack of growth inhibition at that concentration is listed as IC50 >20 μM.
