[Rapid determination of the minimal inhibitory concentration of an antibiotic by measuring bacterial ATP (author's transl)].

The minimal inhibitory concentrations (MIC) of gentamicin for ten strains of Enterobacteriaceae were determined by measuring the bacterial ATP (adenosine triphosphate). ATP was measured by chemiluminescence on 4-h growth cultures which included gentamicin. The MIC results obtained by this method were equivalent to those found with the technique of dilution in liquid medium.
