The use of bioautography for quantitative measurement of gentamicin concentrations wzs compared with the disk test. Following chromatographic separation and bioautography, gentamicin produced inhibition zones, 2-7 times larger than the inhibition zones formed by the same amounts of gentamicin in the disk test. Bioautography, therefore, is a more sensitive assay method.
