| Abstract: | The applicability of indirect conductimetric assays for evaluation of antibacterial activity was examined. The minimal inhibitory
concentration (MIC) obtained by the indirect method was consistent with that by the direct conductimetric assay and the turbidity
method. The indirect assay allows use of growth media, which cannot be used in the direct conductimetric assay, making it
possible to evaluate the antibacterial activity of insoluble or slightly soluble materials with high turbidity, such as antibacterial
ceramic powders.
