Novel techniques for determination of antibacterial activity of silver sulfanilamides.

By means of suspension techniques, MIC's of ten silver sulfanilamides against fifty-six different strains of bacteria were determined. The only two bacteria which were sensitive were Streptococcus pyogenes and Escherichia coli. The local application of these drugs in burn patients only reduces colonization. The cream base is probably also involved in the anticolonization effect.
