Laser interferometric and cultivation methods for measurement of colistin/ampicilin and saponin interactions with smooth and rough of Proteus mirabilis lipopolysaccharides and cells.

Abstract excerpt

Laser interferometry is commonly used in permeability studies of soluble substances. In this study a modification that allowed testing partially insoluble mixtures is presented. The modification relies on the measurement of diffusion from 1% agarose gel. As a model for this study, two Proteus mirabilis strains were used that differ in polysaccharide content: smooth P. mirabilis S1959 strain and its Re-type...
