Penetration of dioxidine to the cells of Staphylococcus aureus and the drug effect on subcellular fractions were examined. High pressure liquid chromatography demonstrated that after penetration to the cells of Staphylococcus aureus dioxidine was found unchanged in the cytoplasmic fraction. Differences were disclosed in the biochemical action pattern of the drug on the growing and stationary culture. Exposure of the growing culture to dioxidine resulted in an appreciable decrease in the protein and especially in nucleic acid levels, in significant changes in the composition of the intracellular protein complex. The drug produced structural alterations within the cell wall. These alterations increased with concentrations and were characterized by the loosening of the wall and by the membrane release.

UI MeSH Term Description Entries
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
