METHOD FOR PHOTODYNAMIC INACTIVATION OF Enterococcus faecalis BACTERIA (VERSIONS) Russian patent published in 2015 - IPC A61K36/38 A61L2/02 A61L9/18

Abstract RU 2550132 C1

FIELD: chemistry.

SUBSTANCE: method for photodynamic inactivation and inhibition of growth of Enterococcus faecalis bacteria, based on pretreatment of the bacteria with a hypericin-containing photosensitiser based on an alcoholic tincture of hypericum "Diahyperon" or "Hypericum tincture" and subsequent exposure of the obtained suspension to optical radiation of laser or LED sources with transmission maxima in the region corresponding to absorption spectrum maxima or maxima of the excitation spectrum of fluorescent components of the preparations with radiation energy density of 0.9-9.0 J/cm², under certain conditions.

EFFECT: method simplifies inactivation of Enterococcus faecalis bacteria.
