  • Patent number: 9255251
    Abstract: A method of preparation of purified bacteriophage with increased antibacterial activity, in which from bacterial lysate of phages is obtained, advantageously in the presence of lysozyme, chelating factor and detergent, in a continuous manner with ultrafiltration on membranes, the phage containing high molecular mass preparation, devoid of bacterial cell wall and other contaminants, free of toxins and endotoxins, active in tests of bacterial lysis, which is characterized by chromatography HPLC, In SDS-PAGE electrophoresis, immunoblotting, biological tests of bacterial lysis, and is dedicated for phage therapy of bacterial infections and tumors and for production of phage deriving pharmaceutical preparations.
    Type: Grant
    Filed: February 8, 2008
    Date of Patent: February 9, 2016

  • Patent number: 9238798
    Abstract: The subject the present invention is a method of producing a pharmacologically stable form of purified and lyophilised bacteriophage preparations of increased stability and antibacterial activity, characterized in that phages produced from a bacterial lysate, for example by ultrafiltration on ultrafiltration membranes, containing a high molecular weight preparation of purified phages is stabilised most preferably with a probiotic extract in the presence or absence of neutral salts and/or organic solvents, lyophilised, characterised via HPLC chromatography, by SDS-PAGE, and bacterial lysis biological assays, and then stored under a vacuum, where the active lyophilisate is destined for phage therapy of infections and tumors.
