ANTIMICROBIAL-ANTIBIOFILM COMPOSITIONS COMPRISING DISODIUM EDTA AND SODIUM CITRATE

摘要

Compositions comprising chelating agents, metal ion salts, gelling agents or a buffer, antimicrobials, antibiofilm agents and a pH adjuster or a buffer for the prevention and treatment of wound infections and food-borne diseases involving bacterial biofilms are disclosed. The anti-infective properties of a composition include reduction or killing of anaerobic/aerobic/facultative gram-negative and gram-positive wound infection associated bacteria occurring in polymicrobial biofilms. The composition may be in the form of lotion, cream, ointment, dressing, bandage, rinse, soak, gel, spray, or other suitable forms, including certain devices. Additionally, the invention offers an efficient method of delivering the formulated composition containing one or two chelating agents or chelating agents alone or in combination with a metal ion salt using either a nanoparticle or other efficient delivery systems.
