摘要：
Compositions and methods to treat biofilms are disclosed based on the discovery of the role of the disaccharide trehalose in microbial biofilm development. In various embodiments to treat body-borne biofilms systemically and locally, the method includes administering trehalase, the enzyme which degrades trehalose, in combination with other saccharidases for an exposition time sufficient to adequately degrade the biofilm gel matrix at the site of the biofilm. The method also includes administering a combination of other enzymes such as proteolytic, fibrinolytic, and lipolytic enzymes to break down proteins and lipids present in the biofilm, and administering antimicrobials for the specific type(s) of infectious pathogen(s) underlying the biofilm. Additionally, methods are disclosed to address degradation of biofilms on medical device surfaces and biofilms present in industrial settings.
