The present invention relates to methods for treating microbial infections on the surfaces of an implant or other surfaces near an implant in a patient. In particular, the methods are useful for treating biofilm infections. The methods include the use of minimally invasive techniques, including the use of ultra sound for facilitating the detection of biofilm infections on the implant or other surface of a patient and destroying the infection by administering an anthocyanin or an anthocyanidin or metabolite thereof. In particular, the administration of protocatechuic acid (PCA) or 2,4,6 trihydroxybenzaldehyde (2,4,6 THBA) for the treatment of an infected implant or other surface of a patient is described herein.

The present invention is directed to a composition in solution (often, an aqueous solution) which comprises a combination of molecular iodine (I.sub.2) and an acceptable source of iodate (IO.sub.3), and an acid (inorganic or organic), wherein iodide and iodate are present in the composition at a molar ratio of about 0.1 to about 25, the concentration of uncomplexed molecular iodine is a disinfectant, biocidal and/or antimicrobial (depending upon the end use of the composition) effective amount the concentration of acid in the composition is effective to provide a buffering pH in the composition ranging from about 1.5 to about 6.5. Compositions according to the present invention are storage stable for unexpectedly long periods of time (up to about 5 years), and find use as disinfecting solutions, as germicides and/or biocides (e.g. antiviral, antibacterial, antifungal, antispore etc.) for various surfaces and solutions including living and inanimate surfaces and are particularly useful because of their low cost, their reduced use of iodine, their activity (because of the high concentration of free molecular iodine in solution), their reduced environmental impact, their long term storage stability and their reduced toxicity. They also have particular utility in treating food surfaces to retard spoilage, increase useful shelf-life and minimize the human and economic cost of food waste. The compositions inactivate viruses, bacteria (both gram negative and positive), spores and fungi. Compositions according to the present invention may be used and stored in a variety of materials, given the substantial absence of corrosion (non-corrosive) these compositions display. Dental compositions (e.g. preprocedure rinses and other compositions) and methods related thereto are also disclosed.

In the present disclosure, a temperature-sensitive inner layer solution, a deformation intermediate layer solution, and a rigid outer layer solution are first prepared and spray-coated layer by layer on a surface of a fruit or vegetable, such that three preservative film layers are produced successively and can be used for the preservation of the fruit or vegetable.

This disclosure provides generally for antimicrobial compositions and methods of use comprising an anthocyanin, an anthocyanidin or metabolites thereof. Methods for promoting healing of a wound using these compositions are also disclosed. These compositions have broad spectrum antimicrobial activity and are safe for human and animal uses. Further, these compositions are safe for medical uses and industrial uses as antiseptic preparations to reduce or prevent microbial growth, including killing bacterial biofilms.
