Abstract
Official abstract text for this publication.
A method for inactivating medically important Gram-positive bacteria including Methicillin-resistant Staphylococcus aureus (MRSA), Coagulase-Negative Staphylococcus (CONS), Streptococcus, Enterococcus and Clostridium species, comprising exposure to visible light, and in particular light within the wavelength range 400-500 nm.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for disinfecting air, contact surfaces, or materials by inactivating methicillin-resistant Staphylococcus aureus (MRSA) in the air, on the contact surfaces, or on the materials, said method comprising exposing the MRSA to visible light without using a photosensitiser, wherein the visible light for inactivating the MRSA consists of wavelengths in the range of 400-420 nm, and wherein the method is performed outside of a human body, the contact surfaces or the materials are non-living, and the air, contact surfaces or materials are not exposed to a disinfecting dose of light at a wavelength above 500 nm. 2. A method as claimed in claim 1 wherein the light consists of wavelength 405 nm.
