The data collected under GLP independent testing using a predefined concentration of cultivated ATCC referenced bacterial strains, demonstrated the antimicrobial properties of Cupron copper oxide impregnated countertops. Protocol number 1 tested the capacity of copper oxide infused

countertops to kill a number of cultivated pathogens (Table 2) under conditions prescribed by the US EPA for the in vitro testing of the antimicrobial efficacy of copper oxide particles suspended in a plastic matrix. The organisms tested selleck products constitute a broad representation of current HAI organisms, and with over a three log reduction (>99.9%) achieved within 2 hours of exposure the authors conclude that these copper oxide infused countertops can be an additional tool www.selleckchem.com/products/cobimetinib-gdc-0973-rg7420.html for bioburden reduction and potentially reducing the risk of HAI. Importantly, as demonstrated by using Protocol 2, simulating prolonged PI3K inhibitor review surface wear, the countertops continue to be highly efficacious even after 12 consecutive wet and dry wear and inoculation cycles (Table 3), simulating surface abrasion that occurs due to cleaning and use. Despite the erosion of the countertops’ surface, there was no reduction in biocidal efficacy. This is explained

by the distribution of the copper oxide particles throughout the matrix, on and within the surface (Figure 1), and the appearance of “new” particles on the surface as the countertop surface is eroded. This property of the countertops practically endows them with biocidal properties for the life of the product. Protocol 3 demonstrated that the countertops are efficacious to consecutive bacterial inoculations (Table 4) in the same exact spot, indicating

that the countertops selleck kinase inhibitor do not lose their biocidal efficacy following bacterial kill, but maintain this biocidal property continuously. Copper has a long history as an antimicrobial and preventative measure and metallic copper countertops have previously been approved for EPA public health claims [32]. Field trials of these countertops have demonstrated the reduction in bioburden in a variety of clinical settings [33–37] and a reduction in the risk of infections [38, 39]. Based on the data presented in this publication, Cupron Enhanced EOS Surfaces infused with copper have been approved for public health claims relating to their anti bacterial efficacy. Some of the approved health claims are a) “This surface continuously reduces bacterial* contamination achieving a 99.9% reduction within two hours of exposure.”; b) “This surface kills greater than 99.9% of Gram negative and Gram positive bacteria* within two hours of exposure.”; c) “This surface kills greater than 99.9% of bacteria* within two hours and continues to kill 99% of bacteria* even after repeated contamination.”; and d) “This surface helps inhibit the buildup and growth of bacteria* within two hours of exposure between routine cleaning and sanitizing steps”.
