Disinfection of methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus faecium and Acinetobacter baumannii using Klaran WD array system

Hospital-associated infections (HAIs) are a major burden in healthcare systems. In this study, UVC LEDs emitting radiation from 260 to 270 nm were evaluated for effectiveness in reducing methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium and Acinetobacter b...

Sumario:Hospital-associated infections (HAIs) are a major burden in healthcare systems. In this study, UVC LEDs emitting radiation from 260 to 270 nm were evaluated for effectiveness in reducing methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium and Acinetobacter baumannii . The array has four WD LEDs, each with 70 mW placed at 7 cm from test organisms. With 11.76 mJ cm(−2), the study obtained 99.99% reduction (log(10) reduction factor of 4) against MRSA and VRE. For A. baumannii , 9 mJ cm(−2) obtained 99.999% reduction (log(10) reduction factor of 5). These results present scientific evidence on how effective UVC LEDs can be used in the fight against HAIs.
