Ultraviolet Disinfection Effective Against Harmful Bacteria, Viruses and Fungi

The Microbiological Impact of Pulsed Xenon Ultraviolet Disinfection on Resistant Bacteria, Bacterial Spore and Fungi and Viruses

Published: South African Journal of Infectious Disease, May 2016


Studies have shown that at least a portion of hospital-acquired infections, a leading cause of mortality and morbidity, are attributable to the environment. Studies have also shown that traditional cleaning may be insufficient to effectively clean a patient room. This study evaluated the effectiveness of killing multiple organisms, including Ebola, Bacillus anthracis, and a variety of bacteria and fungi known to cause harm.


The study found significant reduction in pathogen counts after use of pulsed Xenon UV light at a distance of 1 meter, including Ebola, Bacillus anthracis, Klebsiella pneumoniae, E. coli, Aspergillus niger, and several viruses.
