Robot Proven To Kill Superbug
A new study claims a pulsed ultraviolet disinfecting technology can destroy the superbug Candida auris, according to a statement from the product's manufacturer, Xenex.
Candida auris (C.auris) is an emerging, often multi-drug resistant, fungus that causes serious and often deadly infections in healthcare settings. The Centers for Disease Control and Prevention (CDC) recently issued a warning about C.auris, terming it a "serious global health threat."
Nearly 700 C.auris cases have been reported in the U.S. thus far, but hospitals overseas have been battling the deadly pathogen for quite some time. The Netcare Hospital Group, which operates the largest private hospital network in South Africa, was the first and is the only hospital group in South Africa to utilize Xenex high intensity, broad spectrum mobile disinfection robots that have been proven effective against viruses and bacteria that can threaten patient safety. Dr. Caroline Maslo is senior clinical advisor and head of infection control for Netcare's Hospital Division, and the lead author of a new peer-reviewed study "The efficacy of pulsed-xenon ultraviolet light technology on Candida auris" that validates the efficacy of LightStrike pulsed xenon ultraviolet (UV) disinfection technology in destroying C.auris.
In the BMC Infectious Diseases study, researchers reported a 99.6 percent reduction in C.auris after a 10-minute treatment with pulsed xenon UV disinfection.
"As an evidence based company, seeing this research documenting the efficacy of pulsed xenon UV disinfection technology against C.auris is very exciting," says Dr. Mark Stibich, co-founder and chief scientific officer at Xenex. "We began hearing reports of C.auris some time ago and began testing in government laboratories to create protocols for how our technology should be utilized to combat it. This data from Dr. Maslo's group further validates our best practices."
Xenex LightStrike robots quickly destroy bacteria, viruses, mold, fungus and spores on hospital surfaces. The portable disinfection robots are effective against the most common as well as the most dangerous pathogens, including Clostridium difficile (C. diff), norovirus, influenza, Ebola, carbapenem-resistant Enterobacteriaceae (CRE), Vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA). Trained hospital cleaning teams operate the robot, which is brought in after the patient has left the room as part of a hospital's comprehensive infection prevention strategy. The intense pulsed xenon UV light quickly destroys invisible pathogens lurking on surfaces (bedrails, tray tables, door knobs, wheelchairs, etc.).
LightStrike robots have been studied extensively in the hospital environment and credited in numerous peer-reviewed, published studies with helping hospitals decrease their C.diff, MRSA and Surgical Site Infection (SSI) rates from 46 percent to 100 percent.
