The Pathogen Reduction Box (PRB) using Far-UV Sterilray technology was tested in a clinical setting for its effectiveness against MRSA, VRE, and C. difficile spores.
The largest reduction in the smallest amount of time was Clean HA MRSA at 5 seconds of FAR-UV+ exposure with kills of 4 log.
Complete HA MRSA eradication was accomplished in the trials.
The same activity occurred against multiple strains of MRSA, to be specific, the community-associated 300 stain type and ATCC strain 43300.
“The PRB would be practical to use in the eradication of MRSA from small hospital surfaces.”
• 20 Remote controls on the ward were disinfected using the PRB for 60 seconds without adjusting the positioning of the remote control in the PRB.
• 20 Remote controls were sampled for MRSA, VRE, C.diff, and total bacteria before and after PRB treatment.
The data shows a 10 fold reduction of bacteria in patient rooms on remote control surfaces.
This correlates to a greater than 1.5 log reduction or a 98% reduction in aerobic bacteria; limited only by the amount of bacteria on the controls.
Lab studies show that the PRB is capable of reducing 4 logs of MRSA or more.
