What type of evidence supports the dressings’ effectiveness?

BIOGUARD® Barrier Dressings have been tested and have produced superior biocidal activity against a broad-spectrum of bacteria yielding a > 99.99% reduction of bacteria to the test site or a 5 log kill.

In a standard antimicrobial resistance assay, consistent exposure to PolyDADMAC – for a prolonged period of time– resulted in no resistance to the biocide treated substrate. Throughout a 10-round step-by-step adaptation training test, bacterial cells were exposed to PolyDADMAC. From each round only bacterial survivors were propagated into a new inoculum. Even after continued exposure to the biocide (10x), no resistance was formed.
