New study results showed that a wound dressing containing ionic silver is able to kill several strains of highly-resistant bacteria, commonly referred to as 'superbugs,' within 48 hours, according to a news release.
A sample of the silver-containing sodium carboxymethyl cellulose wound dressing was aseptically transferred to a simulated wound fluid containing A. baumannii, C. difficile, community-associated MRSA or ESBL-producing bacteria. Following incubation, total viable counts were performed on each test model at four, 24, 48, 72, and 96 hours and at seven days. All models were re-inoculated with a fresh challenge of the same bacteria at 72 hours.
The dressing killed ESBL-producing bacteria and A. baumannii quickly and consistently, with an approximate 100,000-fold reduction of all pathogens within 24 hours. The rate of kill for C. difficile was rapid, with an approximate 100,000-fold reduction of all bacteria after four hours. The wound dressing also was effective against CA-MRSA, with a 100-fold reduction in bacterial population within 48 hours and no bacteria detected by day seven.
