Tests conducted at Ohio State University’s Wexner Medical Center and the Henry M. Jackson Foundation for the Advancement of Military Medicine and its Diagnostics and Translational Research Center confirm that a new wound dressing that uses microcurrent technology is effective in disrupting bacterial biofilms including Pseudomonas aeruginosa, which often is found in chronic wound infections.
Procellera, a product developed by Vomaris Innovations, uses small amounts of electricity to mimic the body’s own physiologic electrical currents that are essential for skin repair and wound healing. Results of this study were published in PLoS ONE and the Journal of Wound Care.
“Bacterial biofilms can dramatically impede wound healing and penetrate deeper into a wound bed to further infect implanted devices," said Michael Nagel, president and CEO of Vomaris Innovations, in a press release published in BioSpace. “Because of their resistance to treatment, biofilms present a significant challenge in today’s healthcare environment.”
Mina Izadjoo, PhD, principal investigator for the study, added: “We’re very encouraged by the implications of these results for wound care, which showed that this electroceutical dressing was effective in inhibiting growth of both mono- and multi-species biofilms, including multi-drug resistant strains.”
