Hydrogel dressing containing natural extracts inhibits dual-species biofilms of Staphylococcus aureus and Acinetobacter baumannii in ex vivo wound infection models

open access: yesScientific Reports
Wound infections represent a significant cause of delayed wound healing. An active wound dressing was developed by incorporating extracts of Rhodomyrtus tomentosa leaf and Quercus infectoria gall in a carboxymethyl cellulose hydrogel (RQ hydrogel).
