Chronic wounds complicated by infection pose significant clinical challenges, necessitating comprehensive treatment approaches. The widespread use of antibiotics has led to resistant microorganisms, complicating traditional therapies. This study aims to develop and evaluate modified alginate wound dressings with enhanced antimicrobial and regenerative properties. Alginate dressings were synthesized with silver nanoparticles, cefepime, and fibroblast growth factor-2 (FGF-2). The two-stage therapy involved an initial antibacterial dressing followed by a regenerative dressing. In vitro tests demonstrated high antibacterial activity, with maximum inhibition zones for P. aeruginosa (41.3 ± 0.4 mm) and S. aureus (36.6 ± 1.8 mm). In vivo studies on rats with purulent wounds showed significant healing progression in the experimental group. Histological analysis revealed complete re-epithelialization, thicker neoepithelium, dense collagen deposition, and minimal inflammation in treated wounds. These findings suggest that the modified alginate dressings significantly enhance the reparative process and are promising for treating chronic infected wounds in both veterinary and medical practices. |
