Abstract

Biocompatible and non-toxic properties of chitosan make it a candidate with excellent application prospects in developing wound dressing conjugate compounds. Six different chitosan-based nanohybrid membranes were evaluated against multidrug-resistant bacterial isolates. Different combinations of chitosan, ciprofloxacin (CIP), biofunctionalized montmorillonite (MMT), and montmorillonite with sulfate chains (SMMT) were provided, and their antibacterial activity was assessed using the colony count method. Totally, 27 drug-resistant isolates, including 6x methicillin-resistant Staphylococcus aureus, 7 vancomycin-resistant Enterococcus faecalis, 4 Acinetobacter baumannii, and 10 Pseudomonas aeruginosa isolates were identified from burn wound infections. Chitosan and montmorillonite did not show significant antibacterial effect (p > 0.05), but chitosan/SMMT/CIP was the most effective nanocomposite (p < 0.01). Chitosan-based nanocomposites with ciprofloxacin could effectively reduce the susceptibility of drug-resistant bacterial isolates. Bacterial targeting using nanosystems provides an opportunity for effective antibiotic treatment by improving antibacterial efficacy.
