The efficacy of subcutaneously administered polymyxins against burn wound infections caused by Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae was examined in a murine infection model. Subcutaneously administered colistin and polymyxin B (30 mg/kg thrice daily) achieved a ≥2-log10 reduction in the bacterial load for P. aeruginosa and A. baumannii infections, whereas wound infections by K. pneumoniae were less responsive (<1-log10 reduction). This study highlights the potential therapeutic benefits of parenteral polymyxins for treating burn wound infections.
