ABSTRACT
OBJECTIVE: Bacterial wound infections have recently become a threat to public health. The emergence of multidrug-resistant (MDR) strains of Klebsiella pneumoniae highlights the need for a new treatment method. The effectiveness of bacteriophages has been observed for several infections in animal models and human trials. In this study, we assessed the effectiveness of bacteriophages in the treatment of wound infections associated with MDR and biofilm-producing K. pneumoniae and compared its effectiveness with that of gentamicin. METHODS: A lytic phage against MDR K. pneumoniae was isolated and identified. The effectiveness of phages in the treatment of wound infection in mice was investigated and its effectiveness was compared with gentamicin. RESULTS: The results showed that the isolated phage belonged to the Drexlerviridae family. This phage acts like gentamicin and effectively eliminates bacteria from wounds. In addition, mice in the phage therapy group were in better physical condition. CONCLUSION: Our results demonstrated the success of phage therapy in the treatment of mice wounds infected with K. pneumoniae. These results indicate the feasibility of topical phage therapy for the safe treatment of wound infections.
