N2 - Given the rise of multidrug-resistant (MDR) Pseudomonas aeruginosa infections, alternative treatments are needed. Anti-pseudomonal phage therapy shows promise, but its clinical application is limited due to the development of resistance and a lack of biofilm penetration. Recently, adjuvants like CaEDTA have shown the ability to enhance the effectiveness of combined antimicrobial agents. Here, we tested a phage-adjuvant combination and demonstrated the effectiveness of intranasally inhaled phage (KKP10) + CaEDTA in addition to ceftazidime/avibactam (CZA) for chronic P. aeruginosa lung infections. The results emphasize that intranasal inhalation of phage along with CaEDTA can successfully re-sensitize MDR P. aeruginosa to CZA in a triple combination treatment. This promising approach shows potential as a therapy for chronic respiratory tract infections.
