R-pyocins as targeted antimicrobials against Pseudomonas aeruginosa.

R-pyocins, bacteriocin-like proteins produced by Pseudomonas aeruginosa, present a promising alternative to phage therapy and/or adjunct to currently used antimicrobials in treating bacterial infections due to their targeted specificity, lack of replication, and stability. This review explores the structural, mechanistic, and therapeutic aspects of R-pyocins, including their potential for chronic infection management, and discusses recent advances in delivery methods, paving the way for novel antimicrobial applications in clinical settings.
