Silent transmission of clonal Pseudomonas aeruginosa via duodenoscopes: microbiological and genomic investigation of a prolonged episode
This study demonstrates that clonal P. aeruginosa contamination of duodenoscopes can persist undetected despite routine testing and strict reprocessing. Infections may arise outside typical outbreak settings and involve non-MDRO strains. Enhanced detection strategies, improved endoscope designs, and broader post-procedural surveillance are needed to prevent such silent transmission.
