    ECMO is a critical life support system for severe cardiac and pulmonary failure, with significant risks for nosocomial infections.

  • 2

    Biofilms on ECMO cannulas can act as reservoirs for secondary infections and antibiotic resistance, complicating patient outcomes.

  • 3

    This study utilized 16S rDNA amplicon sequencing to analyze microbial communities on ECMO cannulas, skin, and blood samples.

  • 4

    Contradictory findings exist regarding the impact of biofilms on patient outcomes, highlighting a gap in understanding their clinical significance.

  • 5

    The study aimed to identify bacterial sources on cannulas and assess the risk of secondary infections post-decannulation.
