Summary

This review examines how marine microplastics serve as surfaces for biofilm formation by bacteria, including carbapenem-resistant strains, enabling the global dissemination of antimicrobial-resistant bacteria through ocean currents. The authors highlight the plastisphere as an understudied vector for spreading antibiotic resistance genes across marine environments.

Microplastics (MPs) are globally anthropogenic contaminants of marine environments. Bacteria can colonize MPs forming biofilms that constitute the plastisphere. Carbapenem-resistant bacteria in plastisphere could be a hidden threat for marine life. The role of MPs in the spread of AMR bacteria/genes deserves global investigation.
