Microplastics accumulate priority antibiotic-resistant pathogens: Evidence from the riverine plastisphere

Researchers placed microplastics in river water and found they accumulated more antibiotic-resistant bacteria than natural sand particles, including dangerous pathogens like E. coli and Klebsiella. Most of the bacteria isolated from the plastic surfaces were multi-drug resistant and carried virulence traits like biofilm formation. This suggests microplastics in waterways may act as rafts for spreading antibiotic resistance through the environment.

Survival of human pathogens bound to microplastics during transfer through the freshwater-marine continuum: from wastewater discharge to the beach

Researchers tracked survival of E. coli, E. faecalis, and P. aeruginosa colonizing polyethylene microplastics as particles were transferred through a series of mesocosms simulating downstream transport from wastewater effluent through freshwater, estuary, seawater, and beach sand. All three pathogens survived the full environmental transition sequence in the plastisphere, with higher bacterial concentrations on microplastics than on glass controls, though die-off rates did not differ by substrate, demonstrating microplastics' potential to extend pathogen persistence across environmental boundaries.
