Summary

Researchers showed through microcosm experiments that PFOA, a common PFAS compound, selects for antibiotic-resistant bacteria and increases transcription of antimicrobial resistance genes, suggesting that environmental PFAS contamination may contribute to the spread of antibiotic resistance.

Study Type In vitro

In vitro microcosm experiments showed that PFOA (perfluorooctanoic acid) selects for antibiotic-resistant bacteria, characterized by WGS, which displayed increased transcription of AMR genes during growth in the presence of PFOA.
