Abstract: Metal-associated infections such as prosthetic joint infection (PJI) cause significant morbidity across the world. Infected implants frequently require surgical removal and weeks of antibiotics. This is in large part due to the formation of biofilm. Embodiments described herein utilize alternating magnetic fields (AMF) as a non-invasive approach for eradicating (i.e., significantly reducing) biofilm off of metal. Embodiments apply brief intermittent bursts of AMF given in concert with traditional antibiotics to synergistically remove biofilm off of metal. This effect is seen across common PJI-associated pathogens and with clinically used antibiotics. Utilizing AMF in an intermittent fashion has important implications for providing a non-invasive treatment that could be both safe and effective in patients.
