Researchers from the Brunel University of London have found, per a new study in the [journal *Cell*](), that the bacterial *Pseudomonas aeruginosa* appears to "digest" medical plastic. Associated with more than [559,000 deaths globally]() per year, this drug-resistant bug is, according [to the Center for Disease Control and Prevention](), believed to cause other illnesses like pneumonia or urinary tract infections. People often seem to develop it after surgery, but until this study, researchers weren't aware that it might be living or feeding on medical plastics. By analyzing a strain of the bacteria taken from a patient's wound swab, the microbial researchers found that *P. aeruginosa* seems specifically to survive longer on polycaprolactone, a plastic used in all kinds of medical interventions ranging from sutures, stints, and surgical mesh to wound dressings, drug-delivery patches, and implants. In Brunel University's press release about the "[world-first]()" research, study leader Ronan McCarthy said this finding suggests that medical professionals should rethink how bugs spread throughout hospitals and other healthcare settings. "Plastics, including plastic surfaces, could potentially be food for these bacteria," McCarthy said. "Pathogens with this ability could survive for longer in the hospital environment." The study also, as the professor noted, "means that any medical device or treatment that contains plastic" — including the ventilators some pneumonia patients need and catheters necessary for UTIs — "could be susceptible to degradation by bacteria." Beyond its ability to break down such important medical tools, the researchers also found that the enzyme they isolated appears to grow stronger biofilms, or outer layers that help bacteria resist antibiotics and make them harder to treat, after digesting plastic. Though there will obviously need to be more study to figure out how best to head off this plastic-eating menace, there's a [200-year history]() of pathogenic adaptation behind *P. aeruginosa* that suggests it may eventually circumvent any such measures. Still, McCarthy pointed out that scientists "need to understand the impact this has on patient safety." "Plastic is everywhere in modern medicine," he said, "and it turns out some pathogens have adapted to degrade it." **More on bacteria**: [*Mysterious Bacteria Not Found on Earth Are Growing on China’s Space Station*]() ## Author At Futurism, I've often been drawn to unpacking the narratives that underlie technological, scientific and medical progress, with a special interest in areas of conflict and ambiguity that end up setting agendas and steering the fates of both elites and the hoi polloi. I'm a committed generalist, but I often find myself returning to work involving NASA and the private space sector, the effects of AI on media and society, and the mechanics of the pharmaceutical industry, with a specific focus on the spread of GLP-1 drugs like Ozempic and Wegovy. Prior to Futurism, I worked for publications ranging from Media Matters and Truthdig to Raw Story and Bustle. I'm also the author of "Myspace Scene Queens," a 2024 title in Instar Books' acclaimed "Remember the Internet" series. My work at Futurism has been cited by outlets including the New Yorker, Slate, Nieman Lab, the Verge, the MIT Technology Review, the Sunday Times, and the Daily Beast. I grew up in North Carolina, attended the University of North Carolina at Asheville, and now live in Brooklyn, New York. In my free time, I'm an avid reader and music fan; you can probably find me at a local poetry reading, concert, underground rave, or DJ set. I'm the proud parent of an ineffable orange cat named Mee-Mow. ### Author social links [Bluesky]()
