Science Translational Medicine Study Funded by the Bay Area Lyme Foundation Identifies FDA-approved Piperacillin as More Effective, Targeted Treatment for Lyme Disease
An additional Science Translational Medicine study also funded by Bay Area Lyme Foundation uncovers how lingering bacterial cell wall molecules may contribute to chronic Lyme symptoms
PORTOLA VALLEY, Calif. April 23, 2025 – Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, announces two pre-clinical studies published in the peer-reviewed journal Science Translational Medicine. The studies demonstrate promising implications for improved Lyme disease treatment and understanding of chronic Lyme through peptidoglycan, a molecule found in the cell wall of the bacterium, Borrelia burgdorferi (Bb), which causes Lyme disease. The first study finds piperacillin, an FDA-approved treatment for pneumonia that inhibits peptidoglycan production, may be a more effective treatment for Lyme disease than the current “gold standard” treatment, doxycycline, which is not effective for up to 20% of patients. The second study uncovers how lingering peptidoglycan builds up in the joint fluid and liver, contributing to chronic Lyme symptoms, which affect over 20% of patients treated for Lyme disease.
“Piperacillin may be a game-changer for improving Lyme disease treatment, which is currently a challenge for researchers and physicians. Furthermore, our new mechanistic understanding of how piperacillin affects peptidoglycan synthesis is unexpectedly informing our development of a biomarker-based approach to diagnose acute Lyme disease,” said Brandon Jutras, PhD, associate professor of Microbiology-Immunology at Northwestern University Feinberg School of Medicine, and a Bay Area Lyme Foundation 2021 Emerging Leader Award winner. “Our second study explores the role of peptidoglycan in chronic Lyme symptoms; peptidoglycan influences an inflammatory and chronic illness response for weeks or even months after infection, adding to the growing evidence that remnants of bacteria and viruses can stick around and keep affecting the body, similar to the occurrence of Long COVID in some patients.”
