New Peer-Reviewed Publication Highlights Evidence of Mother-to-Child-Transmission of Lyme Disease Bacteria During Pregnancy and Calls for Urgent Research

New paper in Frontiers in Medicine reports results of meeting of international researchers at the Banbury Center of Cold Spring Harbor Laboratory

PORTOLA VALLEY, Calif., April 9, 2026 –Bay Area Lyme Foundation, a national nonprofit and leading sponsor of tick-borne disease research in the US, today announced publication of a new peer-reviewed article in Frontiers in Medicine examining the transmission of the Lyme bacteria during pregnancy. The publication points to observational research demonstrating that Lyme bacteria are capable of being transmitted from mother to unborn child and recognition by both the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) of the potential for mother-to-child transmission. With approximately 500,000 Americans diagnosed with Lyme disease each year and the related correlation of transmission during pregnancy being associated with serious adverse pregnancy outcomes, such as miscarriage, stillbirth, or congenital infection that occur in some cases, the paper concludes that the clinical impact of Lyme disease on pregnancy and infant health is an important public health issue that has been insufficiently studied.

“As an infectious disease pediatrician, I have seen firsthand the impact of Lyme disease in children and have suspected that the infection may have been passed from mother to child during pregnancy in a number of my patients, based on their medical histories,” said Charlotte Mao, MD, of Bay Area Lyme Foundation and a co-author of the study. “The first case studies of mother-to-child transmission were observed in the 1980s, yet decades later, we still lack sufficient research and clear, evidence-based guidance on Lyme in pregnancy and adverse pregnancy outcomes. This is an important public health issue and underscores the urgent need for rigorous studies to fully understand the risks and support patients and healthcare providers in making informed decisions that better protect maternal and infant health.”

Study authors highlight the great need for real-world studies clarifying how Lyme Borrelia, the bacteria that cause Lyme disease, the most common vector-borne disease in the US, behaves during pregnancy, and quantifying the outcomes for mothers and infants. Specifically, the paper suggests the creation of large, prospective studies of pregnant individuals with Lyme disease, including systematic long-term clinical follow-up of their children, as well as the importance of collecting biological samples from mothers, placentas, and infants through coordinated biorespositories for use in current or future studies.

Improving Lyme Diagnostics, Biomarkers, and Treatment: Inside Dr. Peter Gwynne’s Research

“I wanted to be doing work that was driven by clinical need… and there are a lot of clinical needs in Lyme disease.”

– Peter Gwynne, PhD

For too many people with Lyme disease, the journey begins with uncertainty. A missed rash. A negative test. Symptoms that don’t make sense. A diagnosis that comes too late, or not at all. Bay Area Lyme Foundation believes this must change. And we believe change happens through funding rigorous science, innovative thinking, and supporting researchers willing to tackle the hardest questions head-on.

One of those scientists is Tufts researcher Peter Gwynne, PhD, a microbiologist whose work sits at the cutting edge of Lyme research and is the recipient of our 2022 Emerging Leader Award. We spoke with Dr. Gwynne to get an inside look at his work and understand how this may impact Lyme patients in the future. His focus is simple to state but complex to achieve: develop better diagnostics, identify meaningful biomarkers, and move the field toward treatments and even prevention strategies that could fundamentally reshape how Lyme disease is understood and managed.

Drawn to Lyme by the Urgency of the Need

Dr. Gwynne did not begin his career in Lyme disease. He trained in molecular microbiology, studying pathogens such as Salmonella and Staphylococcus, the bacteria responsible for serious infections, including those often acquired in hospital settings. But over time, he found himself seeking work that could make a tangible difference for patients.

“Chronic Lyme Disease patients have been ignored for too long. That must end now.”

– Charlotte Mao, MD, MPH

A Long-Overdue Moment of Recognition

Starting in 2026, Lyme disease and other tick-borne disease patients and their families have some reason to be encouraged by the growing recognition of the realities they face and the prospect of continued research to support new diagnostics and treatments.

The December 15, 2025, Department of Health and Human Services (HHS) roundtable marked something rare and long overdue: federal recognition of patient need, grounded in scientific evidence presented by researchers, clinicians, and patient advocates. But patients need more than another moment of recognition. They need results. In 2026, the question is whether that recognition will translate into sustained action, measurable progress, and real improvements in care.

Journal of Clinical Microbiology Studies Demonstrate Two Investigational Diagnostics Outperform Current Tests in Detecting Early Lyme Disease

Studies utilize Bay Area Lyme Foundation’s Lyme Disease Biobank samples to point to the promise of single-tier diagnostics to potentially transform early detection

PORTOLA VALLEY, Calif., October 9, 2025 — Bay Area Lyme Foundation, the leading nonprofit funder of Lyme disease research in the US, today announced results from two independent studies published in Journal of Clinical Microbiology, conducted by researchers at Tufts University School of Medicine, and Kephera Diagnostics, respectively, demonstrating the potential of novel investigational single-tier Lyme disease tests to improve accuracy in the earliest stages of infection. Each study uses well-characterized samples from Bay Area Lyme Foundation’s Lyme Disease Biobank and demonstrated unprecedented accuracy, far exceeding the current CDC-recommended Lyme disease two-tier test, which can miss up to 70% of early-stage cases as well as later-stage cases.

“The CDC’s standard two-tier Lyme diagnostic misses the majority of early cases, delaying treatment and increasing the risk of developing persistent, debilitating symptoms for patients. The two novel single-tier assays—while not yet FDA-cleared for clinical use—point to a future where Lyme disease can be diagnosed quickly, accurately, and with a single test,” Liz Horn, PhD, MBI, a coauthor on both studies, and Principal Investigator of Lyme Disease Biobank, a Bay Area Lyme Foundation program that provides much-needed samples to approved researchers working to better understand tick-borne diseases and develop improved diagnostic tests and therapeutics. “These single tier tests, like InBios Lyme Detect™ and Kephera’s Hybrid Lyme ELISA could mark a turning point for Lyme diagnostics, giving physicians and patients more accurate tools that are urgently needed.”

The first study, evaluating the InBios Lyme Detect™ Multiplex ELISA, was conducted by Pete Gwynne, PhD, a 2022 Bay Area Lyme Emerging Leader Award (ELA) winner, and colleagues at Tufts University School of Medicine. Using samples from the Lyme Disease Biobank, this new diagnostic correctly identified all two-tier positive samples evaluated in the study, while also detecting 21 of 79 clinically diagnosed patients who were missed by following the current CDC guidance for testing using FDA-cleared standard two-tier tests (STTT) and had erythema migrans (EM) skin lesions. Importantly, the InBios test maintained >99% specificity, with only one false positive across more than 200 control and lookalike disease samples and was shown to be highly reproducible.

Bay Area Lyme Foundation Announces National Winner of the 2025 Emerging Leader Award to Develop a Much-Needed Rapid, Low-Cost, Easy-to-Use Lyme Disease Test

Winner Chao Wang of Arizona State University will receive $150,000 to evaluate a unique diagnostic that uses gold nanoparticles and has been proven in other infectious diseases

PORTOLA VALLEY, Calif., June 12, 2025—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, has given its 2025 Emerging Leader Award (ELA) to Chao Wang, PhD, associate professor in the School of Electrical, Computer and Energy Engineering at Arizona State University, faculty with ASU’s Biodesign Institute® and an expert in nanotechnology and biosensors. Wang will receive $150,000 to support his work to develop a much-needed rapid, low-cost, easy-to-use test, called Nano2RED-LD, for Lyme disease. The test aims to deliver results in as few as 30 minutes when a patient who may have Lyme disease first sees a doctor.

There is an immense need for better Lyme disease tests. Today’s standard-of-care tests miss too many cases at all stages of Lyme disease, including as many as 70% of early Lyme cases.

“With Lyme disease cases rising steadily across the U.S., the need for accurate and timely diagnostic tools has never been greater,” said Katariina Tuovinen, research grant director, Bay Area Lyme Foundation. “Dr. Wang’s pioneering work epitomizes the essence of this award as it applies innovation from other infectious diseases in an effort to enhance outcomes for patients affected by Lyme disease.”

Science Translational Medicine Study Funded by the Bay Area Lyme Foundation Identifies FDA-approved Piperacillin as More Effective, Targeted Treatment for Lyme Disease

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.”

“I’ve always said that the FDA has been captured by the pharmaceutical industry. They don’t have our best interests at heart. You shouldn’t be funded by the people you’re supposed to be regulating.”

– Steven Phillips, MD

Ticktective host, Dana Parish, talks with her longtime collaborator and co-author of Chronic, Dr. Steven Phillips, a Yale-trained internal medicine doctor who specializes in treating patients with complex, chronic illnesses, often driven by underlying infections like Lyme, Bartonella, Babesia, and now, COVID. In this podcast episode, Phillips discusses the importance of getting to the root cause of mystery autoimmune illnesses, rather than just suppressing symptoms. He states that many chronic infections can drive autoimmune conditions, including Lyme disease, and that Lyme tests are often inaccurate, with a sensitivity of around 50%. Phillips discusses how he recommends treating suspected tick bites to prevent the development of chronic Lyme disease and his use of a multi-antibiotic approach and pulsed antibiotic therapy to target persistent infections. He also discusses his experiences treating COVID-19, using a multi-modal approach including doxycycline, Paxlovid, Metformin, and other drugs and supplements, and the reactivation of infections like Bartonella in Long COVID patients. They also discuss how the chemical and pharmaceutical industries’ interests do not necessarily align with patients trying to get well. The interview highlights Dr. Phillips’s expertise in treating complex chronic infections and his holistic, evidence-based approach to patient care.
