“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.

FOR IMMEDIATE RELEASE

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.

UCSF’s New Lyme Clinical Trials Center: Addressing the Need for Evidence-Based Treatments for Lyme & TBD Patients

Bay Area Lyme Happenings Series

UCSF has joined the Cohen Foundation’s nationwide Lyme Clinical Trials Network (CTN) for Lyme and tick-borne diseases. The new Lyme Clinical Trials Center (CTC) at UCSF was funded by a $1m grant from Bay Area Lyme Foundation and is led by Charles Chiu, MD, PhD, and Felicia Chow, MD, as co-principal investigators. As the West Coast ‘node’ in the network, UCSF’s new Lyme Clinical Trials Center will focus on interventional trials and diagnostic studies to improve diagnosis and treatment of Lyme disease.

In this presentation to patients with Lyme disease in Marin County just north of San Francisco, Dr. Chow explains how the CTC allows for a more diverse patient population to participate in Lyme clinical trials, which is critical for developing therapies that can help a wider range of patients. UCSF’s involvement also aims to help Bay Area Lyme raise awareness that Lyme disease is prevalent year-round in almost all California counties.

Dr. Chow discusses an upcoming trial at UCSF that will evaluate the use of transcranial direct current stimulation (tDCS) to improve cognitive symptoms in patients with chronic Lyme disease. Additionally, UCSF researchers are exploring the use of metagenomic sequencing and machine learning to develop more accurate diagnostic tests for Lyme and other tick-borne infections.

Note: This transcript of Dr. Chow’s presentation has been edited for length and clarity.

“I hope that through these clinical trials, we’ll be able to identify therapies that are helpful to patients and that, as a result, have an impact on clinically meaningful outcomes—from day-to-day function, quality of life, and all of those important measures that indicate that a treatment is successful.”
