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

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

Combination Antibiotic Therapies May Be Capable of Eradicating Lyme Disease, According to Investigational Study Funded by Bay Area Lyme Foundation

Study identifies persistent Lyme bacteria in tissue samples and points to need for clinical studies of combination antibiotics in persistent Lyme

PORTOLA VALLEY, Calif., November 21, 2023—Bay Area Lyme Foundation, a leading public foundation sponsor of Lyme disease research in the US, today announced results of a laboratory study published in the peer-reviewed journal Frontiers in Microbiology that identifies seven combination therapies that are superior to courses of single antibiotics for treating persistent Lyme disease in an investigational model. These combination therapies were able to eradicate the bacteria from tissue samples, and the study was conducted by Bay Area Lyme Foundation Scientific Advisory Board member Monica Embers Ph.D., along with other researchers from Tulane University.

“Our results support the experience of Lyme disease patients whose symptoms have not resolved after a standard course of antibiotics, and these new data suggest that combination therapy should be investigated in clinical studies for treating persistent human Lyme disease,” said Embers, an associate professor of microbiology and immunology and director of Vector-borne Disease Research at Tulane National Primate Research Center.

While none of the single courses of antibiotics eliminated persistent infection in this investigational study, some combinations of already FDA-approved antimicrobial treatments were able to eradicate the bacteria. Specifically, four different dual combinations of antibiotics (doxycycline and ceftriaxone; dapsone and rifampicin; dapsone and clofazimine; doxycycline and cefotaxime) and three triple combinations of antibiotics and antimicrobials (doxycycline, ceftriaxone and carbomycin; doxycycline, cefotaxime and loratadine; dapsone, rifampicin and clofazimine) eradicated persistent infections of Borrelia burgdorferi, the bacteria that causes Lyme disease.
