Chronic Lyme Disease

The recent review paper: "Persistent Borrelia Infection in Chronic Lyme Disease: A Review of the Medical Literature", examines whether Borrelia burgdorferi, the bacterium that causes Lyme disease, can persist in the body after standard antibiotic treatment. The authors analyzed 56 animal and human studies and found substantial evidence that Borrelia can remain detectable long after therapy.

Animal studies (including mice, dogs, and primates) frequently showed persistent bacteria using methods such as PCR, culture, and xenodiagnosis. Human studies also reported ongoing detection of Borrelia or its genetic material following treatment.

The paper discusses possible survival mechanisms, including cyst-like forms, cell-wall-deficient variants, and biofilms, which may protect the bacteria from antibiotics. While some researchers argue that lingering symptoms are due to immune responses rather than active infection, the reviewed evidence challenges that view.

Overall, the authors conclude that persistent Borrelia infection is biologically plausible and should be considered in understanding chronic Lyme disease, highlighting the need for further research and improved treatment approaches.
