Evidence Of Persistence Of Lyme Disease In Humans
Persistence of Lyme disease after antibiotic treatment has been demonstrated in both animals and humans. In 2011, Dr. Stricker and Lorraine Johnson published an article that listed over 25 studies demonstrating persistence in humans after two-to-four weeks of therapy.

Current laboratory tests widely used for Lyme disease rely on indirect measures of infection based on the immune system’s antibody response to B. burdorferi—the bacteria which causes Lyme disease. Antibody tests are highly insensitive and miss a whopping 43% of Lyme disease cases. In addition, these tests can only determine past exposure to the bacteria, not active infection. They also cannot determine whether the infection has been eradicated.
By relying only on these flawed tests, doctors may believe the patient has been cured. However, this is not always the case. Researchers conducting extensive tissue biopsies of animals, a technique too invasive for clinical practice, have demonstrated disease persistence.
As the chart below shows, persistence of the bacteria in humans after only short-term treatment has also been shown through tissue biopsies of the brain, liver, spleen, skin, eye, bladder, and lymph nodes in numerous published studies.
It’s time to lay to bed the notion that persistence has not been demonstrated in humans. It has–as evidenced by these 27 case studies. Many of these studies used biopsies of brain, bladder, synovial fluid, liver, lymph node, central spinal fluid, spleen or iris. Clearly, this type of invasive tissue sampling is not performed on humans unless it is ancillary to some other essential medical intervention. The remaining studies used tests that are not in commercial use.
The fact that we have demonstrated persistence in some many cases despite these limitations is significant. The problem with demonstrating persistence on a regular basis is the poor state of testing in Lyme disease. We need a commercially available test that is non-invasive to establish persistence on a regular basis to monitor the effects of on-going treatment.
