Clinical Information

Borrelia miyamotoi is a spirochetal bacterium that is closely related to the Borrelia species that cause tick-borne relapsing fever (TBRF), and it is more distantly related to the Borrelia species that cause Lyme disease. This organism causes a febrile illness like TBRF, with body and join pain, fatigue, and rarely, rash, and has been detected in Ixodes scapularis and I pacificus ticks. These ticks are also the vectors for Lyme disease, anaplasmosis, and babesiosis.


The preferred method for detecting B miyamotoi is real-time PCR. Less sensitive and specific methods for detecting B miyamotoi and agents of TBRF include identification of spirochetes in peripheral blood films, cerebrospinal fluid (CSF) preparations, and serologic testing. This assay does not detect the Borrelia species that cause Lyme disease.

Reference Values



A positive result indicates the presence of Borrelia miyamotoi DNA and is consistent with active or recent infection. While positive results are highly specific indicators of disease, they should be correlated with symptoms and clinical findings of tick-borne relapsing fever.
