Clinical Information

Borrelia miyamotoi is a spirochetal bacterium. It is a member of the tick-borne relapsing fever borreliae and is more distantly related to the Borrelia species that cause Lyme disease. This organism causes a febrile illness with body and joint pain, fatigue, and, rarely, rash, and has been detected in Ixodes scapularis and Ixodes pacificus ticks. These ticks are also the vectors for Lyme disease, anaplasmosis, and babesiosis.

 

The preferred method for detecting B miyamotoi is real-time polymerase chain reaction. Less commonly, B miyamotoi spirochetes can be detected in cerebrospinal fluid preparations in patients with invasive neurologic disease. This assay does not detect the Borrelia species that cause Lyme disease.

Reference Values

Negative

Interpretation

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. Less commonly, this test may also detect the nucleic acid of other relapsing fever borreliae; when detected, the report indicates the presence of relapsing fever Borrelia species, not B miyamotoi.

Cautions

Inadequate specimen collection or improper storage may invalidate test results.

 

Borrelia miyamotoi DNA may be detectable for an unknown period of time after adequate treatment.
