Borrelia miyamotoi infection

Borrelia miyamotoi is a zoonotic pathogen that is transmitted by the same genus of ticks (ie, Ixodes) that transmits Borrelia burgdorferi (the agent that causes Lyme disease), Anaplasma phagocytophilum, Babesia species, and tickborne flaviviruses [1,2]. B. miyamotoi is in the same taxonomic group as agents of relapsing fever, such as Borrelia hermsii and Borrelia recurrentis. In the large majority of patients, it causes an acute febrile illness during the summer.

While there are reports and descriptions of B. miyamotoi infection in humans, understanding of the disease, its consequences, and its management remain limited. This topic will review the microbiology, epidemiology, clinical manifestations, diagnosis, and treatment of B. miyamotoi. Detailed discussions of other tick-borne pathogens are found elsewhere:

(See "Clinical manifestations of Lyme disease in adults".)

(See "Diagnosis of Lyme disease".)

(See "Treatment of Lyme disease".)
