Human infections with Borrelia miyamotoi, Japan

Emerg Infect Dis. 2014 Aug;20(8):1391-3. doi: 10.3201/eid2008.131761.


We confirmed infection of 2 patients with Borrelia miyamotoi in Japan by retrospective surveillance of Lyme disease patients and detection of B. miyamotoi DNA in serum samples. One patient also showed seroconversion for antibody against recombinant glycerophosphodiester phosphodiesterase of B. miyamotoi. Indigenous relapsing fever should be considered a health concern in Japan.
