The tick that primarily spreads Borrelia miyamotoi to humans is the Blacklegged Tick (Ixodes scapularis) and (I. pacificus).While rare, B. miyamotoi is a bacterium recently recognized to cause disease in humans. Although it sounds similar to the bacteria that causes Lyme disease, B. miyamotoi is more closely related to the bacteria that causes tick-borne relapsing fever.
The bacteria were first discovered in Japan in 1995. In the United States, the first human infections were reported in 2013.
B. miyamotoi infection can cause a Lyme-like-illness and symptoms may include fever, chills, muscle aches, fatigue, joint pain and headaches.
Diagnosis is by Polymerase chain reaction (PCR) tests that detect DNA from the bacteria and Serologic tests that detect antibodies made by the body in response to infection
