Borrelia lonestari is a spirochete transmitted by the Lone Star tick. Lone Star ticks can easily be identified by a single white dot on their backs, resembling a “lone starâ€. A bulls-eye rash similar to that of Lyme disease generally appears within a week of being bitten by the tick. Symptoms clinically resemble Lyme, including headache, fatigue, fever, muscle and joint pains but have no link to chronic, neurologic, or arthritic symptoms. The spirochete is the suspected cause of STARI, southern tick associated rash illness. Borrelia lonestari can be treated with antibiotics.
