According to the CDC:“Borrelia mayonii is  a new bacteria species recently found to cause Lyme disease in six people who live in the upper Midwestern United States. Worldwide, Lyme disease is caused by three main species of bacteria: Borrelia burgdorferi, B. afzelii, and B. garinii. Borrelia burgdorferi causes Lyme disease in the United States, while the other two species are the leading causes of Lyme disease in Europe and Asia. Borrelia mayonii is a new species that is genetically distinct from these three species and is the only species besides B. burgdorferi shown to cause Lyme disease in North America. Regardless of the bacteria’s species, the illness is still called Lyme disease or Lyme borreliosis.”
