This paper provides an overview of the research published concerning the bacteria that causes Lyme disease--a spirochete identified as Borrelia burgdorferi, or Bb. It describes the genetic complexity of Bb, a variety of mechanisms by which it may persist, and research studies that suggest persistence of the spirochete in both animals and humans. This review also discusses the formidable public health challenge that this complicated organism presents.
