title: Failure of Borrelia burgdorferi to survive in the skin of patients with antibiotic-treated Lyme disease.
abstract: BACKGROUND
  Borrelia burgdorferi has been cultivated from clinically normal skin (previous erythema migrans sites) after antibiotic therapy for Lyme disease.
  
  
  OBJECTIVE
  We investigated the possibility of similar findings in 13 of our patients with antibiotic-treated Lyme disease from whom B. burgdorferi was cultivated from their erythema migrans lesions before antibiotic therapy.
  
  
  METHODS
  After treatment with doxycycline or a combination of amoxicillin and probenecid, skin biopsy specimens were obtained from clinically normal skin adjacent to the previous biopsy sites and cultured.
  
  
  RESULTS
  B. burgdorferi was not cultivated from these posttreatment biopsy sites.
  
  
  CONCLUSIONS
  The failure of B. burgdorferi to survive in the former erythema migrans sites of our antibiotic-treated patients, as well as their favorable clinical response, supports the use of doxycycline or combined amoxicillin and probenecid in the treatment of early Lyme disease but does not preclude the survival of the organism in other tissues.
