[Re-infection with Borrelia burgdorferi s.l in a patient with a history of neuroborreliosis--case report]. 
Reinfection with Borrelia burgdorferi s.l.,  which is likely in highly exposed persons, has not been described in Poland so far.  Symptoms of Lyme arthritis, preceded by typical skin lesion (erythema migrans) appeared in 46 years old women 5 years after successful treatment of borrelial meningitis.  Re-appearance of symptoms of Lyme borreliosis following localized skin lesion, after a long asymptomatic period, as well as accompanying increase in specific antibodies, point to reinfection with Borrelia burgdorferi sensu lato.  Different localization of systemic symptoms during two episodes of Lyme disease suggests infection with distinct genospecies of B. burgdorferi s.l.  This case confirms risk of recurrent infections with different B. burgdorferi s.l.  genospecies in inhabitants of highly endemic areas in the north-east of Poland, which may pose necessity of repeated antibiotic treatment.
