title: [Lymphocytic meningitis in Spain: a possible epidemic situation in 2000].
abstract: In order to clarify the unexpected increase in 2000 of lymphocyticmeningitis analyzed in the Centro Nacional de Microbiología,Instituto de Salud Carlos III, Madrid, here we present their microbiological features.
  
  
  METHODS
  Samples of 732 patients were tested by virological and serological methods to detect infections by neurotrophic agents.
  
  
  RESULTS
  Infections were identified in 375 (51%) cases. Nopolio enteroviruses were identified in 90% cases. Echovirus 30 and 13 were mainly characterized, the latter for the first time in Spain.
  
  
  CONCLUSIONS
  The emergence of Echovirus 13 may explain the past epidemic situation.
