[The examination of cerebro-spinal fluid in the viroses of the central nervous system (author's transl)].

The general outlines for the isolation of viruses from the cerebro-spinal fluid are described. It is suggested to associate to the virus cultivation of the cerebrospinal fluid even the cultivation from other pathological materials as faringeal swabs and stools and the search for antibodies in the blood serum. Researches of viruses in cerebro-spinal fluid done by the Service of Microbiology of the Hospital of Verona have given in 55 cases examined during the year 1976 2 positive isolates; in both mumps virus has been isolated.
