 AB    An in vivo diagnosis of progressive multifocal leukoencephalopathy
       (PML), a neurological opportunistic viral infection in AIDS patients,
       can be made only by brain biopsy. In order to identify viral particles,
       we examined the cerebrospinal fluid (CSF) of 15 AIDS patients with focal
       neurological signs by electron microscopy using negative staining
       technique. In 2 out of 3 patients with clinical and neuroradiological
       presumptive diagnosis of PML, the CSF examination revealed papova-like
       viral particles. Our results support the hypothesis that the severe
       cell-mediated immunodeficiency reactivates papovavirus from a latent
       state in the brain, leading to PML. Therefore, the CSF study by negative
       staining might be a useful test for an in vivo diagnosis of PML.
