title: [Viridans streptococci isolated from cerebrospinal fluid. Clinical significance of 9 cases].
abstract: Viridans streptococci (VS) are often isolated from cerebrospinal fluid (CSF). However, the significance of such isolates is poorly understood. In the present study we carry out a retrospective analysis of 9 patients in whom VS were isolated from CSF during a 1-year period at La Paz Hospital. Two patients (22.2%) had meningitis diagnosed through clinical, laboratory and bacteriologic findings. Both patients had predisposition diseases (previous difficult spinal tap, ventriculo-peritoneal shunt). The other isolations were considered as contaminants. Three patients (33.3%) with no VS meningitis had other different serious disease (sepsis without bacteriologic confirmation). VS are isolated with relative frequency from CSF, although they cause meningitis in less than one-quarter of the cases (those who have a predisposition disease). In the other cases, VS are isolated as contaminants of CSF and other disease should be search as cause of patient symptoms.
