Résumé
Enterococcus faecalis meningitis is an infrequent entity that accounts for less than 1 percent of all suppurative meningitis in the adult. Usually, this infection affects patients with compromised host defenses or those who have congenital or acquired CNS lesions mainly as intrahospitalary infections. An 85 year old woman from our community (Tandil county) without any predisposed condition, was admitted in the hospital in an unconscious state (grade 3 Glasgow's index), meningeal signs and purulent CSF, from which E. faecalis was isolated. The patient was treated with IV Ampicillin and Gentamycin (17 days), intrathecal Gentamycin (4 days) and ]V dexametasona (6 days). The clinical and bacteriological remission was achieved, without any sequel or relapse during 2 years follow up.
