ABSTRACT

Los estreptococos de grupo milleri se caracterizan por su tendencia a provocar infecciones piógenas invasoras en diferentes localizaciones. Las meningitis estreptocócicas no neumocócicas son poco frecuentes en pacientes adultos y pueden asociarse a la presencia de un absceso cerebral. Los abscesos cerebrales son colecciones localizadas dentro del parénquima cerebral que se originan como complicación de una infección, siendo los estreptococos microaerófilos y las bacterias anaerobiaslos microorganismos más frecuentemente aislados. Aunque no es inusual la presencia de colecciones intracraneales de etiología infecciosa en pacientes con infección por VIH-1, los abscesos cerebrales producidos por las bacterias piógenas habituales son muy infrecuentes y es T. gondiiel agente etiológico más frecuente. Aportamos un caso de meningitis y absceso cerebral por S. intermedius en un paciente con infección por VIH-1


Streptococcus milleri group have been recognized as an important pathogens for abscess formation in various organs. Streptococci other than Streptococcus pneumoniae are a rare cause of bacterial meningitis in adults and can be associated with the presence of an undiagnosed brain abscess. Brain abscess is a focal collection within the brain parenchyma wich can arise as a complication of a variety of infections. The most common etiologic organisms in clinical series have been microaerophilic streptococci and anaerobic bacterias. Although intracraneal mass lesions that occur as a result of infection have commonly been reported in patients infected with the human immunodeficiency virus, brain abscess due to the common bacterial pathogens are rarely described in HIV infected patients and Toxoplasma gondii is the organism most frecuently isolated from stereotactic brain biopsy in these patients. We report a patient with both HIV-1 infection and streptococcal meningitis secondary to brain abscess caused by S. intermedius
