Isolation of Abiotrophia/Granulicatella Species from a Brain Abscess in an Adult Patient Without Prior History of Neurosurgical Instrumentation

Authors: Yana D. Levin, MD, Carol-Lynn Petronaci, MD


To the Editor:

Organisms in the genera Abiotrophia and Granulicatella are fastidious Gram-positive nutritionally variant streptococci. Although part of normal human oral, genital, and intestinal flora, these organisms have been implicated in the development of endocarditis, vertebral osteomyelitis, endovascular infections, and central nervous system (CNS) infections after instrumentation. We report the first case of a brain abscess in an immunocompetent adult due to Abiotrophia/Granulicatella without preceding neurosurgical intervention.
