Isolation of Abiotrophia adiacens from a brain abscess which developed in a patient after neurosurgery

Abstract

We report the case of a patient who developed a large brain abscess after neurosurgery. Cerebrospinal fluid from the abscess drainage yielded Abiotrophia adiacens-specific PCR products and microorganisms that were identified by conventional microbiological methods and by 16S ribosomal DNA analysis as Abiotrophia adiacens, which was formerly classified as a member of nutritionally variant streptococci.
