Cerebellar abscess by Gemella morbillorum in a patient with inter-atrial communication.

Gemella morbillorum, a commensal of the oropharynx, upper respiratory, urogenital and gastrointestinal tract is rarely associated with infections in humans. However, an increasing number of infectious processes in different locations have been reported. Cerebral abscesses caused by these bacteria are extremely uncommon with only four cases previously described in the literature. We present the case of a cerebellar abscess by Gemella morbillorum in a 50 year-old man with inter-atrial communication dealt by surgical excision and antimicrobial therapy.
