title: Bacteremic meningitis caused by Parvimonas micra in an immunocompetent host.
abstract: A 61-year-old man with chronic hepatitis B and dyslipidemia visited the emergency department with a fever and severe headache. He was diagnosed with bacterial meningitis after a lumbar puncture, and blood culture revealed Parvimonas micra bacteremia. Although he had a history of extraction of a molar two weeks before symptom onset, there was no evidence of abscess formation on physical examination or imaging studies. He was successfully treated with oral metronidazole for 12 days after 9 days of treatment with IV ceftriaxone and vancomcycin. This is the first report of primary bacterial meningitis caused by this organism, which indicates that this organism is capable of being a bacterial meningitis pathogen.
