Parvimonas micra Bacteremia in the Setting of a Hepatic Abscess: A Case Report.

ABSTRACT

Parvimonas micra is a Gram-positive anaerobic coccus that typically colonizes the oral cavity and gastrointestinal tract in humans. Though P. micra is typically associated with periodontal abscesses, it can also be an unlikely cause of bacteremia. Here, we report a case of P. micra bacteremia in the setting of a hepatic abscess. Antibiotic treatment of the bacteremia was initiated, and the entry source of the infection was investigated using various imaging techniques in the inpatient setting. A hepatic abscess was suspected to be the origin of infection for the P. micra bacteremia. Successful antibiotic treatment was confirmed by negative repeat blood cultures and an improvement in the patient's symptoms and clinical picture.
