P. micra is an anaerobic Gram-positive cocci, and a known commensal organism of the human oral cavity and gastrointestinal tract. Although it has been classically described in association with endodontic disease and peritonsillar infection, recent reports have highlighted the role of P. micra as the primary pathogen in the setting of invasive infections.

Parvimonas micra is a Gram positive anaerobic coccus which is frequently isolated from dental plaque in patients with chronic periodontitis. It is the only species in its genus, and is a common constituent of mixed anaerobic infections such as intra-abdominal abscess.

There isn’t much information on this bacteria relating to vaginal infections or bacterial vaginosis, but P. micra is associated with biofilms of other bacteria, so can play a role in an infection or imbalance.

Chest X-ray findings of lung abscess usually present as a single cavity, rounded, thick-walled with an air-fluid level, and surrounding consolidation. Parvimonas micra (P. micra) are normal constituent of oral and gastrointestinal flora. While there is broad evidence to support the role of P. micra in periodontal and other oral infections, those outside the oral cavity have been underreported [4]. It is worthy to note that dental Parvimonas micra is a gram-positive anaerobic bacteria normally found in the mouth, being part of dental plaque.

Parvimonas micra is an anaerobic, Gram-positive coccus belonging to oral, gastrointestinal and genital flora, rarely causing infections in humans. It was mainly deemed to cause bacteremia, septic bone and cerebral infections in patients which have undergone dental procedures or with suboptimal dental hygiene.

P. micra bacteremia were frequently associated with spondylodiscitis (29.6%), oropharyngeal infection (25.9%), intra-abdominal abscess (14.8%), infective endocarditis (11.1%), septic pulmonary emboli (11.1%), and GIT infection (11.1%) in the literature review.

Parvimonas micra (P. micra) (17.5%) was the second most frequently identified GPA (MALDI-TOF MS); we then retrospectively reviewed electronic medical records for 25 P. micra bacteremia cases at our hospital. We also conducted a literature review of published cases in PubMed from January 1, 1980, until December 31, 2019; 27 cases were retrieved.
