Parvimonas micra is a Gram positive anaerobic coccus which is frequently isolated from dental plaque in patients with chronic periodontitis.
[1] It is the only species in its genus, and is a common constituent of mixed anaerobic infections such as intra-abdominal abscess.
[2] It has rarely been implicated as a sole pathogen in septic arthritis, osteomyelitis and discitis associated with recent dental procedures.
