Some GPAC, particularly strains of P. asaccharolyticus, decolorize rapidly with Gram's stain and can be confused with gram-negative anaerobes such as

Nonsporeforming, obligately anaerobic Gram‐stain‐positive cocci. Cells may occur in pairs, chains, and masses and are 0.3–0.7 µm in diameter. Carbohydrates are not fermented. Indole is negative. Two Parvimonas micra isolates were highly resistant to metronidazole (MIC 256 μg/mL) but were sensitive to other tested antibiotics.
We describe a rare clinical presentation of P. micra as spondylodiscitis and psoas abscess with haematogenous spread in an adult patient.
Gram positive cocci were seen in the initial Gram stain, but conventional cultures remained negative. However, 16S ribosomal RNA gene sequencing of the pus sample detected the presence of Parvimonas micra genome. Reaccumulation of the effusion required further drainage where again P micra was detected by 16S ribosomal RNA gene sequencing.

Two Parvimonas micra isolates were highly resistant to metronidazole (MIC 256 μg/mL) but were sensitive to other tested antibiotics. 1. Introduction. Gram-positive anaerobic cocci (GPAC) account for approximately 25–30% of all isolated anaerobic bacteria from clinical specimens . GPAC are the part of the commensal flora, but they often can become opportunistic pathogens. Using the Tm mapping method, Parvimonas micra was detected from a transcutaneous vertebral biopsy specimen in 3 h.

2019-11-19 · Parvimonas micra (P. micra) is a Gram-positive anaerobic cocci, normally found in the oral cavity and rarely causes severe infections. We describe a rare clinical presentation of P. micra as spondylodiscitis and psoas abscess with haematogenous spread in an adult patient. MRI lumbar spine detected L2 and L3 spondylodiscitis.
Gram positive cocci were seen in the initial Gram stain, but conventional cultures remained negative. However, 16S ribosomal RNA gene sequencing of the pus sample detected the presence of Parvimonas micra genome. Reaccumulation of the effusion required further drainage where again P micra was detected by 16S ribosomal RNA gene sequencing.
