method, Parvimonas micra was detected from a transcutaneous vertebral biopsy specimen in 3 h. Gram-positive cocci were also detected by Gram staining and P. micra was identified directly from the anaerobic blood culture by matrix-assisted laser desorption ionization-time of flight mass spectrometry.

P. micra is a gram-positive bacterium, which indicates that a large composition of its cell wall is made up of a thick layer of peptidoglycan. P. micra has no flagella and is associated with biofilms in the subgingival dental plaque of the human oral cavity.

It has been described in association with hematogenous seeding of prosthetic joints [1,2]. Although Gram staining showed Gram-negative rods (GNRs), the culture of vertebral bone was negative. In response to this discrepancy, 16S rRNA gene sequencing (16S rRNA) was performed and P. micra was detected. Parvimonas micra (Pm) has only been reported once before as the lone infecting organism of an orally originated, solitary brain abscess.

Infections with P. micra outside of the oral cavity are Although it is not highly pathogenic, it has been associated with infections, such as endocarditis, cerebral abscesses, bone and joint infections, and endophthalmitis. 1,2 Pleuropulmonary involvement, however, remains exceptional. 3 Another common commensal of the oropharyngeal cavity is Parvimonas micra, formerly Peptostreptococcus micros, a strictly anaerobic Gram-positive coccus that has Parvimonas micra, AF542231 gpac072 97.8 % Finegoldia magna, AF542227 gpac202 Anaerococcus hydrogenalis, D14140 gpac047 Anaerococcus vaginalis, AF542229 gpac215 gpac104 Anaerococcus murdochii, DQ911243 gpac126 Anaerococcus lactolyticus, AF542233 Anaerococcus prevotii, AF542232 Anaerococcus tetradius, AF542234 Anaerococcus octavius, Y07841 Chapter 42 Overview of Anaerobic Organisms Objectives 1.
