Parvimonas micra (P. micra) is a Gram-positive anaerobic bacterium with a diameter of 0.3–0.7 μm and grows slowly.It is arranged in pairs or chains and can be commonly found in the human oral cavity.1–3 P. micra causes bacteremia, rachitis, arthritis, infective endocarditis, liver abscess, renal abscess, brain abscess, pleural effusion, and lung abscess.4–13 A lung abscess Parvimonas micra is a gram-positive anaerobe coccus, usually of low clinical significance. They are most prominently part of the normal oropharyngeal flora, but can also be a commensal of the gastrointestinal or urogenital tracts. Infections with P. micra mostly occur in the context of polymicrobial infections resulting from these sites. The Parvimonas genus contains a single species, P micra, which formerly had been known as Peptostreptococcus micro and was renamed only in 2006.

micra) is a member of GPAC normally found in the oral cavity, respiratory system, gastrointestinal tract (GIT), and the female genitourinary tract. Originally known as Peptostreptococcus micros, the organism was reclassified as P. micra in 2006 [2].

Ross, MD Parvimonas micra is a gram positive anaerobic bacteria that is found in patients with chronic periodontal disease. It is often associated with mixed anaerobic infections abdominal in abscesses. It has been reportedrarely as a sole pathogen in To confirm the identity of the bacterial species P. micra, P. intermedia and P. nigrescens, the PCR (Polymerase Chain Reaction) method was used. P. micra were dissolved in 50 µL water MQ then frozen (- 20 ºC) until use. P. intermedia and P. nigrescens were not easily disrupted in MQ and therefore DNA from these strains was extracted Parvimonas micra is an anaerobic, Gram-positive coccus belonging to oral, gastrointestinal and genital flora, rarely causing infections in humans.

Parvimonas micra is an anaerobic organism which can become an opportunistic pathogen in certain conditions. Neoplasms, diabetes mellitus, decubitus ulcers, cirrhosis, surgical wounds, haematological disorders and immunosuppression conditions are the main underlying causes of bacteraemia, sepsis or serious anaerobic infections.
