A Rare Case of Parvimonas Micra Bacteremia Stephen C. 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

nucleatum polymorphum, Leptotrichia buccalis, Parvimonas micra (previously lead to systemic bacteremia or local transmission of pathogenic microbiota.

It can cause a broad range of invasive infections in humans, including intra-abdominal abscesses and bacteremia.It previously belonged to the genus Peptostreptococcus until anaerobic Gram-positive cocci have undergone extensive reclassification after the 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. Parvimonas micra is a fastidious anaerobic Gram-positive coccus which was originally classified as Peptostreptococcus mi - cros, being transferred to the Micromonas genus in 1999 and known as Micromonas micros 1. Later, Tindall and Euzeby in 2006 replaced Micromonas by Parvimonas… TaxLink: S10351 (Parvimonas micra (prévot 1933) tindall and euzéby 2006) - Date of change: 16/06/2007 by NCTC Up to 16/06/2007: ?

vaginalis), Finegoldia magna, and Parvimonas micra [5, 6]. They are frequently isolated from both local and systemic infections.

The PCR mixture consisted of H 2 O, 1 x HotStarTaq buffer, 10 mM dNTP mix, 1 U HotStarTaq polymerase (Qiagen, Germany) and 10 µM of each primer. 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. Among GPC, 90%–95% are susceptible to metronidazole, but rare nimB-positive, metronidazole-resistant strains of F. magna and Parvimonas micra have been described [35, 44].

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. Parvimonas micra is an anaerobic, Gram-positive coccus belonging to oral, gastrointestinal and Parvimonas micra bacteremia in a patient with colonic carcinoma bstract Background: Parvimonas micra is a gram-positive anaerobe and a part of the normal commensal flora of the gastrointestinal tract. Factors predisposing to anaerobic bacteremia include malignant neoplasms, periodontal disease, immune deficiencies, chronic renal Cases of meningitis due to P. micra have been reported in the setting of vertebral osteomyelitis and epidural abscesses and there has been no report of primary bacterial meningitis caused by this organism , , . We experienced a case of meningitis with bacteremia caused by P. micra after tooth extraction. Since anaerobic culture is not routinely performed with Cerebrospinal fluid (CSF) specimen, the pathogen was isolated only from blood cultures.

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.

Parvimonas micra is one of the best studied of the GPAC in terms of characterisation of its virulence factors.
