Gram-positive anaerobes (GPAs) … Introduction. 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 an anaerobic Gram-positive coccus that is part of the normal flora of the mouth and the gastrointestinal tract. It can cause a broad range of invasive infections in humans, including intra-abdominal abscesses and bacteremia.

Factors predisposing to anaerobic bacteremia include malignant neoplasms, periodontal disease, immune deficiencies, chronic renal Parvimonas micra (P. micra) is a member of GPAC normally found in the oral cavity, respiratory system, gastrointestinal tract (GIT), and the female genitourinary tract.

Apart from immediately starting the patient on antibiotics, a thorough search for malignancy may be considered when a patient presents with anaerobic bacteremia, especially, when the source of infection is not known. 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 an anaerobic organism which can become an opportunistic pathogen in certain conditions.

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]. Parvimonas micra is one of the best studied of the GPAC in terms of characterisation of its virulence factors. The demonstration of synergy with facultative and anaerobic bacteria during the growth of abscesses, capsule formation and the ability to form hydrogen sulphide from glutathione have been described as important virulence factors (Brook & Walker, 1985 ; Brook, 1987 , 1988a ; Carlsson et al ., 1993 ).
