Parvimonas micra has been identified as a prominent oral pathogen. This organism has been implicated in periodontal, soft tissue and bone infections. It causes a subacute presentation with high morbidity. We present a case of severe infective endocarditis caused by Parvimonas micra requiring valvular surgery despite appropriate antibiotics.

Parvimonas micra bacteremia

There was no evidence of abscess formation in either the examination or the imaging tests, but in the work-up that followed, a gastroscopy showed a stenotic oesophageal mass that turned out to be an invasive squamous cell carcinoma. Parvimonas micra bacteremia in a patient with colonic carcinoma Immune deficiency is a risk factor for anaerobic bacteremia. 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.

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. It was mainly deemed to cause bacteremia, septic bone and cerebral infections in patients which have undergone dental procedures or with suboptimal dental hygiene.

Description and significance P. micra is a gram positive cocci that forms pairs and groups of short chains, where it is not associated with the formation of spores [3, 4] . The Parvimonas genus contains a single species, P micra, which formerly had been known as Peptostreptococcus micro and was renamed only in 2006.13 It is a gram-positive anaerobic coccus and is a part of the normal flora of the human gingival crevice and gastrointestinal tract.

Since anaerobic culture is not routinely performed with Cerebrospinal fluid (CSF) specimen, the pathogen was isolated only from blood cultures. P. micra bacteremia were frequently associated with spondylodiscitis (29.6%), oropharyngeal infection (25.9%), intra-abdominal abscess (14.8%), infective endocarditis (11.1%), septic pulmonary Parvimonas micra (P.

This organism has been implicated in periodontal, soft tissue and bone infections. It causes a subacute presentation with high morbidity. We present a case of severe infective endocarditis caused by Parvimonas micra requiring valvular surgery despite appropriate antibiotics. To our knowledge, this is the second case report of Se hela listan på hindawi.com He was diagnosed with bacterial meningitis after a lumbar puncture, and blood culture revealed Parvimonas micra bacteremia. Although he had a history of extraction of a molar two weeks before symptom onset, there was no evidence of abscess formation on physical examination or imaging studies. Susceptibility testing of anaerobic bacteria recovered from selected cases can influence the choice of antimicrobial therapy.
