7 Nov 2018 Abstract: Parvimonas micra is an anaerobic, Gram-positive coccus belonging to oral P. micra was isolated in both blood cultures. No more 


Prolonged enrichment cultures grew Parvimonas micra and Fusobacterium nucleatum, identified by Bactec (Becton Dickinson, USA) blood culture system and.

Consequently, apical periodontitis and infratemporal fossa abscess were identified as the primary sources of SPE. Although P. micra is one of the most The diagnosis of P. micra infection is mainly based on cul-ture of an adequate sample obtained from the site of infection. Culture of drainage or aspiration fluid, tissue samples or blood cultures are adequate for the diagnosis of P. micra. In the cas-es here included, the majority of patients were diagnosed by P. micra was identified on anaerobic culture after 72 hours and was susceptible to penicillin, metronidazole and clindamycin based on European Committee on Antimicrobial Susceptibility Testing (EUCAST) methodology. Transcutaneous vertebral bone biopsy and disc aspirate confirmed the same organism as in blood cultures, P. micra. Bacteria Collection: Parvimonas micra. NCTC Number: NCTC 11808.

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 the blood cultures of SPE patients. Here, we report a case of periodontal disease-associated SPE caused by Parvimonas micra (P. micra) which was identified by blood culture tests, and later successfully treated with a combination therapy of antibiotics along with aspiration and drainage of the concurrent infratem-poral fossa abscess. Case Parvimonas micra (Pm) has only been reported once before as the lone infecting organism of an orally originated, solitary brain abscess. Diagnosing brain abscesses caused by this Gram-positive anaerobic coccus, constituent of the oral cavity flora, is challenging, and an optimal treatment regimen has not been well established. An organism was isolated from an anaerobic culture of the abscess aspirate, and was identified as P. micra by a commercial kit and 16S rRNA sequencing.

After admission, Parvimonas micra (P. micra) was isolated from his blood culture.

the spine. Blood culture and transcutaneous vertebral biopsy were subsequently performed. Using the Tm mapping 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

Our case series and literature review showed that P. micra have been mainly identified in blood culture using MALDI-TOF MS and 16 s rRNA sequencing. Infection sites of P. micra were predominantly associated with GIT, oropharyngeal, vertebral spine, intra-abdominal region, pulmonary, and heart valves. Fusobacterium nucleatum, Parvimonas micra and Porphyromonas endodontalis were the most frequently found isolates, along with other taxa including newly named species (Prevotella baroniae and Dialister invisus) and as yet uncultivated phylotypes of Bacteroidetes. Two blood cultures grew Parvimonas micraand Gamella morbillorumand patient was later switched to ampicillin-sulbactam as per blood culture susceptibility results. Echocardiogram came negative for any evidence of infective endocarditis. CT abdomen/pelvis showed soft tissue mass in the ascending colon just superior to the ileocecal valve (fig.1, 2). Parvimonas micra is an anaerobic Gram-positive coccus.
