Parvimonas micra ( Pm) has only been reported once before as the lone infecting organism of an orally originated, solitary brain abscess. Mitis group streptococci clustered together with S. intermedius in the “yellow” complex, while S. constellatus clustered in the “orange” complex with Fusobacterium nucleatum, Fusobacterium periodonticum, Prevotella spp., Campylobacter spp., Eubacterium nodatum, and Parvimonas micra (Socransky et al., 1998). 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). Currently, there is limited use of P. micra in biotechnology, which includes the development of antibiotics and antibacterial monomers for use in periodontitis and cavity disinfection . This is due to P. micra having the potential to mediate infection and disease, such as periodontitis .

P. micra, formerly known as Peptostreptococcus micros 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.

We present a case of severe infective endocarditis caused by Parvimonas micra requiring valvular surgery despite appropriate antibiotics.

Parvimonas micra (previously named Peptostreptococcus micros and Micromonas micros) is a facultative pathogenic, anaerobic gram-positive bacterium of the human oral (gingival) microflora. The species, often associated with other microorganisms, is detected commonly in patients with periradicular lesions [ 3 ] and periodontitis.

Background: Brain abscess is a life-threatening entity which requires prompt and long-term antibiotic therapy, generally associated with surgical drainage, and eradicating the primary source of infection. Parvimonas micra (Pm) has only been reported once before as the lone infecting organism of an orally originated, solitary brain abscess.

It is the only species in its genus, and is a common constituent of mixed anaerobic infections such as intra-abdominal abscess. suggested, but not fully elucidated.

Following 14 days of intravenous antibiotic therapy with amoxicillin/clavulanic acid, the therapy was switched to oral amoxicillin for an additional 4 weeks. The patient reported a single episode of fever following a tooth extraction 10 days before the back pain began. P micra infection is an uncommon cause of liver abscess that could be overlooked. However, it is important to diagnose the etiology early in order to select the most appropriate surgical and antibiotic treatments. The most commonly isolated GPAC from clinical specimens include Finegoldia magna, Parvimonas Results: CRC-associated bacteria such as Parvimonas micra and Fusobacterium nucleatum were significantly (P < 0.005) decreased after surgery. On the other hand, cholate, carcinogenesis-associated deoxycholate, its biotransformed genes ( bai operon) from cholate to deoxycholate, and the contributing bacterium ( Clostridium scindens ) were
