Parvimonas micra (P. micra) is a Gram-positive anaerobic bacterium distributed in the oral cavity, with a potential to become pathogenic causing lung abscess. Due to the lack of specificity of symptoms and the difficulty in culture, the diagnosis of lung abscess associated with P. micra is delayed. It is essential to elucidate the clinical characteristics of lung abscess associated with P. micra. Methods: From January 2019 to July 2020, five patients with chronic lung abscess associated with P. micra diagnosed by pathological biopsy and metagenomic next-generation sequencing (mNGS) were analyzed in this retrospective study. Results: Among the five patients, four had a history of smoking, three had periodontitis, and two had a history of drinking. The average course of the disease was 6.5 months. Highdensity flake-like or mass shadows with irregular boundaries were observed in the chest computed tomography (CT) images of the five patients, and liquefactive necrosis was detected in the middle of the lesions; however, no gas-liquid plane or cavity was noted, making it difficult to distinguish a lung cancer. The pathological biopsy of the five patients showed chronic inflammation of lung tissue, and P. micra was detected by mNGS in the biopsy or bronchoalveolar lavage fluid samples. Two patients were treated with amoxicillinclavulanate, two had metronidazole, and one had moxifloxacin. Among them, four recovered after receiving antibiotic treatment, and the remaining one underwent surgical resection due to poor antibiotic treatment effect. Conclusion: Chronic lung abscess associated with P. micra, common in elderly male smokers with poor oral hygiene, is often diagnosed in a delayed manner and misdiagnosed as lung cancer. The mNGS technology is beneficial to the rapid determination of P. micra.

“…After reviewing the entire texts, 15 studies were excluded for the following reasons: two studies had been written in Korean or German, and in 13 studies, the samples used for detection were not blood samples. Finally, a total of 23 studies were identified, and 26 case reports were included in the final analysis ( Figure 1 ) [ 4 , 11 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ].…”

“…As P. micra is an anaerobic inhabitant of the oral microbiome, risk factors include dental procedures, periodontitis, tooth extractions, and oral infections, such as abscesses or caries on the lingual apex [ 7 ]. P. micra may be multi-drug-resistant and may co-infect with other multi-drug-resistant bacteria in relation to cephalosporins and quinolone, resulting in a polymicrobial etiology for endogenous oral infections, such as periodontitis, while also being detected in soft tissues, skin infections, and various abscesses [ 8 , 9 , 10 , 11 ]. P. micra co-pathogens associated with polymicrobial infections include Streptococcus , Bacteroides , and Fusobacterium [ 12 ].…”

Parvimonas micra (P. micra), a bacterium that colonizes the gastrointestinal tract, is often isolated from periodontitis and abscesses as part of a complex bacterial infection. However, reports of monobacterium infections due to P. micra are limited. Here, we report a case of monobacterial bacteremia caused by P. micra with the aim of identifying the source of the invasion and clarifying the clinical features. A 54-year-old patient presented with bacteremia due to P. micra and with an oral invasion that we suspected resulted from prior dental treatment. Using PubMed and Google Scholar databases, we undertook a systematic review of monobacteremia caused by P. micra. We identified 26 patients (mean age, 70.15 years) in our systematic review. P. micra bacteremia and its associated phenotypes were most frequently identified in spinal discitis, followed by epidural and lumbar abscesses, and infective endocarditis. The major risk factors were malignancy, diabetes mellitus, and post-arthroplasty. When P. micra is detected in blood cultures, evaluation and intervention for oral contamination may be indicated.

“…Cobo et al identified 31 cases of P. micra infection with the first documented case in 1986 [7]. The spine has been the reported preferred location of infection; however, P. micra has also been associated with heart valve infections and perirenal, hepatic, and intracranial abscesses [8][9][10][11]. The incidence of splenic abscesses is very low [12].…”

We report a case of a 76-year-old Caucasian male with bacteremia caused by Porphyromonas gingivalis and splenic abscess caused by Parvimonas micra. This patient presented with nonspecific symptoms: fever, chills, body aches, and shortness of breath. He was treated with IV piperacillin-tazobactam that was later switched to ampicillin sodium/sulbactam sodium during his hospital course and underwent a splenectomy. He ultimately expired due to acute respiratory failure and cardiac arrest, secondary to post-surgical complications. To our knowledge, this is the first case of P. micra and P. gingivalis coinfection.
