Quantitative PCR showed a progressive fall in DNA concentration in nonviable cell pellets and a concomitant rise in DNA concentration in the supernatant. DNA staining showed that some air-killed cells retained an intact cell wall. [ncbi.nlm.nih.gov]

Periodontitis
P. micros was isolated on PMM and identified biochemically and enzymatically from both adult periodontitis and early-onset periodontitis patients with higher percentages isolated from the diseased periodontal pockets of adult periodontitis patients; furthermore [ncbi.nlm.nih.gov]

Ulcer
Peptostreptococcus species were mainly isolated from infected atheroma and secondary infections due to ulcers; their resistance to five antimicrobial agents was generally low. [ncbi.nlm.nih.gov]
In general, Peptostreptococcus species, particularly P magnus, have been recovered more often from subcutaneous and soft tissue abscesses and diabetes-related foot ulcers than from intra-abdominal infections. [1] Peptostreptococcus infections occur more [emedicine.medscape.com]
[…] tract–associated infections; P magnus, P micros, P asaccharolyticus, P vaginalis, P tetradius, and P anaerobius in female genitourinary infections; and P magnus, P asaccharolyticus, P vaginalis, and P anaerobius in bone and joint infections and leg and foot ulcers [emedicine.com]
Peptostreptococcus spp. can cause infections such as gluteal decubitus ulcers, diabetes-related foot infections, and rectal abscesses. [en.wikipedia.org]

Foot Disease
This enzyme may be responsible for P. magnus playing a more central role in the pathogenesis of nonpuerperal breast abscess and diabetic foot disease than in intraabdominal sepsis. [ncbi.nlm.nih.gov]

Gram-Positive Coccus
Peptostreptococcus is an anaerobic gram-positive coccus that is encountered in dental and sinus infections, pelvic infections in women, osteomyelitis, arthritis, skin and soft-tissues infections, conjunctivitis and bacteraemia [1,2]. [ncbi.nlm.nih.gov]
Gram staining of the samples from the orbital floor revealed a Gram-positive coccus. After 5 days of culture, the organism was identified as a Peptostreptoccus, sensitive to metronidazole. [nature.com]
The results of intraoperative sample cultures were positive for P. micros, an anaerobic Gram-positive coccus. He was treated by the antibiotic therapy. [jocr.co.in]
Sarcina ventriculi GIFU 7886, a spore-forming anaerobic gram-positive coccus, clustered with Clostridium perfringens ATCC 13124T at a similarity value of 91%. [phe-culturecollections.org.uk]
Treatment
These findings point to starvation-survival capacity as a selection factor for microbial participation in post-treatment disease. [ncbi.nlm.nih.gov]

Etiology
Abstract P. micros is thought to be an important pathogen in the etiology of certain inflammatory lesions, however, the role of this microorganism is uncertain due to the lack of rapid and reliable method to identify this species. [ncbi.nlm.nih.gov]
Vancomycin, ceftriaxone plus metronidazole should be supplied when the etiological agent is unknown and drug resistance is probable 21. [scielo.br]
The microbiology of pyogenic brain abscess has Staphylococcus and Streptococcus as the leading etiologic pathogens in immunocompetent individuals. Peptostreptococcus is also recognized as a common cause of brain abscess in this patient population. [mdpi.com]
Epidemiology
These results demonstrate the genetic diversity of P. micros and the usefulness of AP-PCR for future epidemiological studies in understanding the role P. micros plays in periodontal disease pathogenesis. [ncbi.nlm.nih.gov]

Prevention
Depletion of reactive oxidative species by knockdown of TLR2 or TLR4, or incubation of cells with an antioxidant, prevented P anaerobius from inducing cholesterol biosynthesis and proliferation. [ncbi.nlm.nih.gov]
A patient's recovery from anaerobic infection depends on prompt and proper treatment according to the following principles: (1) neutralizing toxins produced by anaerobes, (2) preventing local bacterial proliferation by changing the environment, and (3 [emedicine.medscape.com]
When Peptostreptococci and other anaerobes predominate, aggressive treatment of acute infection can prevent chronic infection. [en.wikipedia.org]
