A 12 year study of aerobic and anaerobic bacteria in intra-abdominal and post surgical abdominal wound infections. Surg Gyaecol Obstet 1989; 169 : 384–392. 10. Weiss A, Friendly D, Egkin K, Chang M, Gold B. [nature.com]

Vaginal and cervical florae can cause scalp wound infections in newborns after fetal monitoring. [emedicine.medscape.com]

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]

The phosphorylation of macrophage kinases, including cAMP-dependent protein-serine kinase (PKA) catalytic subunit beta, G protein-coupled receptor-serine kinase 2, mitogen-activated protein-serine kinase p38 alpha (p38a MAPK), extracellular regulated [ncbi.nlm.nih.gov]

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]

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]

We report the case of a 57 year-old woman with peripheral spondyloarthritis who developed knee septic arthritis by Peptostreptococcus asaccharolyticus. [ncbi.nlm.nih.gov]

[…] to microaerophilic streptococci, and in 15 (9%) of 176 patients who had P magnus infection. [7] The most frequent types of infections from which anaerobic gram-positive cocci were isolated in pure culture were soft tissue infections, osteomyelitis, arthritis [emedicine.com]

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]

(S. agalactiae, S. intermedius, S. mutans, S. sanguis I, and S. sanguis II). Only Peptostreptococcus anaerobius strains produced caproic and valeric acids in MNT broth cultures. [ncbi.nlm.nih.gov]

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]
