Skin as an outer layer of body and a main connection between the body and the environment is a way that pathogens can access the body; Therefore, it has a crucial protecting role for the body because of obstacle functioning and micobiota. Factors that seem to commonly contribute to the disease are follicular hyperkeratinization, propionibacterium acnes, sebum production, and inflammation; howev...
BACKGROUND In previous studies, Propionibacterium acnes was cultured from intervertebral disc tissue of ~25% of patients undergoing microdiscectomy, suggesting a possible link between chronic bacterial infection and disc degeneration. However, given the prominence of P. acnes as a skin commensal, such analyses often struggled to exclude the alternate possibility that these organisms represent p...
STUDY DESIGN Clinical research and animal experiment. OBJECTIVE To investigate whether lumbar disc degeneration is associated with Propionibacterium acnes (P acnes) infection. SUMMARY OF BACKGROUND DATA The hypothesis that herniated discs may be infected with P acnes by way of bacteremia is remarkable. This may bring a tremendous change in treatment of lumbar disc herniation (LDH). However,...
Acne vulgaris is a self-limiting skin disorder seen primarily in adolescents, whose aetiology appears to be multifactorial. The four main aetiological factors are hypercornification of the pilosebaceous duct, increased sebum production, colonization with Propionibacterium acnes, and subsequently the production of inflammation. Considerable investigation has addressed the immunologic reaction to...
BACKGROUND In the progression of acne vulgaris, the disruption of follicular epithelia by an over-growth of Propionibacterium acnes (P. acnes) permits the bacteria to spread and become in contact with various skin and immune cells. METHODOLOGY/PRINCIPAL FINDINGS We have demonstrated in the present study that the Christie, Atkins, Munch-Peterson (CAMP) factor of P. acnes is a secretory protein...
A 74-year-old man, with a permanent pacemaker placed 2 years ago for high-grade atrioventricular block, was admitted for worsening fatigue, confusion, and thrombocytopenic purpura without fever. White blood cell count and C-reactive protein were elevated, and echocardiography revealed a 6 × 3-cm echogenic mass surrounding the pacemaker leads. Multiple blood cultures were performed, and only 1 b...
Purpose. Low-virulence anaerobic bacteria, especially the Propionibacterium acnes (P. acnes), have been thought to be a new pathogeny for a series of disc diseases. However, until now, there has been no histological evidence to confirm this link. The purpose of this study was to confirm the presence of P. acnes in nonpyogenic intervertebral discs via histological observation. Method. Degenerate...
BACKGROUND/AIM One of the factors that affect the occurrence of acne is the presence of Propionibacterium acnes. The present study was conducted to compare the culture and polymerase chain reaction (PCR) methods for identifying P. acnes in lesions isolated from patients with acne. MATERIALS AND METHODS To examine the presence of P. acnes, 70 samples of acne lesions were collected. Microbial c...
Whether Propionibacterium acnes (P. acnes) causes surgical-site infections (SSI) after orthopedic surgery is controversial. We previously reported that we frequently find P. acnes in intraoperative specimens, yet none of the patients have clinically apparent infections. Here, we tracked P. acnes for 6 months in a mouse osteomyelitis model. We inoculated P. acnes with an implant into the mouse f...
