Propionibacterium acnes is a facultative anaerobic Gram-positive rod, abundant on the human skin, and mainly associated with the sebaceous glands of the shoulder and axilla (1). It is most commonly associated with the chronic skin disease acne vulgaris. The purpose of this study was to show the significance of a positive Propionibacterium acnes sample around a joint replacement. Records from the microbiology laboratory data over a 3-year period were reviewed to identify patients with prosthetic joints from whom Propionibacterium acnes was isolated at least once. In blood cultures, P. acnes grows better in anaerobic bottles but is also able to grow in aerobic bottles because of the anaerobic microenvironment that develops at the bottom of nonshaken bottles . The optimal temperature for growth is between 30°C and 37°C ( 47 ). Although Propionibacterium acnes ordinarily grows as an anaerobe, this organism was commonly seen on aerobic primary cultures (directly from skin) of the forehead, axilla, deltoid area, and antecubital fossa.

The cyst and associated infection completely responded to the surgical procedure along with a regimen of oral doxycycline monohydrate, 100 mg twice daily for 10 days. Discussion. P acnes is part of the normal skin flora. Furthermore, P. acnes was cultured more often from bone tissue and tissue surrounding foreign materials on day 14 than on day 5 (p 0.04).

The results show that stationary cultures of P. acnes grown at 37°C for 4 to 5 days in the appropriate medium produce biologically active preparations with satisfactory sensitizing activity. This is a preview of subscription content, log in to check access.

Propionibacterium acnes is normally present as normal flora on human skin and can be an opportunistic pathogen. It is available for purchase from the American Type Culture Collection, but you would probably need to obtain it through your school or a local university: Accurate detection and diagnosis of Propionibacterium acnes infection after shoulder surgery is often challenging. Aspiration and tissue cultures yield both false negative and false positive cultures and determination of infection is not always straightforward.

It is a human commensal organism, primarily found in skin and superficial mucosal sites, with a predilection for pilosebaceous follicles that exist in the upper body such as the shoulder region [ 8–10 ].

Organisms belonging to this second group are responsible for infections in humans and, less commonly, in animals.10 Propionibacterium acnes releases extracellular vesicles (EVs) which also induce cellular responses via TLR2 signal cascades. These Propionibacterium acnes-derived EVs induce IL-8 and GM-CSF and decrease epidermal keratin-10 and desmocollin, contributing to the development of acne lesions 38).

We identified 24 cases of P. acnes IE, 23 (96%) of which were either prosthetic valve endocarditis or IE on an annuloplasty ring. Invasive disease (71%) and embolic complications (29%) were common. All but one patient underwent surgery. Propionibacterium acnes was identified in 12.5% of routine blood cultures, 75% of blood cultures with extended incubation, 55% of valve cultures, and 95% of

Positive skin cultures for P. acnes increased from 10.5 % before incision to 31.9 % at closure. From Wikipedia, the free encyclopedia Cutibacterium acnes (formerly Propionibacterium acnes) is the relatively slow-growing, typically aerotolerant anaerobic, Gram-positive bacterium (rod) linked to the skin condition of acne; it can also cause chronic blepharitis and endophthalmitis, the latter particularly following intraocular surgery. 2017-06-01 · Propionibacterium acnes was defined as the causative pathogen if it was identified in at least two culture specimens, or identified with at least two different modalities: blood culture, valve culture, valve sequencing or histopathological demonstration of microorganisms.

P. acnes is part of the normal skin flora and is also often found as a contaminant in cultures. Objectives: Accurate detection and diagnosis of Propionibacterium acnes infection after shoulder surgery is often challenging. Aspiration and tissue cultures yield both false negative and false positive cultures and determination of infection is not always straightforward. Propionibacterium acnes is the most commonly isolated species and is often a contaminant in blood cultures along with other Propionibacterium spp. Administration of killedPropionibacterium acnes to experimental animals leads to the development of hypersensitivity to the lethal and cytokine-inducing effects of endotoxin. This sensitizing property ofP. acnes is not always expressed by different bacterial preparations.
