C. acnes owes its name to its ability to generate propionic acid. 2016-11-30 · Background Propionibacterium acnes (P. acnes) is an anaerobic, Gram-positive bacteria encountered in inflammatory acne lesions, particularly in the pilosebaceous follicle. P. acnes triggers a strong immune response involving keratinocytes, sebocytes and monocytes, the target cells during acne development. Lipoteicoic acid and peptidoglycan induce the inflammatory reaction, but no P. acnes Berthelot P, Carricajo A, Aubert G, et al.

[3] Propionibacterium acnes is a common cause of bacterial infection postoperatively in patients who have undergone shoulder surgery.. P acnes is a common gram-positive bacteria found commonly in the hair follicles and sebaceous glands that are abundantly common in the shoulder region. 2005-08-27 · INTRODUCTION: Propionibacterium acnes is a gram-positive pleomorphic rod-shaped anaerobic saprophyte of the skin, mouth and upper respiratory tract.

Morphology: small Gram-positive, pleomorphic bacilli. P. acnes are gram-positive anerobic bacteria that thrive in pilosabeaceous units. The bacterium drives inflammatory responses which initiates acne pathogenesis. P. acnes secreted lipases digest sebum triglycerides into fatty acid that leads to production of anti-microbial peptides such as Human defensin 1 and 2, cathelicidin and granulysin ( Dessinioti et al., 2010 ).

Even though C. acnes strains are the most active (68.8%), with clearly measurable hyaluronidase activity, C. avidum (45%) and C. granulosum (33.3%) strains are also positive, despite significantly lower activity . The impact of C. avidum hyaluronate lyase is still poorly understood. C. acnes carries two Propionibacterium acnes is known primarily as a skin commensal. However, it can present as an opportunistic pathogen via bacterial seeding to cause invasive infections such as implant-associated infections. These infections have gained more attention due to improved diagnostic procedures, such as sonication of explanted foreign materials and prolonged cultivation time of up to 14 days for Propionibacteria acnes (lat.

Propionibacterium) is a strain of gram-positive facultative anaerobic immobilized bacteria that synthesize propionic acid in the process of metabolism. Propionibacterium usually has the form of sharp sticks. Its size is about 0.5-0.8 per 1.0-1.5 μм. Propionibacterium acnes is known primarily as a skin commensal.
