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 ). Orthopedic surgeons at our institution have noticed an increase in the number of infections due to Propionibacterium acnes, especially following operations on the shoulder. We collected P. acnes isolates from our hospital microbiology laboratory for 1 year and performed antimicrobial susceptibility testing on 28 strains from the shoulder. C. acnes, formerly called P. acnes, is the bacteria that, if overpopulated, can settle into sebaceous glands in your skin and trigger your body’s inflammatory response system. This is what causes the red, sometimes painful pimples you get when you have an acne breakout.

It uses sebum as a nutrient for growth and will continue to grow in line with the production of sebum. As such, people with acne will inherently have more of P. acnes in their follicles, as well as more oils on the skin to feed the bacteria.

Notes. Healthy pores and follicles of the human skin are normally populated by only P. acnes, while unhealthy and damaged pores may be more susceptible to infection from opportunistic skin pathogens. Cultures of P. acnes containing 1 x 10 5 cells / mL were prepared in Nutrient yeast glucose broth (NYG). A total of 20 µl of the bacterial suspension was added to 200 µl of two fold serially diluted plant extracts dissolved in NYG broth with a concentration range of 0.06 to 8 mg / mL.

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. The key to characterize a P acnes infection is to have a high clinical suspicion in a patient who continues to complain of pain and stiffness even if the other prototypical signs of infection are absent.

Propionibacterium acnes (P. acnes), sedan år 2016 Cutibacterium acnes (C. acnes), [1] [2] är en vanligt förekommande anaerob bakterie i huden. P. acnes finns och lever på huden hos alla människor. Bakterien har utpekats som en av orsakerna till att symtom av akne utvecklas (finnar, pormaskar och utslag). [3]

Propionibacterium acnes recently renamed Cutibacterium acnes, is a Gram-positive, non-spore-forming human skin commensal (normal bacteria of the skin) that prefers anaerobic growth conditions 1). Propionibacterium acnes (P. acnes) is a non-spore-forming, anaerobic, gram-positive bacillus. It is of low virulence and therefore can be a commensal in the lipid-rich sebaceous follicles and deep layers of the skin, conjunctiva, external auditory canal, respiratory tract and intestinal tract (1, 2).
