What is P acnes infection?

Although primarily recognized for its role in acne, P. acnes is an opportunistic pathogen, causing a range of postoperative and device-related infections. These include infections of the bones and joints, mouth, eye and brain.

What causes P. acnes?

Brüggemann says that teenagers are most vulnerable to outbreaks because surges in sex hormones during puberty drive the production of extra sebum in the skin. This extra sebum enables any P. acnes in the hair follicles to produce more of the fatty acids that aggravate inflammation, leading to more spots.

How do you treat P acne?

P. acnes is highly susceptible to a wide range of antibiotics, including beta-lactams, quinolones, clindamycin, and rifampin, although resistance to clindamycin is increasing. Treatment requires a combination of surgery and a prolonged antibiotic treatment regimen to successfully eliminate the remaining bacteria.

What are the symptoms of Propionibacterium acnes?

Deeper infection with P. acnes are often subtle and difficult to diagnose with subacute infection being the common presentation. Pain, stiffness, and implant loosening can be presenting symptoms.

How long does P. acnes last?

These results show that P. acnes could survive only in the presence of an implant for 6 months without contamination and retained the capacity for growth in vivo. In other words, P. acnes observed in the biofilm on the implant surface might produce anaerobic conditions to survive.
