Abstract:
This review discusses the biology and behavior of Propionibacterium acnes (P. acnes), a dominant bacterium species of the skin biogeography thought to be associated with transmission, recurrence and severity of disease. More specifically, we discuss the ability of P. acnes to invade and persist in epithelial cells and circulating macrophages to subsequently induce bouts of sarcoidosis, low-grade inflammation and metastatic cell growth in the prostate gland. Finally, we discuss the possibility of P. acnes infiltrating the brain parenchyma to indirectly contribute to pathogenic processes in neurodegenerative disorders such as those observed in Parkinson's disease (PD).
Insights
Propionibacterium acnes (P. acnes) is a skin bacterium linked to various diseases. This review explores its role in conditions from sarcoidosis and prostate cancer to neurodegenerative disorders like Parkinson's disease.
Area of Science:
- Microbiology
- Pathogenesis
- Dermatology
Background:
- Propionibacterium acnes (P. acnes) is a prevalent skin bacterium.
- P. acnes is implicated in the transmission, recurrence, and severity of various diseases.
- Understanding P. acnes's pathogenic potential is crucial for disease management.
Purpose of the Study:
- To review the biology and behavior of P. acnes.
- To explore P. acnes's role in epithelial and macrophage invasion.
- To discuss P. acnes's contribution to sarcoidosis, prostate cancer, and neurodegenerative diseases.
Main Methods:
- Literature review of P. acnes biology and behavior.
- Analysis of P. acnes's pathogenic mechanisms.
- Synthesis of evidence linking P. acnes to specific diseases.
Main Results:
- P. acnes invades and persists in epithelial cells and macrophages.
- P. acnes is associated with sarcoidosis, prostate gland inflammation, and metastasis.
- P. acnes may contribute to neurodegenerative disorders, including Parkinson's disease.
Conclusions:
- P. acnes exhibits diverse pathogenic capabilities beyond skin infections.
- Further research into P. acnes's systemic effects is warranted.
- Targeting P. acnes may offer therapeutic strategies for multiple diseases.

Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
