Summary
Propionibacterium acnes, commonly linked to acne, can cause rare invasive infections. Its slow growth and low virulence may result in delayed diagnosis of these serious conditions.
Area of Science:
- Microbiology
- Infectious Diseases
Background:
- Propionibacterium acnes is a bacterium typically associated with acne vulgaris.
- This organism is a commensal of human skin but can occasionally cause invasive infections.
Purpose of the Study:
- To highlight the potential for Propionibacterium acnes to cause invasive infections.
- To illustrate the diagnostic challenges associated with indolent infections caused by this bacterium.
Main Methods:
- Case report presentation.
- Review of relevant literature on Propionibacterium acnes invasive infections.
Main Results:
- Propionibacterium acnes was isolated from an invasive infection.
- The infection presented with indolent characteristics, leading to diagnostic delays.
Conclusions:
- Propionibacterium acnes, despite its common association with acne, can be an opportunistic pathogen in invasive settings.
- Clinicians should consider Propionibacterium acnes in the differential diagnosis of indolent infections, especially when conventional pathogens are not identified.

01:19Bones of the Upper Limb: Humerus
13.4K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

01:15Bones of the Upper Limb: Ulna
10.5K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

01:09Bones of the Upper Limb: Radius
10.8K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...
