Knowra Folliculitis Folliculitis Folliculitis is inflammation of one or more hair follicles, producing bumps or pustules that may itch, hurt, or crust. It can result from infection, irritation, or other skin conditions.
Staphylococcus aureus : A bacterium commonly found on skin and in the nose that can cause infections, including follicular infections. It is a frequent cause of bacterial folliculitis, especially when follicles are damaged.
Bacterial culture : A laboratory method that grows bacteria from a specimen to identify organisms and guide treatment. A culture from a pustule can identify bacteria when infection is recurrent or treatment-resistant.
Furuncle : A deep, painful infection of a hair follicle and surrounding tissue, commonly forming an abscess. A furuncle is a deeper, more localized form of follicular infection than superficial folliculitis.
Hair follicle : A skin structure that surrounds the hair root and produces a hair shaft. Folliculitis begins in this structure, which opens onto the skin surface.
Pseudomonas folliculitis : A follicular rash caused by Pseudomonas bacteria, often appearing after exposure to contaminated hot-tub water. This named infection shows how waterborne bacteria can produce a characteristic folliculitis outbreak.
Topical antibiotics : Antimicrobial medicines applied directly to the skin to treat susceptible localized infections. They may be used for limited bacterial folliculitis rather than systemic treatment.
Carbuncle : A cluster of connected boils involving multiple adjacent hair follicles and deeper skin tissue. Its connected deep abscesses distinguish it from scattered superficial follicular pustules.
Pilosebaceous unit : A skin unit consisting of a hair follicle, its hair, and an associated sebaceous gland. Nearby oil glands help explain overlap between follicular inflammation and acne-like eruptions.
Malassezia folliculitis : An eruption of itchy, uniform follicular bumps associated with overgrowth of Malassezia yeast. Yeast-driven inflammation can resemble acne but requires a different treatment approach.
Oral antibiotics : Antibacterial medicines taken by mouth to treat infections requiring treatment beyond the skin surface. Extensive or severe bacterial folliculitis may warrant systemic therapy.
