What is Folliculitis?
What is Folliculitis?
A bacterial infection of the hair follicle, mainly caused by Staphylococcus aureus. It manifests as papules and pustules with surrounding redness.
How does Folliculitis develop?
How does Folliculitis develop?
The bacteria invade the hair follicle, causing inflammation and release of chemotactic factors and enzymes.
How is Folliculitis spread?
How is Folliculitis spread?
Direct contact with contaminated surfaces or sharing personal hygiene items, like razors or towels.

Study Notes
Integumentary - Bacterial Skin Infections
- Folliculitis:
- Caused by infection of the hair follicle, often by Staphylococcus aureus.
- Bacteria invade the follicle, causing inflammation and resulting in papules and pustules surrounded by redness.
- Transmission occurs through direct contact with contaminated surfaces, personal items, or contaminated water (like hot tubs).
- Risk factors include prolonged moisture, occlusive clothing, topical agents, poor hygiene, and skin trauma.
- Immunosuppressed individuals and those with predisposing skin conditions are more vulnerable.
- Cellulitis:
- Infection of the dermis and subcutaneous tissue, caused by Staphylococcus aureus, Streptococcus pyogenes, and other Streptococcal species.
- Bacteria penetrate through breaks in the skin (cuts, abrasions, insect bites).
- The infection spreads, causing localized inflammation, swelling, and redness.
- The affected area is warm, painful, and swollen, without a distinct border.
- Transmission is not direct but occurs through breaks in the skin from contaminated surfaces or other infections.
- Risk factors include prolonged moisture, occlusive clothing, topical agents, poor hygiene, and skin trauma.
- Immunosuppressed individuals and those with predisposing skin conditions are more vulnerable.
- Impetigo:
- Superficial skin infection primarily caused by Staphylococcus aureus and/or Streptococcus pyogenes.
- Bacterial toxins disrupt the skin barrier, leading to vesicle (blister) formation, which eventually ruptures and leaves honey-coloured crusts.
- Impetigo comes in two forms:
- Non-bullous impetigo: Flat, honey-colored crusts.
- Bullous impetigo: Large fluid-filled blisters (bullae) that rupture and crust.
- Highly contagious, transmitted via direct contact with infected individuals or contaminated surfaces (e.g., towels).
- Children are particularly susceptible, particularly in hot and humid climates.
- Poor hygiene, crowded living, and contact sports increase risk.
