Pseudomonas on skin typically manifests as a rash known as Pseudomonas folliculitis, often referred to as "Hot Tub Rash," characterized by distinctive pink-to-red bumps around hair follicles.
What Does Pseudomonas on Skin Look Like?
When Pseudomonas aeruginosa bacteria infect the skin, the most common presentation is Pseudomonas folliculitis, widely recognized as "Hot Tub Rash." This infection primarily targets hair follicles and has a specific appearance that helps in its identification.
Visual Characteristics of Pseudomonas Folliculitis
The rash caused by Pseudomonas on the skin exhibits several key features:
- Appearance: The individual lesions typically appear as small, solid bumps (papules) or pus-filled bumps (pustules).
- Size: These bumps usually measure between 2 and 10 millimeters in diameter.
- Color: They are characteristically pink-to-red.
- Location: The bumps are specifically located around hair follicles, indicating an infection within the hair follicle itself.
- Surface Texture: The lesions may sometimes be covered with scabs.
- Associated Symptoms: Beyond their visual appearance, the bumps are often itchy or tender to the touch.
Common Causes and Context
Pseudomonas folliculitis is most frequently linked to exposure to contaminated water, particularly:
- Poorly maintained hot tubs or spas: This is the most common source, hence the name "Hot Tub Rash."
- Contaminated swimming pools: Especially those with inadequate chlorine levels.
- Water slides and whirlpools: Other recreational water sources can also be culprits.
- Damp environments: Less commonly, contaminated loofahs or sponges can harbor the bacteria.
The bacteria thrive in warm, moist environments, making these settings ideal for proliferation and transmission. While the rash often resolves on its own within a week to 10 days, persistent or severe cases might warrant medical consultation.
