Answer

Skin infections: Pseudomonas species do not grow on dry skin. Patients who are exposed to moisture have an increased risk for skin infections. Separation of the cuticle from the nail plate (ie, onycholysis) leaves the space between the proximal nail fold and nail plate exposed to bacteria, which results in chronic paronychia and pseudomonal toe web. The contamination of healthcare workers' protective gear has been linked to transmission of multidrug-resistant P aeruginosa (17.4%; 95% confidence interval, 9.4-25.4%). [7] People who wear heavy wet boots also are more likely to develop pseudomonal toe web infections. Children have higher risk than adults of developing folliculitis from exposure to Pseudomonas organisms in a contaminated whirlpool, home hot tub, water slide, physiotherapy pool, or contaminated loofah sponge.
