What should be considered a potential cause of folliculitis in whirlpool bath users?

In whirlpool bath users, folliculitis is commonly caused by Pseudomonas aeruginosa, which is a type of bacteria well-known for thriving in warm, moist environments such as hot tubs and whirlpools. This organism can colonize the skin's hair follicles, leading to inflammation and infection, particularly in individuals who use these facilities often.

Pseudomonas aeruginosa is capable of surviving in chlorinated water, and its presence in whirlpools, especially those that are poorly maintained, can lead to outbreaks of folliculitis. The clinical presentation often includes the development of itchy, painful red bumps around hair follicles, which typically occur in areas of skin that have been in contact with contaminated water.

While other bacteria can cause skin infections, they are less specifically associated with whirlpool bath settings compared to Pseudomonas aeruginosa. For instance, Staphylococcus aureus is a common skin pathogen but is not unique to the aquatic environment. Group A Streptococcus is known for causing abscesses and cellulitis rather than folliculitis in this context, and Escherichia coli is primarily associated with gastrointestinal infections and not typically linked to skin infections from whirlpool baths. Hence, when considering the unique environmental
