What microbe is most commonly associated with skin infections in whirlpools?

Pseudomonas aeruginosa is the microbe most commonly associated with skin infections in whirlpools due to its environmental prevalence and ability to thrive in moist conditions, such as those found in whirlpools and hot tubs. This bacterium is known for its resilience and adaptability to different environments, making it particularly suited to survive in the warm, stagnant water of whirlpools.

Pseudomonas aeruginosa is opportunistic and can cause infections in individuals with compromised immune systems or those with pre-existing skin conditions. It is often implicated in cases of folliculitis, which is an inflammation of the hair follicles, typically seen after exposure to contaminated water. The organism can easily colonize the skin, particularly if the skin’s protective barrier is disrupted.

While other bacteria can cause infections, they are not as commonly linked specifically to whirlpool-associated infections. For example, Staphylococcus aureus, while a cause of skin infections, is generally more associated with direct contact or contamination rather than aquatic environments. Escherichia coli and Salmonella enterica are primarily linked to gastrointestinal issues and foodborne illnesses, making them less relevant in the context of whirlpool-related skin infections.
