Read condition-specific symptoms and clinical context for Pseudomonas aeruginosa. An environmental water-and-soil bacterium that mainly causes infections in hospital patients and damaged lungs.
CDC describes Pseudomonas as a group of bacteria commonly found in the environment, in soil and water, and states that P. aeruginosa can cause infections in the blood, lungs (pneumonia), urinary tract or other parts of the body after surgery. Patients in healthcare settings are at highest risk, especially people on ventilators, people with catheters, and people with open wounds from surgery or burns. Baron’s Medical Microbiology describes a Gram-negative rod of 0.5 to 0.8 by 1.5 to 3.0 micrometres that is motile by a single polar flagellum, usually carries pili, and produces pigments including pyocyanin. Healthy people occasionally get a short-lived skin rash from contaminated hot tubs; serious disease is largely an opportunistic, healthcare-associated problem rather than an everyday community infection.
CDC describes hot tub rash as a condition caused by prolonged contact between contaminated water and skin, caused by Pseudomonas aeruginosa, which is commonly found in the environment such as water or soil.
Possible symptoms: Itchy, red and bumpy rash; Pus-filled blisters around hair follicles; Worse where a swimsuit held water against the skin.
CDC states that mild rashes usually clear up in a few days without medical treatment, and advises checking with a healthcare provider if a rash gets worse or keeps coming back. This profile does not diagnose any rash.
CDC states that P. aeruginosa can cause infections in the blood, lungs (pneumonia), urinary tract or other parts of the body after surgery, and that patients on ventilators, with catheters, or with open wounds from surgery or burns are at highest risk.
The bundled CDC and StatPearls sources name the sites infected — bloodstream, lung, urinary tract, surgical wound, eye, ear — rather than a single symptom list, because what a person notices depends on which site is infected. No species-wide symptom list is invented here. StatPearls adds that chronic infection occurs in more than 60% of adults with cystic fibrosis and is linked to higher mortality, which is a clinical subgroup rather than a general-population risk.
CDC states that good hand hygiene and infection prevention and control can help reduce the risk of infection. Diagnosis and treatment of a suspected infection belong with a clinical team, not with this app.
