緑膿菌は空気感染する？
An opportunistic, nosocomial pathogen of immunocompromised individuals, "P. aeruginosa" typically infects the airway, urinary tract, burns, and wounds, and also causes other blood infections.
It is the most common cause of infections of burn injuries and of the outer ear (otitis externa), and is the most frequent colonizer of medical devices (e.g., catheters). "Pseudomonas" can be spread by equipment that gets contaminated and is not properly cleaned or on the hands of healthcare workers. "Pseudomonas" can, in rare circumstances, cause community-acquired pneumonias, as well as ventilator-associated pneumonias, being one of the most common agents isolated in several studies. Pyocyanin is a virulence factor of the bacteria and has been known to cause death in "C. elegans" by oxidative stress. However, salicylic acid can inhibit pyocyanin production. One in ten hospital-acquired infections is from "Pseudomonas". Cystic fibrosis patients are also predisposed to "P. aeruginosa" infection of the lungs. "P. aeruginosa" may also be a common cause of "hot-tub rash" (dermatitis), caused by lack of proper, periodic attention to water quality. Since these bacteria like moist environments, such as hot tubs and swimming pools, they can cause skin rash or swimmer's ear. "Pseudomonas" is also a common cause of postoperative infection in radial keratotomy surgery patients. The organism is also associated with the skin lesion ecthyma gangrenosum. "P. aeruginosa" is frequently associated with osteomyelitis involving puncture wounds of the foot, believed to result from direct inoculation with "P. aeruginosa" via the foam padding found in tennis shoes, with diabetic patients at a higher risk.
