Because bacteria cause Pseudomonas aeruginosa infections, doctors treat them with antibiotics, reports WebMD. Sometimes doctors have difficulty selecting the proper antibiotics, as the bacteria display increasing resistance. Surgeons may occasionally need to trim a portion of infected tissue.
Pseudomonas aeruginosa infections are most dangerous at hospitals, where patients already have weakened immune systems from sickness and treatments, according to the Centers for Disease Control and Prevention. Catheters, breathing machines and post-surgery wounds expose patients to the bacteria. Multi-drug resistant Pseudomonas aeruginosa infections are sometimes fatal to critical care patients. People using swimming pools and hot tubs may contract them in the form of ear infections or skin rashes, and the bacteria can give people who wear contact lenses eye infections.
The best way to avoid Pseudomonas aeruginosa infections is to practice good hygiene to prevent its spread, advises WebMD. In hospitals, this involves health care personnel practicing frequent hand washing and isolating infected patients. Outside hospitals, people should wash their hands often, keep injuries clean and bandaged, and avoid touching the wounds of others. They should also avoid sharing personal hygiene items such as razors, washcloths and towels. When using antibiotics for bacterial infections, people should take the full course of medications exactly as doctors prescribe them.
