What methods are there of killing pseudomonas bacteria?

Hi Ian,

Pseudomonas is a "water bug" and lives in flowers, ponds, sinks and the fresh vegetable section of the grocery store. The silvery oily sheen seen on the surface of stagnant water is due to pseudomonas. Pseudomonas aeruginosa are bacteria that can cause infections in patients with a weakened immune system. They can cause lung and eye infections. Cystic fibrosis patients and AIDS patients suffer from lung infections frequently. Infections can be treated with a range of antibiotics (penicillin and others). Eye infections are frequently seen with people wearing contact lenses. It has been suggested that Pseudomonas aeruginosa could live under long natural or artificial fingernails. This is not a proven fact. Common hygiene practice (washing hands with soap, thorough drying with a clean towel) should be sufficient under normal conditions. In hospitals standard hygienic practice is also sufficient. Killing of Pseudomonas in water is more problematic.

Pseudomonas can produce infections in fish (tropical aquarium!). In that case antibiotic treatment is needed, ask your vet for advise. For on-line information, start at the Virtual Museum for Bacteria, and go to the file specific on pseudomonas:

Pseudomonus like any bacteria can be "killed" by various methods. The method you choose depends on where the bacteria is located. Disinfectants such as bleach etc. can be used on counters or porcelain surfaces while autoclaving is the reliable way to eliminate all bacteria from an inanimate surface. Antiseptics or antibiotics are used for bacteria on or in a living organism. You need to be more specific as to where the Pseudomonas is before I can be more specifis as to what you should use.
