pseudomonas aeruginosa bacteriaWikipedia says this about pseudomonas aeruginosa bacteria:
Pseudomonas aeruginosa is a commonly occurring bacterium that can cause diseases in both animals and humans. It is found throughout the world where there is soil and is found in both soil and water and in most man-made environments. It thrives in normal atmospheres but can also thrive where there is little oxygen, which enables it to colonise many natural and artificial environments. It uses a wide range of organic material for food and, in animals, this means that damaged tissues or people with reduced immunity can become infected with the organisms. The symptoms of such infection are generalised inflammation and sepsis (production of pus). If such colonisations occur in critical body organs such as the lungs or the urinary tract and kidney, the results can be very damaging and potentially fatal[1]. Because it thrives on moist surfaces, it is also found on and in medical equipment including catheters and this can be the cause of cross infections in hospitals and clinics. It is also implicated in the condition "hot-tub rash" - a form of dermatitis associated with poor hygiene and low maintenance of hot tubs.

- cause of ear disease ( in ear disease: Perichondritis )
Infection of the cartilage of the outer ear, called perichondritis, is unusual but may occur from injury or from swimming in polluted water. It is due to a particular microorganism, Pseudomonas aeruginosa. There is a greenish or brownish, musty or foul-smelling discharge from the outer-ear canal, while the affected outer ear becomes tender, dusky red, and two to three times its normal...

...agricultural productivity. Thiobacillus denitrificans, Micrococcus denitrificans, and some species of Serratia, Pseudomonas, and Achromobacter are implicated as denitrifiers. Pseudomonas aeruginosa can, under anaerobic conditions (as in swampy or water-logged soils), reduce the amount of fixed nitrogen (as fertilizer) by up to 50 percent. Without denitrification,...
- effect on humans ( in pseudomonad )
Most species of the family are found in soil or water; some cause diseases in plants, and a few cause serious diseases in humans and other mammals. Pseudomonas aeruginosa, very common and widespread, is an opportunistic pathogen for man, which causes antibiotic-resistive infections in persons of weakened resistance. It has been implicated in hospital-acquired infections of surgical wounds and...
- infection treatment with polymyxin ( in polymyxin )
any of five polypeptide antibiotics derived from various species of the soil bacterium Bacillus that are active against gram-negative bacteria such as Escherichia coli and Pseudomonas aeruginosa. Polymyxins disrupt the cell membranes of bacteria, destroying their ability to function as osmotic barriers.
