Quick Summary

Pseudomonas aeruginosa — Pseudomonas aeruginosa Pseudomonas aeruginosa bacteria from urine.

Pseudomonas aeruginosa is a bacterium belonging to the Pseudomonadaceae family. These rod-shaped cells, typically around 1 micrometer in diameter, are often motile due to flagella. While many pseudomonads inhabit soil and water, P. aeruginosa is an opportunistic pathogen that can cause serious, antibiotic-resistant infections in humans with weakened immune systems.1

This bacterium is frequently implicated in hospital-acquired infections, particularly in surgical wounds and burns. It poses a significant threat to individuals undergoing cancer treatment with immunosuppressive drugs. P. aeruginosa is also a cause of severe lung infections in people with cystic fibrosis. Unlike Streptococcus pneumoniae, which causes pneumonia and meningitis, P. aeruginosa's primary concern is its role as an opportunistic pathogen in vulnerable populations.12

Perichondritis
…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 thickness. Prompt antibiotic treatment is necessary to prevent permanent deformity of the outer…

denitrifying bacteria
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, however, the Earth’s supply of nitrogen would eventually accumulate in the oceans, since nitrates are highly soluble and…

neuraminidase
For example, the bacterium Pseudomonas aeruginosa produces a neuraminidase that appears to facilitate the formation of biofilms in the respiratory tracts of animals. Biofilm production is believed to contribute to the pathogenicity of this organism.
