a bacterial species found in soil, water, and commonly in clinical specimens (wound infections, infected burn lesions, urinary tract infections); the causative agent of blue pus; occasionally pathogenic for plants; usually causes infections in humans in whom there is a defect in host defense mechanisms. It is the type species of the genus Pseudomonas.
Synonym(s): blue pus bacillus
Etymology: Gk, pseudes, false, monas, unity
a species of gram-negative, nonspore-forming, motile bacteria that may cause various human diseases ranging from purulent meningitis to nosocomial infected wounds. Also called Pseudomonas pyocyanea.
pseudomonas aeruginosaA normal soil inhabitant and human saprobe/commensal which may contaminate various solutions and fluids in a hospital, causing opportunistic infection in immunocompromised patients.
Infective endocarditis in IV drug users, respiratory tract infections, urinary tract infections, bacteraemia, meningitis, “malignant” external otitis.
Aminoglycosides—e.g., gentamicin, amikacin, netilmicin, tobramycin, etc.
Pseudonomas aeruginosa is both invasive and toxicogenic, and infects patients in a 3-step process:
1. Bacterial attachment and colonization—mediated by pili and antiphagocytic effects of the organism’s polysaccharide capsule;
2. Local invasion—mediated by elastase and bacterial alkaline protease; and
3. Dissemination—high-dose tobramycin delivered by aerosol is reportedly effective in patients with cystic fibrosis.

Bacterial species found in soil, water, and commonly in clinical specimens (wound infections, infected burn lesions, urinary tract infections); produces blue pus.
A species that produces a distinctive blue-green pigment, grows readily in water, and may cause life-threatening infections in humans, including nosocomial pneumonia, urinary tract infections, and sepsis. It may also cause folliculitis, malignant otitis externa, and skin infections in patients who have suffered burns. See: illustration

a genus of gram-negative, strictly aerobic bacteria, some species of which are pathogenic for plants and vertebrates.
a common isolate from wounds, burns and urinary tract infections and from many other accumulations of pus in all species. Also commonly found in otitis externa, fleece rot in sheep, and some cases of bovine mastitis. Its presence may be indicated by a distinctive blue or green color of the pus or infected site.
a common cause of food spoilage and a frequent isolate from wounds and other contaminated sites in animals.
