Pseudomonas /Pseu·do·mo·nas/ (-mo´nas) a genus of gram-negative, aerobic bacteria, some species of which are pathogenic for plants and vertebrates. P. aerugino´sa produces the blue-green pigment pyocyanin, which gives the color to “blue pus” and causes various human diseases; P. acido´vorans, P. alcali´genes, P. fluores´cens, P. picket´tii, P. pseudoalcali´genes, P. pu´tida, P. putrefa´ciens, P. stut´zeri, and P. vesicula´ris are opportunistic pathogens.
Pseudomonas
pseudomembrane,
Pseu·do·mo·nas (s  d -m  ns, s-d m-ns)n. A phylum of gram-negative, rod-shaped, mostly aerobic flagellated bacteria, commonly found in soil, water, and decaying matter and including some species that are plant and animal pathogens. |
Pseudomonas
[so̅o̅dom′ənas]
Etymology: Gk, pseudes + monas, unit
a genus of gram-negative bacteria isolated from wounds, burns, and infections of the urinary tract that includes several free-living species in soil and water and some opportunistic pathogens, such as Pseudomonas aeruginosa. Pseudomonads are notable for their fluorescent pigments and their resistance to disinfectants and antibiotics.
pseudomembrane,
n a loosely adherent, grayish false membrane typical of intracellular coagulation necrosis. It is formed by necrotic epithelium embedded in fibrin, leukocytes, and erythrocytes. It is seen in necrotizing ulcerative periodontal disease, apthous ulcers, and diphtheria. Removal leaves a raw, bleeding surface.
Pseudomonas
n a genus of gram-negative bacteria that includes several free-living species of soil and water and some opportunistic pathogens isolated from wounds, burns, and infections of the urinary tract.
Pseudomonas
a genus of gram-negative, strictly aerobic bacteria, some species of which are pathogenic for plants and vertebrates.
Pseudomonas aeruginosa
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.
Pseudomonas fluorescens
a common cause of food spoilage and a frequent isolate from wounds and other contaminated sites in animals.
Pseudomonas mallei
see burkholderia mallei.
Pseudomonas pseudomallei
Pseudomonas putida
causes septicemia in aquarium fish.
