P. aeruginosa is a Gram-negative, aerobic (and at times facultatively anaerobic), rod-shaped bacterium with unipolar motility. [80] It has been identified as an opportunistic pathogen of both humans and plants. [81] P. aeruginosa is the type species of the genus Pseudomonas. [82]
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer, diabetes, cystic fibrosis, [1] severe burns, AIDS, [2] or people who are very ...
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria.The 313 members of the genus [2] [3] demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. [4]
Pseudomonas aeruginosa can cause chronic opportunistic infections that have become increasingly apparent in immunocompromised patients and the ageing population of industrialised societies. The genome sequences of several pseudomonads have become available in recent years and researchers are beginning to use the data to make new discoveries ...
Pseudomonas aeruginosa. The molecule 2-heptyl-3-hydroxy-4-quinolone, also named the Pseudomonas quinolone signal (PQS), has been discovered as an intracellular link between the two major quorum sensing systems of P. aeruginosa; the las and rhl systems. [1]
The type order is the Pseudomonadales, which include the genera Pseudomonas and the nitrogen-fixing Azotobacter, along with many others. Besides being a well-known pathogenic genus, Pseudomonas is also capable of biodegradation of certain materials, like cellulose. [36] The Hydrogenophilalia are thermophilic chemoheterotrophs and autotrophs. [39]
Hot tub folliculitis, also called Pseudomonal folliculitis or Pseudomonas aeruginosa folliculitis, is a common type of folliculitis featuring inflammation of hair follicles and surrounding skin. [1]: 272 This condition is caused by an infection of the skin and hair follicles by the bacterium Pseudomonas aeruginosa.
It is classically associated with Pseudomonas aeruginosa bacteremia, but it is not pathognomonic. [1] Pseudomonas aeruginosa is a gram negative, aerobic bacillus. [2] This type of skin lesion was first described in association with Pseudomonas aeruginosa by L. Barker in 1897. [3] It was given the name "ecthyma gangrenosum" by Hitschmann and ...
