PSEUDOMONAS AERUGINOSA
| Class: | Gamma Proteobacteria |
| Genus: | Pseudomonas |
| Species: | Pseudomonas aeruginosa |
| Description: | P. aeruginosa is a Gram-negative, aerobic (and at times facultatively anaerobic), bacillus with unipolar motility.It has been identified as an opportunistic pathogen of both humans and plants.P. aeruginosa is the type species of the genus Pseudomonas.In certain conditions, P. aeruginosa can secrete a variety of pigments, including pyocyanin (blue-green), pyoverdine (yellow-green and fluorescent), and pyorubin (red-brown). These can be used to identify the organism.[ |

| Pathogenicity: | This organism is an opportunistic human pathogen. While it rarely infects healthy individuals, immunocompromised patients, like burn victims, AIDS-, cancer- or cystic fibrosis-patients are at increased risk for infection with this environmentally versatile bacteria. It is an important soil bacterium with a complex metabolism capable of degrading polycyclic aromatic hydrocarbons, and producing interesting, biologically active secondary metabolites including quinolones, rhamnolipids, lectins, hydrogen cyanide, and phenazines. Production of these products is likely controlled by complex regulatory networks making Pseudomonas aeruginosa adaptable both to free-living and pathogenic lifestyles. The bacterium is naturally resistant to many antibiotics and disinfectants, which makes it a difficult pathogen to treat. |
