| Popis: | Pseudomonas pickettii is an aerobic, nonfermentative, Gram-negative rod-shaped, bacterium that has been isolated from soil, water, humans, and recently the bovine intestinal tract. It belongs to the rRNA group II of the genus Pseudomonas and has three biovars: Va-1, Va-2, and biovar 3/thomasii. P. pickettii can cause pneumonia, meningitis, endocarditis, and osteomyelitis in humans. It frequently is associated with nosocomial infections that often are linked to contaminated injectable solutions. P. pickettii exhibits remarkable ability to degrade a variety of toxic compounds such as chlorophenols, aromatic hydrocarbons, 2,4-dichlorophenoxyacetic acid, and pentacyclic triterpeniod compounds. The genes that encode for these properties are chromosome- and plasmid-associated. Strains of the organism also have demonstrated resistance to heavy metals, such as cadmium, copper, and zinc. This species can survive in a nutrient-poor environment and use a variety of toxic compounds as carbon and energy sources, making it an ideal candidate for study in the biodegradation of toxic compounds found in wastewater and soils. |
