Pseudomonas pickettiiis 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 Pseudomonasand has three biovars: Va-1, Va-2, and biovar 3/thomasii. P. pickettiican cause pneumonia, meningitis, endocarditis, and osteomyelitis in humans. It frequently is associated with nosocomial infections that often are linked to contaminated injectable solutions. P. pickettiiexhibits 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. |
