Pseudomonas stutzeri is a Gram-negative soil bacterium that is motile, has a single polar flagellum, and is classified as bacillus, or rod-shaped. [1] [2] While this bacterium was first isolated from human spinal fluid, [3] it has since been found in many different environments due to its various characteristics and metabolic capabilities. [4]
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 ...
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria.The 348 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]
Cetrimide also enhances the production of Pseudomonas pigments such as pyocyanin and pyoverdine, which show a characteristic blue-green and yellow-green colour, respectively. [ 3 ] [ 4 ] Cetrimide agar is widely used in the examination of cosmetics, pharmaceuticals and clinical specimens to test for the presence of Pseudomonas aeruginosa .
The oxidase test is used to determine whether an organism possesses the cytochrome c oxidase enzyme. The test is used as an aid for the differentiation of Neisseria , Moraxella , Campylobacter and Pasteurella species (oxidase positive).
Pseudomonas putida is a Gram-negative, rod-shaped, saprophytic soil bacterium. [1] It has a versatile metabolism and is amenable to genetic manipulation, making it a common organism used in research, bioremediation, and synthesis of chemicals and other compounds.
Pseudomonas fluorescens is a common Gram-negative, rod-shaped bacterium. [1] It belongs to the Pseudomonas genus ; 16S rRNA analysis as well as phylogenomic analysis has placed P. fluorescens in the P. fluorescens group within the genus, [ 2 ] [ 3 ] to which it lends its name.
Pseudomonas protegens are widespread Gram-negative, plant-protecting bacteria. [1] Some of the strains of this novel bacterial species (CHA0 and Pf-5, for example) previously belonged to P. fluorescens. They were reclassified since they seem to cluster separately from other fluorescent Pseudomonas species.
