    Pseudomonas is a type of bacteria (germ) that is found commonly in the environment, like in soil and in water. Of the many different types of Pseudomonas, the one that most often causes infections in humans is called Pseudomonas aeruginosa, which can cause infections in the blood, lungs (pneumonia), or other parts of the body after surgery.

    Pseudomonas aeruginosa is a common encapsulated, Gram-negative, rod-shaped bacterium that can cause disease in plants and animals, including humans. A species of considerable medical importance, P. aeruginosa is a multidrug resistant pathogen recognized for its ubiquity, its intrinsically advanced antibiotic resistance mechanisms, and its association with serious illnesses – hospital ...

    Pseudomonas aeruginosa is a gram-negative, rod-shaped, asporogenous, and monoflagellated bacterium that has an incredible nutritional versatility. It is a rod about 1-5 µm long and 0.5-1.0 µm wide. P. aeruginosa is an obligate respirer, using aerobic respiration (with oxygen) as its optimal metabolism although can also respire anaerobically on nitrate or other alternative electron acceptors. P. aeruginosa can catabolize a wide range of organic molecules, including organic compounds such as be...

    Protein F--Since P. aeruginosa is a Gram-negative microbe, it has an outer membrane which contains Protein F (OprF). OprF functions as a porin, allowing certain molecules and ions to come into the cells, and as a structural protein, maintaining the bacterial cell shape. Because OprF provides P. aeruginosa outer membrane with an exclusion limit of 500 Da, it lowers the permeability of the outer membrane, a property that is desired because it would decrease the intake of harmful substances into...

    Since P. aeruginosa can live in both inanimate and human environments, it has been characterized as a “ubiquitous” microorganism. This versatility is made possible by a large number of enzymes that allow P. aeruginosa to use a diversity of substances as nutrients. Most impressively, P. aeruginosa can switch from growing on nonmucoid to mucoid environments, which comes with a large synthesis of alginate. In inanimate environment, P. aeruginosa is usually detected in water-reservoirs polluted b...

    P. aeruginosa rarely causes disease in healthy humans. It is usually linked with patients whose immune system is compromised by diseases or trauma. It gains access to these patients’ tissues through the burns, for the burn victims, or through an underlying disease, like cystic fibrosis. First, P. aeruginosa adheres to tissue surfaces using its flagellum, pili, and exo-S; then, it replicates to create infectious critical mass; and lastly, it makes tissue damage using its virulence factors (21)...

    P. aeruginosa, as well as many other Pseudomonas, can degrade aromatic hydrocarbons such as methylbenzenes, which are the by-products of petroleum industries and are commonly used as solvents for enamels and paints as well as in the production of drugs and chemicals. Methylbenzenes are considered as environmental contaminants that are present in the atmosphere, underground and soils, and in surface water (25). P. aeruginosa can break down toluene, the simplest form of methylbenzene. P. aerugi...

    Effect of Spaceflight on Microbial Gene Expression and Virulence (Microbe) --The National Aeronautics and Space Administration (NASA) and the Biodesign Institute at Arizona State University are currently carrying out a research project called the Microbe Experiment.

These three microbes have bee...

    Pseudomonas aeruginosa is a Gram-negative rod (0.5–0.8 × 1.5–8 μm), which is mobile by polar flagella, and occurs singly, in pairs, or in short chains. This organism has a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor, although nitrate can be used as an alternate electron acceptor.
