Is Pseudomonas stutzeri aerobic or anaerobic?

Is Pseudomonas stutzeri aerobic or anaerobic?

facultative anaerobe
P. stutzeri is a facultative anaerobe that utilizes respiratory metabolism with terminal electron acceptors such as oxygen and nitrogen. When grown anaerobically, organisms within the genus Pseudomonas are considered to be model organisms for studying denitrification.

Is pseudomonas a Stutzeri motile?

Pseudomonas stutzeri is a Gram-negative, rod-shaped, motile, single polar-flagellated, soil bacterium that was first isolated from human spinal fluid and is widely distributed in the environment.

Is Pseudomonas stutzeri Gram positive or negative?

Phenotypic traits of the genus include a negative Gram stain, positive catalase and oxidase tests, and a strictly respiratory metabolism. In addition, P. stutzeri strains are defined as denitrifiers.

Is P Stutzeri a lactose fermenter?

stutzeriin MacConkey agar showing 2-3 mm, raised, ruff, wrinkled non-lactose fermenting colonies with regular margin. Pseudomonas stutzeri is an aerobic, gram negative, oxidase positive non-fermenter bacillus.

What is Pseudomonas stutzeri infection?

Pseudomonas stutzeri is a ubiquitous Gram-negative bacterium that has been reported as a causative agent of some infections, particularly in immunocompromised patients but has rarely been reported as a cause of infective endocarditis.

How would you distinguish Pseudomonas species from E coli?

The key difference between E. coli and Pseudomonas aeruginosa is that E. coli is a facultative anaerobic bacterial species that belongs to family Enterobacteriaceae and genus Escherichia, while P. aeruginosa is an aerobic bacterial species that belongs to family Pseudomonadadaceae and genus Pseudomonas.

Where is P Stutzeri found?

stutzeri, which belongs to the genus Pseudomonas, is widely found in soil, fresh water, oceans and animals. It is an aerobic Gram-negative bacterium and a type of denitrifying bacterium [8]. A variety of strains of P. stutzeri have been isolated to study environmental bioremediation.

Where is Pseudomonas stutzeri commonly found?

The presence of P. stutzeri in virtually all environments has led to it being called “almost universal.” Soil and marine waters are two environments where P. stutzeri can be found. In soil, the organism has been found in the rhizosphere of cordgrass and other commonly grown plants including wheat, barley, and rice.

Which antibiotic family is the only known antibiotic to work on Pseudomonas stutzeri?

Patients with P. stutzeri infections often have serious underlying disease but generally respond to treatment with antibiotics including the aminoglycosides, the antipseudomonal penicillins, trimethoprim-sulfamethoxazole, and the third-generation cephalosporins.

How would you distinguish Pseudomonas species?

Pseudomonas species are Gram-negative, aerobic bacilli measuring 0.5 to 0.8, μm by 1.5 to 3.0 μm. Motility is by a single polar flagellum. Species are distinguished by biochemical and DNA hybridization tests. Antisera to lipopolysaccharide and outer membrane proteins show cross-reactivity among serovars.

Is Pseudomonas a coliform?

Pseudomonas, which lacks the ability to ferment lactose and is therefore not a coliform, has been described as the major contributor to PPC in the U.S. fluid milk industry (Ranieri and Boor, 2009; Martin et al., 2012).

Why do some organisms require oxygen?

Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
