  • Rod-shaped.
  • Gram-negative.
  • Flagellum one or more, providing motility.
  • Aerobic.
  • Non-spore forming.
  • Catalase-positive.
  • Oxidase-positive.

Is Pseudomonas harmful to humans?

Pseudomonas bacteria are generally harmless. When they do cause an infection, it is usually mild in people who are otherwise healthy. However, Pseudomonas infections can be severe in people with a weakened immune system. It is essential for anyone at risk of complications to see a doctor as soon as possible.

What is the contribution of Zobell to biology?

ZoBell researched the special adhesive properties of organisms to surfaces, and experimented with mean of controlling such populations. He also was one of the pioneering scientists to study marine pollution.

Who is John ZoBell?

While at the Scripps Institute, ZoBell left his research in medical microbiology in favor of pursuing his interests in marine life. Thus, ZoBell was among the first generations of modern marine biologists.

What did Claude ZoBell’s research confirm about water and ocean-borne bacteria?

Claude Ephraim ZoBell’s research confirmed several behavioral characteristics of water and ocean-borne bacteria . ZoBell researched the special adhesive properties of organisms to surfaces, and experimented with mean of controlling such populations. He also was one of the pioneering scientists to study marine pollution.

What did Claude Ephraim ZoBell study?

Claude Ephraim ZoBell’s research confirmed several behavioral characteristics of water and ocean-borne bacteria . ZoBell researched the special adhesive properties of organisms to surfaces, and experimented with mean of controlling such populations.

Is Pseudomonas stutzeri Gram positive or negative?

negative Gram
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.

Where is Pseudomonas stutzeri commonly 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.

How is Pseudomonas stutzeri treated?

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.

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.

What disease does Pseudomonas aeruginosa cause?

What causes pseudomonas infection?

Pseudomonas infections are infections caused by a kind of bacteria called Pseudomonas that’s commonly found in soil, water, and plants. The type that typically causes infections in people is called Pseudomonas aeruginosa.

Why is Pseudomonas aeruginosa important?

Pseudomonas aeruginosa has become an important cause of gram-negative infection, especially in patients with compromised host defense mechanisms. It is the most common pathogen isolated from patients who have been hospitalized longer than 1 week, and it is a frequent cause of nosocomial infections.
