Where can Pseudomonas aeruginosa be found?

Pseudomonas aeruginosa commonly inhabits soil, water, and vegetation. It is found in the skin of some healthy persons and has been isolated from the throat (5 percent) and stool (3 percent) of nonhospitalized patients.

How do you get Pseudomonas bacteria?


  1. Inoculate P.
  2. Add 0.6 ml of overnight culture to cryogenic vial with 0.4 ml of 50% glycerol.
  3. Mix solution well by vortexing on a medium setting or by repeated inversions.
  4. Store bacterial glycerol stock in −80°C freezer.

What are the characteristics of Pseudomonas?


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

What is Pseudomonas aeruginosa resistant to?

Pseudomonas aeruginosa displays resistance to a variety of antibiotics, including aminoglycosides, quinolones and β-lactams (Hancock and Speert, 2000). Generally, the major mechanisms of P. aeruginosa used to counter antibiotic attack can be classified into intrinsic, acquired and adaptive resistance.

What is the benefits of Pseudomonas?

Plant-associated Pseudomonas live as saprophytes and parasites on plant surfaces and inside plant tissues. Many plant-associated Pseudomonas promote plant growth by suppressing pathogenic micro-organisms, synthesizing growth-stimulating plant hormones and promoting increased plant disease resistance.

How to describe the normal habitat for Pseudomonas aeruginosa?

Describe the normal sources (habitat) for Pseudomonas aeruginosa, Burkholderia cepacia, Burkholderia pseudomallei, and Burkholderia mallei, including the routes of transmission. 2. Identify the factors that contribute to the pathogenicity of P. aeruginosa and explain the physiologic mechanism for each.

What’s the best temperature to grow Pseudomonas putida?

It grows optimally at 25-30 C and can be easily isolated. Pseudomonas putida has several strains including the KT2440, a strain that colonizes the plant roots in which there is a mutual relationship between the plant and bacteria.

How big are the cells of Pseudomonas Burkholderia?

Organisms in these genera have many similar characteristics. They are aerobic, non–spore-forming, straight, slender, gram-negative bacilli with cells that range from 1 to 5 µ m long and 0.5 to 1 µ m wide.

How many species of Pseudomonas are there in the world?

P. xanthomarina. Pseudomonas is a genus of Gram-negative, Gammaproteobacteria, belonging to the family Pseudomonadaceae and containing 191 validly described species. The members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches.
