Pseudomonas aeruginosa except in two important features—their fail- ure to produce indole and their ability to produce acid from certain carbohydrates. Bergey considered indole production sufficiently con- stant to justify the use of this characteristic in his key to separate Ps, aeruginosa from those species not producing indole.

Min Wu, Xuefeng Li, in Molecular Medical Microbiology (Second Edition), Introduction. Pseudomonas aeruginosa is a Gram-negative, aerobic rod bacterium of the Pseudomonadaceae family (a member of the Gammaproteobacteria) []. P. aeruginosa contains 12 other members in its family. Similar to other members of the genus, P. aeruginosa is commonly found in soil and water as well as .

INTRODUCTION. Pseudomonas aeruginosa is one of the most important and most commonly considered pathogens in the differential diagnosis of gram-negative infections. Consideration of this organism is important because it causes severe hospital-acquired infections, especially in immunocompromised hosts, is often antibiotic resistant, complicating the choice of therapy, and is .

Pseudomonas aeruginosa is a comm on bacterium, Gram-negative opportunisti c pathogen capable of infecting humans with compromised natural defens es and causing se .

Almost 50 years ago, Pseudomonas aeruginosa was rarely considered as a real pathogen. In the s it was recognized as the microorganism associated with bacteraemia in the neutropenic host. Nowadays, it is among the most common pathogens involved in nosocomial infections.

Pseudomonas aeruginosa can _____ colonize the respiratory and gastrointestinal tracts of hospitalized patients and particularly those treated with broad-spectrum antibiotics, exposed to respiratory equipment or hospitalized for extended periods?

A year-old woman presents to the emergency department with fatigue and abdominal pain. Her symptoms are associated with dysuria, hematuria, and increased urinary frequency. Physical examination is remarkable for bilateral flank pain, suprapubic tenderness, and costovertebral angle tenderness.

Pseudomonas aeruginosa is usually considered a relatively rare pathogen of pyogenic liver abscess in healthy children. A 3-year-old girl presented with fever, abdominal pain, and vomiting. Ultrasonography of the abdomen showed multiple liver abscesses.

Pseudomonas aeruginosa is a major cause of nosocomial infections. This organism shows a remarkable capacity to resist antibiotics, either intrinsically (because of constitutive expression of β-lactamases and efflux pumps, combined with low permeability of the outer-membrane) or following acquisition of resistance genes (e.g., genes for β-lactamases, or enzymes inactivating aminoglycosides or.
