Pseudomonas

Template:Infobox - bakterie

Pseudomonas aeruginosa is characterized by its green-blue pigment

The genus Pseudomonas belongs to the so-called gram-negative non-fermenting bacteria. The groups Stenotrophomonas and Burkholderia also belong to this group. Due to their common characteristics and traits, these genera can be put into context, in the medical sense, these genera are important mainly in terms of nosocomial infections.

Taxonomy

The taxonomy of the genus Pseudomonas is constantly renewed, the current classification is as follows:

  • class Gammaproteobacteria
  • order Pseudomonadales
  • family Pseudomonadaceae
  • genus Pseudomonas
  • this genus includes many species of bacteria, the most important of which include:
    • P. aeruginosa
    • P. alcaligenes
    • P. fluorescens
    • P. mendocina
    • P. putida
    • P. stutzeri


Occurrence

They are especially common in humid environments. So they inhabit soil, surface water, plants, but mainly medically important – hospital equipment. In pathogenesis, the products of these bacteria and the structure of their cell wall, specifically its outer parts formed by lipopolysaccharides, play a role. It is the construction of this membrane that is responsible for the resistance of bacteria to antibiotics. Multi-resistance to antibiotics is a major therapeutic problem. However, today it is undergoing a renaissance of colistin in parenteral form, which is often the last "in vitro" effective drug.[1]

Significant Representatives

The most important member of the genus Pseudomonas is the bacterium Pseudomonas aeruginosa .
