In the context of humans, it rarely infects uncompromised tissues, but almost any tissue can be infected if its defenses are compromised. Pseudomonas aeruginosa is an opportunistic pathogen, meaning it takes advantage of weakened host defenses to initiate infections. Epidemiological studies have shown that it is becoming more common as a nosocomial pathogen, and antibiotic resistance is on the rise in clinical isolates. Among bacteria, Pseudomonas species are known to be true pathogens of plants, and while Pseudomonas aeruginosa is occasionally pathogenic to plants, it has gained recognition as an emerging opportunistic pathogen with clinical relevance. This bacterium is commonly found in soil and water and can also be found on the surfaces of plants and occasionally on animals. Pseudomonas aeruginosa is the type species of its group, and there are 12 other members in this group.
The family Pseudomonadaceae includes various species of the genus Pseudomonas, which is further divided into eight groups based on conserved macromolecules like 16S ribosomal RNA.
It is a Gram-negative, rod-shaped, aerobic bacterium belonging to the bacterial family Pseudomonadaceae.
Pseudomonas aeruginosa is a bacterium classified under the Gamma Proteobacteria class of Bacteria.
