Note: + = Positive, - =Negative P. aeruginosa is a Gram-negative, aerobic (and at times facultatively anaerobic), rod-shaped bacterium with unipolar motility. [80] It has been identified as an opportunistic pathogen of both humans and plants. [81] P. aeruginosa is the type species of the genus Pseudomonas. [82]
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria.The 348 members of the genus [2] [3] demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches and hosts.
ESKAPE is an acronym comprising the scientific names of six highly virulent and antibiotic resistant bacterial pathogens including: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp. [1] The acronym is sometimes extended to ESKAPEE to include Escherichia coli. [2]
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer, diabetes, cystic fibrosis, [1] severe burns, AIDS, [2] or people who are very ...
Microscopic image of gram-negative Pseudomonas aeruginosa bacteria (pink-red rods). Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. [1]
A number of human pathogens belong to this class, including Yersinia pestis, Vibrio cholerae, Pseudomonas aeruginosa, Escherichia coli, and some species of Salmonella. The class also contains plant pathogens such as Xanthomonas axonopodis pv. citri (citrus canker), Pseudomonas syringae pv. actinidiae (kiwifruit Psa outbreak), and Xylella ...
The outer red layer in this diagram is the capsule, which is distinct from the cell envelope. This bacterium is gram-positive, as its cell envelope comprises a single cell membrane (orange) and a thick peptidoglycan-containing cell wall (purple). The bacterial capsule is a large structure common to many bacteria. [1]
Gram-negative bacteria are seen less frequently: Haemophilus influenzae , Klebsiella pneumoniae , Escherichia coli , Pseudomonas aeruginosa , Bordetella pertussis, and Moraxella catarrhalis are the most common. These bacteria often live in the gut and enter the lungs when contents of the gut (such as vomit or faeces) are inhaled.
