Pseudomonas aeruginosa - Coggle Diagram
Pseudomonas aeruginosa
morphology
motile - singular flagellum
short pili
Gram-negative rod
Cells/colonies
blueish-green pigments - pyocyanin
smooth, flat, circular - irregular edges
single cells or in pairs
metabolic properties
facultative anaerobe (grow in both)
oxygen utilisation
aerobic - oxygen is electron acceptor
anaerobic - nitrate as terminal electron acceptor (like in lungs of CF)
anaerobic - also grows in arginine
Heterotroph
can use over 100 organic molecules as carbon source.
psychrotolerant
grows in 4-42c (watercoolers/ tops of bottles)
genomes
Core genome - the parts that every microorganism has
Pan genome - union of all the genomes within the clade
opportunistic pathogen
hospital
severe burns
diabetics
newborns
contaminate devices like catheters
lungs of cystic fibrosis sufferers
WHO priority pathogen - Carbapenemase-resistant P. aeruginosa.
Virulence
Lipopolysaccharides - O-antigen - inflammatory
Biofilm - exopolysaccharide surrounds the cell
bacteriophages
host immune components
resists stressors
antibiotics
secretions
hydrogen cyanide
exotoxins
proteases
Pili/flagella - motility and adherence
Quorum-sensing - cell-to-cell communication
Anti-microbial resistence
protective polysaccharide layers
outer membrane prteins
