Study Notes
Pseudomonas Aeruginosa Characteristics
- Exotoxin A is a virulence factor of Pseudomonas aeruginosa
- Pseudomonas aeruginosa is a common cause of urinary tract infections, respiratory infections, and sepsis
- On selective media, Pseudomonas aeruginosa can be identified by its ability to grow and produce a characteristic pigment
- Pseudomonas aeruginosa produces a pigment called pyocyanin
- Pseudomonas aeruginosa can be distinguished from other bacteria by its ability to oxidize glucose
- The mucoid exopolysaccharide (slime) produced by Pseudomonas aeruginosa provides protection from the host's immune system
- The main role of Pseudomonas aeruginosa's exotoxin A is to inhibit protein synthesis in host cells
- On MacConkey agar, Pseudomonas aeruginosa colonies are lactose-negative
- The distinguishing feature of Pseudomonas aeruginosa on selective media is its ability to grow and produce a characteristic pigment
