3B.2 - Pseudomonas aeruginosa

large, flat mucoid

The colony morphology of P. aeruginosa is described as:

beta-hemolytic

P. aeruginosa will be _____ on SBA plates.

motile

P. aeruginosa colonies have irregular boundaries because the organism is highly:

pos

P. aeruginosa is oxidase:

pos

P. aeruginosa is catalase:

oxidizer

The O/F media will show P. aeruginosa to be a(n):

maltose

P. aeruginosa cannot oxidize:

blue

Maltose O/F tubes with P. aeruginosa may show a _____ coloring.

grape, corn tortilla

The smell of P. aeruginosa has been compared to both ______ and _____.

pyocyanin

On an SBA plate, P. aeruginosa produces this pigment:

rainbow sheen

Pyocyanin is responsible for the _____ of P. aeruginosa colonies.

floroescein, pyorubin

P. aeruginosa may produce these pigments on specialized plating media:

ubiquitous in the environment

P. aeruginosa is a particularly problematic pathogen in hospital environments because it is:

skin infection

If a patient survives the first 3-4 days after a serious burn, the most common cause of death is:

p. aeruginosa, s. aureus

These two bacterial species cause most of the fatal skin infections in burn patients:

nosocomial infection

P. aeruginosa, while highly virulent, is typically only a concern as a(n):

urinary, respiratory

P. aeruginosa commonly causes infections of these tracts:

cystic fibrosis

P. aeruginosa is a particular problem for patients with this underlying condition:

CFTMR

The defective gene in cystic fibrosis is:

production of thick mucus

A key finding of cystic fibrosis is:

pseudomonas aeruginosa

80-90% of cystic fibrosis patients have this bacteria growing in their lungs:

necrotizing skin rash

P. aeruginosa can cause this skin infection, colloquially known as "hot tub syndrome":

highly antibiotic resistant

Though serious infections are rare in healthy individuals, P. aeruginosa is a major challenge to treat because it is:

cell wall porins

P. aeruginosa's antibiotic resistance is mostly due to a mutation of:

adhesins

This P. aeruginosa virulence factor mediates tissue adherance, particularly to epithelial cells:

alginate

This P. aeruginosa virulence factor is found in the capsule and protects from phagocytosis:

exotoxin A, exoenzyme S

These P. aeruginosa virulence factors work by inhibiting protein synthesis in the host cells:

elastolytic enzyme

This P. aeruginosa virulence factor is particularly damaging to the lungs:

lipopolysaccharide

This P. aeruginosa virulence factor is released when the bacterial cell dies and acts as an endotoxin, causing fever, inflammation, and even shock:

fluorescens

This Pseudomonas species is difficult to differentiate from P. aeruginosa but does not grow at 42C:

pseudomonas sp.

An organism which is oxidase positive and O/F glucose positive may be reported as:
