4.3.4 Pseudomonas aeruginosa

P. aeruginosa is a glucose non-fermenting Gram-negative rod bacteria that can grow under a variety of conditions, surviving temperatures of up to 42°C.

Pseudomonas species have no specific nutritional requirements and are non-fastidious; therefore, they grow well on all standard laboratory media. They produce colonies that are usually large and smooth with flat edges. P. aeruginosa is oxidase-positive; therefore, when coupled with colonial morphology, the results of the oxidase test can aid in providing preliminary identification for isolates.
