Culturing the bacteria reveals specific pigmentation—such as the characteristic green pyocyanin or fluorescent pyoverdine—that aids in initial identification. It is a leading cause of pneumonia in ventilated patients and a common culprit in bloodstream infections associated with catheters.
Where Pseudomonas Infections Thrive: Common Sources and Environments
The genus is defined by its aerobic metabolism, meaning it requires oxygen to grow, and its distinctive single polar flagellum, which grants it remarkable motility. Modern diagnostics utilize mass spectrometry and polymerase chain reaction (PCR) assays to quickly identify the species and its resistance profile, which is essential for guiding effective antibiotic therapy.
However, for patients with burns, cystic fibrosis, cancer, or those undergoing chemotherapy, Pseudomonas aeruginosa can cause severe and often life-threatening infections. These bacteria possess efflux pumps that actively expel antibiotics and enzymes that can degrade drug molecules.
Where Pseudomonas Infections Come From and How They Spread
Understanding what defines Pseudomonas involves looking at their unique biological characteristics, their ecological roles, and the serious threats they pose to immunocompromised individuals. Clinical Impact and Pathogenicity The medical definition of pseudomonas is inextricably linked to its status as an "opportunistic" pathogen.
