Pseudomonas aeruginosa – the molecular tools of a bacterial survivor
The bacteria Pseudomonas aeruginosa can thrive in environments as different as the moist, warm tissue in our lungs, and the dry, nutrient-deprived surface of an office wall. Such adaptability makes it problematic in healthcare – where it causes infections in cases of cystic fibrosis, cancer, HIV, and other immune-compromised conditions – but also makes it a fascinating subject for study. How does Pseudomonas survive in so many environments? And can we use that knowledge to control it?
