Pseudomonas

gram-negative bacterium
[C] Countable
pl: pseudomonases

This term carries a clinical and sterile weight, typically appearing in medical reports, microbiology textbooks, or pathology labs. It evokes an image of resilient, opportunistic organisms that thrive in moist environments and resist many common treatments. While the word describes a broad genus, in a hospital setting, it almost always triggers a sense of urgency regarding antibiotic resistance and the risk of nosocomial infections, particularly in patients with cystic fibrosis or severe burns.

Countable when referring to individual bacterial cells or specific species within the genus.
