persister
This term describes an entity characterized by endurance and survival against the odds. In a general human context, it carries a positive connotation of tenacity, grit, and unwavering determination, often implying a stubborn refusal to quit despite repeated setbacks.
In biological and medical contexts, the term is a technical designation for cells or organisms that survive lethal stressors, such as antibiotics, not through genetic mutation, but through a phenotypic shift into dormancy. This distinction is critical in microbiology to explain why some infections recur after treatment.
Meanings
A person who continues to exist or endure despite difficulties, opposition, or a challenging environment.
