Abstract

Antibiotic persisters are a sub-population of bacteria able to survive in the presence of bactericidal antibiotic despite the lack of heritable drug resistance mechanisms. This phenomenon exists across many bacterial species and is observed for many different antibiotics. Though these bacteria are often described as “multidrug persisters” very few experiments have been carried out to determine the homogeneity of a persister population to different drugs. Further, there is much debate in the field as to the origins of a persister cell. Is it formed spontaneously? Does it form in response to stress? These questions are particularly pressing in the field of Mycobacterium tuberculosis, where persisters may play a crucial role in the required length of treatment and the development of multidrug resistant organisms. Here we aim to interpret the known mechanisms of antibiotic persistence and how they may relate to improving treatments for M. tuberculosis, exposing the gaps in knowledge that prevent us from answering the question: Are all antibiotic persisters created equal?

  • Fungal persisters are often recalcitrant to multiple antibiotics, as has been observed in antibiotic persistence.

    “In antibiotic persistence, persisters are often recalcitrant to multiple antibiotics [49,50], which has been observed with fungal persisters as well.”

    From Antifungal persistence: Clinical relevance and mechanisms (2025) · cites this paper as [50]

    The “Multidrug persistence” section reports bacterial persister populations that tolerate some antibiotic combinations and show cross-tolerance to certain other drugs. It also says cross-tolerance varies by drug and cautions that finding persisters after separate drug treatments does not establish that the same persisters tolerate multiple antibiotics. The source therefore supports the possibility, but not the unqualified frequency implied by “often.” The citation is attached to the antibiotic-persistence clause, not the statement about fungal persisters.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
