Role of persister cells in chronic infections: clinical relevance and perspectives on anti-persister therapies

Abstract

Certain infectious diseases caused by pathogenic bacteria are typically chronic in nature. Potentially deadly examples include tuberculosis, caused by Mycobacterium tuberculosis, cystic fibrosis-associated lung infections, primarily caused by Pseudomonas aeruginosa, and candidiasis, caused by the fungal pathogen Candida albicans. A hallmark of this type of illness is the recalcitrance to treatment with antibiotics, even in the face of laboratory tests showing the causative agents to be sensitive to drugs. Recent studies have attributed this treatment failure to the presence of a small, transiently multidrug-tolerant subpopulation of cells, so-called persister cells. Here, we review our current understanding of the role that persisters play in the treatment and outcome of chronic infections. In a second part, we offer a perspective on the development of anti-persister therapies based on genes and mechanisms that have been implicated in persistence over the last decade.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In some cases, clinical antifungal treatment fails even without resistance, leading to breakthrough or recurrent infections.

    “However, in some cases, even though devoid of resistance, the clinical treatment still failed, leading to breakthrough or recurrent infections [9–11].”

    From Antifungal persistence: Clinical relevance and mechanisms (2025) · cites this paper as [11]

    The Clinical relevance section (p. 1) says chronic infections can persist despite treatment when laboratory tests do not detect drug resistance. The Candidiasis section (p. 3) describes antifungal-tolerant Candida biofilm cells and links persistence to chronic infection, but it does not establish breakthrough infections or specifically report antifungal treatment failure without resistance.

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.
