Fighting bacterial persistence: Current and emerging anti-persister strategies and therapeutics

Defraine, Valerie, Fauvart, Maarten, Michiels, Jan·2018·Drug Resistance Updates

Abstract

In addition to the well-known strategies of antibiotic resistance and biofilm formation, bacterial populations possess an additional survival strategy to endure hostile environments or antibiotic exposure. A small fraction of transiently antibiotic-tolerant phenotypical variants, called persister cells, is capable of surviving treatment with high doses of antibiotics. When antibiotic pressure drops, persisters that switch back to a normal phenotype can resume growth, ensuring survival of the bacterial population. Persister cells have been identified in every major pathogen, contribute to the antibiotic tolerance observed in biofilms, and are responsible for the recalcitrant nature of chronic infections. Also, evidence is accumulating that persister cells can contribute to the emergence of antibiotic resistance. Consequently, effective treatment of persister cells could greatly improve patient outcome. The small number of persisters and the redundancy in mechanisms of persister formation impede target-based development of anti-persister therapies. Nonetheless, the armory of anti-persister molecules is increasing. This review presents a comprehensive overview of anti-persister molecules and strategies described in literature to date and offers perspectives on potential anti-persistence targets and methods for the development of future therapies. Furthermore, we highlight in vivo model systems for pre-clinical testing and summarize ongoing clinical trials of candidate anti-persister therapeutics.

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.
