Abstract

Live Fast, Die Faster: Treatment of Mycobacterium tuberculosis infections is complicated by the need for a prolonged course of antibiotics to fully eliminate all the bacteria present in an infected individual. Most antibiotics target growth and division machinery; thus, Aldridge et al. (p. 100 , published online 15 November) postulated that heterogeneity in the growth properties of mycobacterial cells underlies variable antibiotic susceptibility. Cell division in mycobacteria was found to be asymmetrical, with one cell inheriting the growing pole and elongating rapidly, while the other cell elongated more slowly. Over multiple cell divisions, the rapidly growing cells became more susceptible to antibiotic treatment, helping to explain the observed heterogeneity in response to antibiotic therapy.

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.
