After this article [1] was published, concerns were raised about Figs 3 and 4. Specifically, the following panels appear similar, despite reporting results from different organisms:
The first author stated that the above concerns were the result of errors made during manuscript preparation. They provided underlying image and flow cytometry data for revised versions of Figs 3 and 4D, but not for the published figures, therefore the concerns remain unresolved. The underlying image data provided for the revised Fig 4D also raised further concerns with the reliability of these data. The original quantitative data underlying Figs 3 and 4 was not provided on editorial request.
In light of the above unresolved concerns which question the reliability of these data, the PLOS One Editors retract this article.
HL responded but expressed neither agreement nor disagreement with the editorial decision. HZ, LL, XS, WZ, and YS either did not respond directly or could not be reached.
The S. aureus and SB-3CT (5 µM) panels of Fig 3B report material similar to that published in [3], published in 2016 by Springer Nature, not under a CC BY license. The S. aureus and SB-3CT (5 µM) panels of Fig 3B are not offered under a CC BY license and are therefore excluded from this article’s [1] license.
