Correction to: Nature Reviews Gastroenterology & Hepatology https://doi.org/10.1038/s41575-022-00631-9, published online 31 May 2022.

The originally published article contained two errors in Table 1 in the row for Faecalibacterium prausnitzii. The strain was listed as Faecalibacterium prausnitzii A2-65 instead of Faecalibacterium prausnitzii, and the entry in the ‘Potential mode of action’ column should have included IL-10 inducer with a citation for reference 142. These errors have been corrected in the HTML, PDF and print versions of the article.
