In the Experimental Models and Subject Details: Bacteria section of the STAR Methods and the Key Resource Table of the above article, the ATCC strain number for Akkermansia muciniphila was incorrectly listed as BAA845. The correct number is BAA835. Additionally, in the legend of Figure 6B, the correct sentence should be, “Biochemicals, identified by Random Forests classification of colonic lumenal (left) and serum (right) metabolomes, that contribute most highly to the discrimination of seizure-susceptible (SPF CD, Abx KD) from seizure-protected (SPF KD, AkkPb KD) groups. n = 8 cages/group.” These errors, which have been corrected online and in the print version, do not affect the conclusions in the study, and we apologize for any inconvenience that it may have caused.
