In earthworms that were sampled at ‘bacterial challenge day 2’, treatment (i.e., pre-treatment exposure followed and bacterial challenge combined) had a nearly statistically significant effect on the bacterial community composition in earthworms, with treatment explaining 24% of the total variance (Permanova: F (5,23) = 1.423, p = 0.075) ( Figure S4 ).
