Mean % relative abundance of core OTU across treatments and time. Grey shaded OTUs were found in 100% of individuals at all time points. Bolded OTUs were significant for treatment x time interaction. Timepoints 1–6 correspond to treatment times (timeline: Fig. 1) as follows: (1) pre-application, (2) 48 h post-Btk, (3) 6 d post-Btk, (4) 10 d post-Btk, (5) 1 week post-Bd, (6) 2 weeks post-Bd
