Antibiotics and probiotics similarly alter the turkey mycobiome on day 6. (A) The relative abundance of the most predominant fungal taxa at the species, or lowest taxonomy level denoted, per sample. “Other” represents taxa comprising less than 20% of the total relative abundance per sample. (B) Principal-coordinate analysis of Bray-Curtis distances, colored by treatment. Differences in centroids by treatment (denoted by a diamond) were tested by PERMANOVA, with R2 and P values reported. Pairwise PERMANOVA was also performed on each treatment pair, with insignificant differences in centroids (P > 0.05) denoted by N.S. Full pairwise comparison results are listed in Data Set S1. (C) OTUs significantly different in centered log-ratio-transformed relative abundance (CLR RA) from one time point to the next. Stars denote OTUs significantly different in that treatment compared to its control treatment (P < 0.05). OTUs are labeled as their most specific taxonomic identifier available. For panels A to C, numbers were as follows: n = 14, control; n = 15, BMD; n = 16, T-Pbx; n = 12, FM-B11; n = 15, Prebx.
