Differentially abundant OTUs between the oxytetracycline (a, c) and tulathromycin (b, d) treated and the control cattle for the nasopharyngeal (NP) and fecal microbiota. Each circle is colored by phylum and represents a single OTU with the mean count number for each OTU indicated by the relative size. OTUs with positive log2 fold changes were more abundant in the control cattle
