Alpha diversity (Observed OTUs, Chao1, Inverse Simpson, Shannon index) of rainbow trout fecal microbiome communities. These measures were assessed in the feces of control, oxytetracycline (OTC)-, and sulfadiazine/trimethoprim (SDZ/TMP)-treated rainbow trout at 10 dpa and 25 dpc. Error bars indicate the 95% confidence interval; the top, middle, and bottom of each box represent the 75th, 50th, and 25th percentiles, respectively. Groups with different letters were significantly different (p-value ≤ 0.05) based on Welch’s ANOVA test
