qPCR data of the bacterial load in each zebrafish intestine. Similarities in bacterial load, as assessed by 16S rRNA gene real-time quantitative PCR (qPCR) between zebrafish intestinal homogenates are displayed with accompanying sample list. Statistical tests were performed with Bonferroni’s correction on log-transformed data. *, P ≤ 0.05; ***, P ≤ 0.0005. Fish numbers: control, n = 10; 254-93, n = 12; AM-19226, n = 12; V52, n = 8; E7946, n = 12; N16961, n =12.
