A Representative pictures of the fluorescent in vivo imaging of the gut area of Tg(mpeg1:mCherry / mpx:eGFPi¹¹⁴) larvae exposed to control media, 0.005 mg/ml and 0.01 mg/ml butyrate and 0.5 mg/ml and 0.7 mg/ml saponin. B Quantification of neutrophils and macrophages in the gut area of the zebrafish larvae (n = 10 in all groups except 0.7 mg/ml saponin where n = 3). *p ≤ 0.5, **** p ≤ 0.0001 Kruskal–Wallis test after testing for non-normally distributed data by Shapiro–Wilk test.
