“…A controversial hypothesis is the induced enteritis due to saponins and/or to the gut microbiota; as it is well known that gut bacteria promote intestinal inflammation (e.g., Ding et al., ; Peek & Blaser, ; Yan, Yang, & Ji, ). However, to the author's knowledge, no information is available on the effect of soy saponins on gut microbiota in salmonids, in contrast to that reported for other sources of saponins on gut microbiota of endothermic animals (Chen, Tai, & Hsiao, ; Gong, Xiao, Wang, & Yang, ; Juan, Zhang, Wang, An, & Wang, ; Wan et al., ; Zhang, Xie, Zhang, & Zhang, ). However, it is revealed that SBMIE lead to modulation of the Atlantic salmon gut microbiota (Reveco et al., ) and bacterial DNA in rainbow trout plasma (MosberianâTanha et al., ), as well as oxazoleâinduced enteritis in zebrafish modulate the gut microbiota (Brugman et al., ).…”
