Intestinal metagenomic data of Penaeus vannamei in the study of shrimp "intestine-hepatopancreas axis"
The interaction between the gut and the liver plays a significant role in individual health and diseases. Mounting evidence supports that bile acids are important metabolites in the bidirectional communication between the gut and the liver. Most of the current studies on the "gut-liver axis" have focused on higher vertebrate animals such as mammals represented by humans and mice, however, few have been reported in lower invertebrate animals such as shrimp with an open circulatory system. In the present study, the basic characteristics and relationships of bacterial community composition and BA metabolism in intestine, hemolymph and hepatopancreas (three habitats) of P. vannamei after being fed diets supplemented with octanoic acid and oleic acid were achieved. The potential "intestine-hepatopancreas axis" with open circulatory system in shrimp was firstly explored from the perspective of microecology, which could greatly enhance our understanding and technical supports for lower invertebrate shrimp aquaculture management and disease microecological prevention and control.
