Abstract: Probiotics play an important role in the intestinal tract of healthy teleost.They not only inhibit pathogenic microorganisms,but also stimulate and enhance the intestinal mucosal immune system and play an important role in intestinal immunity.In recent years,mucosal immunity of teleost has become a hot research topic because of its diversity and unclear definition.The direct contact between teleost and aquatic environment makes the surface of the intestinal tract to various pathogens.Immunoregulation is an effective preventive measure in teleost,and probiotics can enhance the intrinsic immunocompetent cells and factors on the surface of intestinal mucosa to play a role in the pathogen.Probiotics enter fish mainly by oral administration,and intestinal tract as its main target organ produces specific immune response to fish.Therefore,the study of probiotics affecting intestinal mucosal immune system deserves attention.Compared with mammals,teleosts have more diffuse intestinal lymphatic system.The immune cells necessary for the local immune response are abundant in the intestinal mucosa,and the local immune response can be monitored in the intestinal tract of the immunized fish.In this paper,the intestinal mucosal immune system of teleost and the effects of probiotics on intestinal mucosal immunity of teleost in recent years were reviewed,and the further research on probiotics of teleost was prospected,in order to provide reference for the follow-up study on the interaction between probiotics and teleost.

Key words: teleost; intestinal mucosal immunity; probiotics
