A systematic review of advances in intestinal microflora of fish

Intestinal flora is closely related to the health of organisms and the occurrence and development of diseases. The study of intestinal flora will provide a reference for the research and treatment of disease pathogenesis. Upon hatching, fish begin to acquire a microbial community in the intestine. In response to the environment and the host itself, the fish gut eventually develops a unique set of microflora, with some microorganisms being common to different fish. The existence of intestinal microorganisms creates an excellent microecological environment for the host, while the fish symbiotically provides conditions for the growth and reproduction of intestinal microflora. The intestinal flora and the host are interdependent and mutually restrictive. This review mainly describes the formation of fish intestinal flora, the function of normal intestinal flora, factors affecting intestinal flora, and a series of fish models.

Automated summary

Intestinal flora plays a crucial role in the health of organisms and the development of diseases, with fish acquiring a unique microbial community in the intestine. The host and the intestinal microorganisms have an interdependent and mutually restrictive relationship, creating a beneficial microecological environment for the host.
