Changes of intestinal microbial community in Lateolabrax maculatus after Aeromonas hydrophila infection

Chinese sea bass (Lateolabrax maculatus) is one of the most important farmed fish in China.Bacterial diseases have a relatively serious impact on the cultivation of Lateolabrax maculatus, which restricts the sustainable and healthy development of aquaculture industry.There are abundant microbes in the intestinal and intestinal microbes can help regulate many physiological functions of the host.And bacterial infections can affect the homeostasis of fish intestinal microbes.In this study, we analyze the abundance of intestinal flora before and after infection with Aeromonas hydrophila by 16S rDNA sequencing and explore the relationship between intestinal flora and host resistance to pathogen infection.
