摘要	Vibriosis is one of the most serious diseases that commonly occurs in aquatic animals, thus, shaping a steady inherited resistance trait in organisms has received the highest priority in aquaculture. Whereas, the mechanisms underlying the development of such a resistance trait are mostly elusive. In this study, we constructed vibriosis-resistant and susceptible families of the Pacific white shrimp Litopenaeus vannamei after four generations of artificial selection. Microbiome sequencing indicated that shrimp can successfully develop a colonization resistance trait against Vibrio infections. This trait was characterized by a microbial community structure with specific enrichment of a single probiotic species (namely Shewanella algae), and notably, its formation was inheritable and might be memorized by host epigenetic remodeling. Regardless of the infection status, a group of genes was specifically activated in the resistant family through disruption of complete methylation. Specifically, hypo-methylation and hyper-expression of genes related to lactate dehydrogenase (LDH) and iron homeostasis might provide rich sources of specific carbon (lactate) and ions for the colonization of S. algae, which directly results in the reduction of Vibrio load in shrimp. Lactate feeding increased the survival of shrimp, while knockdown of LDH gene decreased the survival when shrimp was infected by Vibrio pathogens. In addition, treatment of shrimp with the methyltransferase inhibitor 5-azacytidine resulted in upregulations of LDH and some protein processing genes, significant enrichment of S. algae, and simultaneous reduction of Vibrio in shrimp. Our results suggest that the colonization resistance can be memorized as epigenetic information by the host, which has played a pivotal role in vibriosis resistance. The findings of this study will aid in disease control and the selection of superior lines of shrimp with high disease resistance. Vibriosis is a bacterial disease that commonly occurs in animals, and causes high mortality and severe economic loss in aquaculture every year. Therefore, shaping a steady inherited resistance trait in organisms has received the highest priority in artificial selection. Whereas, the mechanisms underlying the development of such a resistance trait are mostly elusive. In this study, we found that penaeid shrimp can adopt a defense mechanism of colonization resistance against vibriosis. Wherein, a specific enrichment of a single probiotic species (Shewanella algae) in the intestine plays pivotal roles in reducing the Vibrio load and controlling vibriosis. Further evidence revealed that this process might be memorized and regulated by the host's epigenetic system. Activation of a subset of the host genes might provide proper niches for the enrichment of probiotics and simultaneous reduction of pathogens in the intestine through disruption of complete methylation. Together, our findings not only offer new insights into the key mechanisms in shaping disease resistance in shrimp, but also provide some clues for vibriosis control in aquaculture and for the selection of superior lines of shrimp with high disease resistance.
