Shrimp microbiome and immune development in the early life stages

Abstract

With its contribution to nutrition development and disease resistance gut microbiome has been recognized as a crucial component of the animal s health and well-being. Microbiome in the gastrointestinal tract constantly interacts with the host animal s immune systems as part of the normal function of the intestines. Interactions between the microbiome and the immune system are complex and dynamic with the microbiome shaping immune development and function. In contrast the immune system modulates the composition and activity of the microbiome. In shrimp as with all other aquatic animals the interaction between the microbiome and the animals occurs at the early developmental stages. This early interaction is likely essential to the development of immune responses of the animal as well as many key physiological developments that further contribute to the health of shrimp. This review provides background knowledge on the early developmental stage of shrimp and its microbiome examines the interaction between the microbiome and the immune system in the early life stage of shrimp and discusses potential pitfalls and challenges associated with microbiome research. Understanding the interaction between the microbiome and shrimp immune system at this crucial developmental stage could have the potential to aid in the establishment of a healthy microbiome improve shrimp survival and provide ways to shape the microbiome with feed supplements or other strategies. ? 2023 Elsevier Ltd
