A diverse and dynamic microbial community (known as microbiota) resides within the pig gastrointestinal tract (GIT). The microbiota contributes to host health and performance by mediating nutrient metabolism, stimulating the immune system, and providing colonization resistance against pathogens. Manipulation of gut microbiota to enhance growth performance and disease resilience in pigs has recently become an active area of research in an era defined by increasing scrutiny of antimicrobial use in swine production. In order to develop microbiota-targeted strategies, or to identify potential next-generation probiotic strains originating from the endogenous members of GIT microbiota in pigs, it is necessary to understand the role of key commensal members in host health. Many, though not all, correlative studies have associated members of the genus Prevotella with positive outcomes in pig production, including growth performance and immune response; therefore, a comprehensive review of the genus in the context of pig production is needed. In the present review, we summarize the current state of knowledge about the genus Prevotella in the intestinal microbial community of pigs, including relevant information from other animal species that provide mechanistic insights, and identify gaps in knowledge that must be addressed before development of Prevotella species as next-generation probiotics can be supported.

猪中的prevotella：与生产和健康的正面和负面关联

猪胃肠道（GIT）内有一个多样化的动态微生物群落（称为微生物群）。微生物群通过介导营养物质代谢，刺激免疫系统以及提供对病原体的定植抗性，从而有助于宿主的健康和生长。在增加对猪生产中使用抗菌素的严格审查所定义的时代，操纵肠道微生物群以增强猪的生长性能和疾病抵抗力最近已成为研究的活跃领域。为了制定针对微生物群的策略，或鉴定源自猪中GIT微生物群内源性成员的潜在下一代益生菌菌株，有必要了解关键共生成员在宿主健康中的作用。许多相关研究（尽管不是全部）都具有该属的相关成员Prevotella在猪的生产中具有积极的结果，包括生长性能和免疫反应；因此，需要对生猪生产情况下的属进行全面审查。在本综述中，我们总结了猪肠道微生物群落中普雷沃氏菌属的当前知识状态，包括来自其他具有机械学见识的动物物种的相关信息，并确定了在普雷沃氏菌物种发展之前必须解决的知识空白因为可以支持下一代益生菌。
