鸡肠道微生物菌群的建立发育、分布和生理学意义

Establishment, distribution and physiological significance of the intestinal microbiota in chicken

摘要:

鸡的胃肠道具有复杂的微生物菌群，该微生物菌群与宿主的肠道和整体健康密切相关，为了全面揭示鸡肠道微生物菌群的组成及其功能，本文对鸡肠道微生物菌群的建立发育、各肠段群落的分布及其生理学意义进行综述，从而为鸡肠道功能菌株的分离及有效利用，合理调控微生物菌群-宿主相互作用，提高饲料转化率和改善肠道健康提供理论依据。

Abstract:

The chicken gastrointestinal tract (GIT) harbors a complex microbial community. The intestinal microbiota is closely related to both the intestinal and overall health of the host. In order to get insights into the composition and function of chicken gut microbiota (intestinal microbiome) we provide an overview of the chicken gastrointestinal microbiota by focusing on the establishment and development, spatial distribution in all intestinal compartments and physiological significance. We foresee advances in strategies to isolate and effectively utilize the functional bacteria in chicken intestinal tract and reasonably manage/modulate the intestinal microbe-host interactions to enhance feed efficiency and improve gut health.
