鸡肠道微生物研究进展

Gut Microbiota of Chickens: A Review

定植于宿主肠道的复杂菌群结构对宿主健康具有非常重要的作用。非培养分子技术的发展使人们越来越深入了解肠道微生物菌群组成和多样性。在分析相关文献和生物信息数据基础上,本文旨在概述不同日龄鸡肠道微生物菌群组成和多样性、肠道菌群作用、饲粮与肠道菌群的关系,并总结饲喂抗生素对鸡肠道微生物的影响,讨论益生菌对鸡肠道菌群以及使用抗生素所造成的微生物生态失衡的调节潜能,为鸡肠道菌群研究提供参考。

The complex communities of microorganisms that colonize in gastrointestinal tract play an important role in the health of hosts. The development of cultureindependent molecular techniques has provided new in sights in the composition and diversity of the intestinal microbiota. Based on the related references and biologi cal data, the intestinal microbiota composition and diversity in chickens at different days of age, the role played by gut microbiota in host health and the association between diets and gut microflora were summarized. Moreo ver, the effects of antibiotic supplementation on the gut microbiota of chickens were reviewed. Finally, the po tential of probiotic microorganism to modulate the gut microbiota and the antibioticassociated microbial dysbio sis was discussed. Those could provide references for the study of gut microbiota in chickens.
