Zhongguo shiyan zhenduanxue, 2017 1肠道菌群与2型糖尿病人体胃肠道中存在着大量的正常菌群,其肠道内微生物主要由厚壁菌门、拟杆菌门、放线菌门、变形菌门以及疣微球菌门组成,而厚壁菌门及拟杆菌门占优势,某些病毒及真核生物也同时存在于肠道内[3]。肠道菌群和肥胖症的发生有很大的关系,其与2型糖尿病的关系亦是如此,有学者发现,改变肠道菌群构成 ...

野生动物学报, 2023 圈养是濒危野生动物重引入的重要措施之一，为了阐明圈养与野生、散放与圈养条件下鸟类肠道菌群的差异，在Web of Science和CNKI数据库中检索已发表的中英文文献，提取肠道微生物群落数据并使用R（Meta）进行分析。结果表明：圈养与野生相比，鸟类肠道厚壁菌门（Firmicutes）的丰度显著增加，拟杆菌门（Bacteroidetes）和绿弯菌门（Chloroflexi）的丰度显著下降，梭菌属（Clostridium）、拟杆菌属（Bacteroides）和双歧杆菌属（Bifidobacterium ...

Zhongguo shiyan zhenduanxue, 2020 艰难梭菌(Clostridium difficile)是一种革兰阳性厌氧菌,广泛存在于自然环境中,常见于动物和人体肠道中,艰难梭菌属于人体肠道的正常菌群。艰难梭菌感染(CDI)是由产毒株艰难梭菌过度繁殖导致肠道菌群失调并释放毒素引起的,被认为是干扰粪便微生物群的直接结果,导致艰难梭菌和毒素表达的过度生长。这与抗生素的使用密切相关 ...

Linchuang shenzangbing zazhi, 2018 近年来,随着科学技术的进步和发展,强大的基因组学和元数据分析的应用使人们对微生物群落的认知迅速增长。微生物群落的多态性和结构改变均会影响人体健康。然而,对于健康或疾病状态下宿主与微生物之间相互作用的潜在机制仍处于初级探索阶段。已有研究发现某些肾脏疾病患者肠道微生物发生变化,但其与疾病的发生、发展及预后关系仍不明确。本文主要回顾了宿主与微生物共生关系的改变,探讨肠道微生态与肾脏疾病的双向作用关系。

Haiyang yu huzhao卤虫(Artemia)是生存在高盐水体中的小型甲壳动物，其能够耐受多种极端环境，并可在不同的栖息地展现出不同的生理适应性，然而目前对于不同海拔地区卤虫肠道微生物组成及其与卤虫环境适应机制了解甚少。采用16S rRNA高通量测序和代谢组学技术，首次对来自高海拔地区的拉果错卤虫(A. tibetiana)和低海拔地区的渤海湾卤虫(A. franscicana和A.
